DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an apparatus for performing processing operations such as polishing, grinding, and drilling on the surface of a plate material. More specifically, the present invention relates to an improvement in the drive transmission system of a tool that processes a plate surface while rotating.

[Prior Art] Conventionally, as a plate surface processing apparatus, one shown in FIG. 6, for example, is known.

This conventional machining device consists of a machine tool B having a drive transmission system (not shown) that applies rotational force to the tool A, and a work table on which a plate C, which is the processing material, is installed. A suitable feeding mechanism (not shown) is provided to move the machine tool B in the front, rear, right and left directions of the plate material A as shown by the arrows, and perform a series of continuous or intermittent machining operations on the surface of the plate trA.

It is also known that the feed mechanism is provided on both the work benches of the machine tool 01 or only on the work bench, and various improvements have been attempted depending on the installation space, type of machining, etc.

[Problem J to be solved by the invention In the above-mentioned conventional processing device, in machine tool B, tool A is
The drive transmission system has a meshing structure between gears. Therefore, the following problems arise.

b) Since frictional force is large when gears mesh with each other, wear is high and durability is low.

Mouth) When gears mesh with each other, the frictional force becomes large, so the resistance force is 1.
This results in low drive transmittance.

c) Since gears meshing with each other requires a large installation space, the device becomes larger.

2) Since the engagement between pins requires a large installation space, it is necessary to widen the space between the installed tool tools, which limits the number of tool tools.

In addition to the above-mentioned problems (a) to (c) which are generally disadvantageous to the apparatus, the problem (c) is related to the qualitative and precision aspects of the apparatus, which makes fine machining operations difficult.

The present invention has been made in view of the above-mentioned problems, and its purpose is to improve the drive transmission system so that fine machining operations can be performed using a large number of tools. The goal is to solve the problems of durability, drive force transmission, and larger size.

[Means for solving the gap Z point] The plate surface machining apparatus according to the present invention has a machine tool having a drive transmission system that applies rotational force to the tool, and a work table on which a plate material to be processed is installed. In a sheet processing device that is equipped with a moving feed mechanism and uses this relative movement to perform a series of continuous or intermittent machining operations on the surface of a sheet material, a shaft parallel to the machine tool is used to attach a tool. A drive transmission system consisting of an endless chain meshed and stretched between each coaxially fixed gear and a drive unit such as a motor is provided.
The gears fixed to the shaft are mounted adjacent to each other in phase with each other in the axial direction of the shaft, so that the spacing between the shafts is brought close, and at least two of the chains are meshed and stretched for these phased gears. Adopt means to do so.

[Function] The plate surface processing device according to the present invention aims to reduce frictional force and installation space by meshing gears and chains, and solves the problems of durability, drive transmission performance, and large size. In addition, by adjusting the phase of adjacent gears, the mounting interval of the tool tools can be narrowed, and fine machining operations can be performed using a large number of tool tools.

[Example] Hereinafter, an example of the apparatus for processing plate materials, etc. according to the present invention will be described based on FIGS. 1 to 5.

and a motor 49 connected to the motor 49. The gears 42 fixed to the shaft 41 are adjacent to each other and their positions are out of phase with each other in the axial direction of the shaft 41. Therefore, the spacing between the shafts 41 is reduced so that a large number of shafts 41 can be arranged in parallel in a narrow range.

The phase of this gear 42 matches the fixed interval between two gears 45, 46 on the drive shaft 43 and driven shaft 44, and chains 47, 48 are meshed with and tensioned on each gear.

According to the structure of the drive transmission system 4, when the motor 49 rotates, the polishing tool 2 rotates from the chain 47, 48 through the gear 42 and the shaft 41.
