Abstract

The utility model relates to a floor combined horizontal type lathe. The lathe is characterized in that: a headstock in which a change gear is arranged is installed on the floor, an actuating motor is arranged on the back end of the headstock, and a main shaft and a chuck are arranged on the front end of the headstock; a tool carrier guide rail in parallel with the main shaft is arranged on the floor, and a slide carriage box and a double ram head and an actuating motor thereof are arranged on the tool carrier guide rail; two bar-shaped platforms with T-shaped grooves in parallel with the main shaft are fixed on the floor below the main shaft, and two static pressure holding frames for supporting work pieces like shafts are arranged back and forth on the two bar-shaped platforms; and a cardan joint for connecting work pieces like shafts is arranged on the chuck. Therefore, the distance from the center of the lathe to the floor is greatly reduced, the weight of the total lathe is also greatly reduced, and steel is saved. The lathe which needs less working space and is convenient and flexible for configuring auxiliary devices is suitable for the modernized production with high quality and efficiency. In addition, the lathe also has the advantages of simple structure, easy manufacturing, low cost and easy operation.

Description

Land the combined horizontal lathe

Technical field

The utility model relates to a kind of horizontal lathe, especially a kind of combined horizontal lathe that lands.

Background technology

Horizontal lathe generally is used for working shaft-like workpiece, known horizontal lathe structure: be shaped on two closed slides above the lathe bed, headstock and drive motors that change-speed gearing is arranged in one end of lathe bed is installed, the front end of headstock is equipped with main shaft and chuck, the side of headstock is equipped with feed rod and leading screw, the other end of lathe bed is equipped with top slide, is movably installed with the slip crate and the knife rest that are driven by feed rod, leading screw on the guide rail of lathe bed.The lathe of this structure is good at processing diameter and the not too big shaft-like workpiece of length ratio, and all very big shaft-like workpiece (because main shaft and top stressed excessive) of weight and length just can't firmly support, and therefore can't guarantee its machining accuracy.For head it off, on the guide rail of lathe bed, install two static pressure bracing frames additional, solved the firm support problem of workpiece.Because some part to be processed weight reach hundreds of ton, therefore also need the width of the body of lathe bed and highly all strengthens, so that the rigidity of raising lathe bed prevents to be out of shape.So, the huge workpiece and the height of lathe bed make the workpiece centre height very high, are unfavorable for that very the workman operates and lifts; In addition, the lathe volume and weight of this structure is big, manufacturing cost is high, installation is inconvenient.

Summary of the invention

The utility model lands the combined horizontal lathe for what solve that the technical problem that exists in the known technology provides a kind of simple in structure, low cost of manufacture.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of combined horizontal lathe that lands, comprise that inside is equipped with the headstock of change-speed gearing, be installed in the drive motors of headstock rear end, be installed in the main shaft and the chuck of headstock front end, the tool guide that have tooth bar parallel with main shaft, be installed on the tool guide and slip crate and knife rest the tooth bar engaged transmission, and drive the motor that slip crate and knife rest move, described headstock and tool guide all fix on the ground, on the ground below the main shaft, also be fixed with two the bar shaped platforms that have T-slot parallel with main shaft, two static pressure bracing frames that support shaft-like workpiece are installed before and after on the bar shaped platform, the universal joint that connects shaft-like workpiece is installed on the described chuck.

The utility model can also adopt following technical scheme:

Described knife rest both sides are separately installed with T shape ram.

Advantage and the good effect that the utlity model has are:

Because headstock is installed on the ground, and the static pressure of workpiece supports on the surface-based bar shaped platform, the height on lathe centre-to-centre spacing ground is reduced greatly, and alleviated the weight of whole lathe greatly, has saved steel; Its needed working space is less, and the workshop supporting with it, equipment (overhead crane) are also less; It is convenient, flexible to dispose other device, is fit to high-quality, high efficiency specialization, modern production; In addition the utility model also have simple in structure, cost is low, the advantage that is easy to make.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1.

Among the figure: 1, motor; 2, headstock; 3, chuck; 4, universal joint; 5, static pressure supports; 6, workpiece; 7, static pressure supports; 8, bar shaped platform; 9, bar shaped platform; 10, tool guide; 11, motor; 12, slip crate; 13, motor; 14, two ram heads; 15, motor; 16, slip crate; 17, motor; 18, two ram heads; 19, bearing; 20, base.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, Fig. 2, the headstock 2 that change-speed gearing is equipped with in inside passes through base 20 installations on the ground, in the headstock rear end drive motors 1 is installed, and at the headstock front end main shaft and chuck 3 is installed.Parallel with the main shaft tooth bar tool guide 10 that has is installed on the ground, slip crate 16 and two ram heads 18 and drive motors 15,17 thereof with the tooth bar engaged transmission are installed in the tool guide front, slip crate 12 and two ram heads 14 and drive

motors

11,13 thereof with the tooth bar engaged transmission are installed in the tool guide back.The cross section of described ram is a T shape.On the ground below the main shaft, also be fixed with two the bar shaped platforms 8,9 that have T-slot parallel with main shaft, two static pressure bracing frames 5,7 that support shaft-like workpiece 6 are installed before and after on two bar shaped platforms, the universal joint 4 that connects shaft-like workpiece is installed on chuck.In order to help regulating the bearing height of static pressure bracing frame, bearing 19 is installed below the static pressure bracing frame.Like this, headstock is installed on the ground, the static pressure of workpiece supports on the surface-based bar shaped platform, the height on lathe centre-to-centre spacing ground is reduced greatly, and alleviated the weight of whole lathe greatly, has saved steel; In addition the utility model also have simple in structure, be easy to make, cost is low, the advantage of easy operating.

Claims

1. one kind is landed the combined horizontal lathe, comprise that inside is equipped with the headstock of change-speed gearing, be installed in the drive motors of headstock rear end, be installed in the main shaft and the chuck of headstock front end, the tool guide that have tooth bar parallel with main shaft, be installed on the tool guide and slip crate and knife rest the tooth bar engaged transmission, and drive the motor that slip crate and knife rest move, it is characterized in that: described headstock and tool guide all fix on the ground, on the ground below the main shaft, also be fixed with two the bar shaped platforms that have T-slot parallel with main shaft, two static pressure bracing frames that support shaft-like workpiece are installed before and after on the bar shaped platform, the universal joint that connects shaft-like workpiece is installed on the described chuck.

2. the combined horizontal lathe that lands according to claim 1 is characterized in that: described knife rest both sides are separately installed with T shape ram.
