Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coating fixture, and particularly relates to a gasket end face coating tool. BACKGROUND

[0002] As a sealing element needed when various devices are connected, the gasket needs to have high hardness and corrosion resistance. With the development of industrial technology and the improvement of product performance requirements, the performance requirements for gaskets are becoming higher and higher. The surface heat treatment process cannot meet the service life requirements of some devices. Therefore, some existing technologies use coating technology to improve the service life of the gasket.

[0003] Because the size of the gasket is generally small, and the one-time production quantity of the gasket is relatively large, the existing coating fixture cannot clamp too many gaskets at one time, and the clamping tightness of the gasket is uneven, which leads to poor coating quality of the gasket and low coating efficiency. Therefore, the present application aims to design a tool clamp that can clamp more gaskets at one time and has high clamping tightness to solve the problems existing in the prior art. SUMMARY

[0004] In view of the problem of loose clamping and inability to clamp a large number of workpieces at one time in the prior art, the utility model provides a gasket end face coating tool to solve the above problems.

[0005] The utility model provides a gasket end face coating tool, which comprises a clamp body and a plurality of workpieces, the upper surface of the clamp body is provided with a workpiece groove for placing the workpieces, the workpiece grooves are arranged along the direction of the two ends of the clamp body, and the workpiece grooves are mirror images based on the central axis surface of the two end directions of the clamp body; the upper surface of the clamp body is also provided with a clamping piece groove based on the central axis surface, the clamping piece groove is located on the side away from the central axis surface of the workpiece groove, and the clamping piece groove is connected with the workpiece groove; a clamping piece is embedded in the clamping piece groove, and a pressing bolt penetrates the side surface of the clamp body perpendicularly; the pressing bolt pushes the clamping piece towards the central axis surface to press the workpiece.

[0006] By adopting the above technical scheme, the workpieces are placed one by one corresponding to the workpiece grooves, so that part of the workpieces can be located in the clamping piece groove. At this time, the pressing bolt is rotated, the pressing bolt penetrates the side surface of the clamp body and abuts against the clamping piece, and then the clamping piece is pushed to move towards the workpiece direction. The clamping piece is attached to one side of the workpiece, and the workpiece is pressed towards the workpiece groove. One clamp body can clamp multiple workpieces, ensuring the stability of clamping and improving the efficiency of coating.

[0007] In a specific embodiment, the position where the workpiece groove is connected with the clamping piece groove is provided with a communication port, and the edge of the workpiece extends into the clamping piece groove from the communication port.

[0008] By adopting the technical scheme, a part of the workpiece can enter the range of the clamping sheet groove from the position of the communication opening, so that the clamping sheet can be in contact with the side surface of the workpiece and press the workpiece to the other side of the workpiece groove.

[0009] In specific embodiments, the sum of the width of the workpiece extending into the clamping sheet groove and the thickness of the clamping sheet is less than or equal to the width of the clamping sheet groove.

[0010] By adopting the technical scheme, the size of the workpiece after being attached to the clamping sheet can be adapted to the size of the clamping sheet groove. When the total size of the two is less than the size of the clamping sheet groove, a certain movement space can be given to the clamping sheet, and the position of the clamping sheet can be fine-tuned before the tightening bolt is tightened. At the same time, the workpiece is also easier to place into the workpiece groove and will not be blocked by the clamping sheet during placement.

[0011] In specific embodiments, the workpiece is a round sheet, the workpiece groove is a circular recess, and the depth of the workpiece groove is the same as the thickness of the workpiece. The workpiece is embedded in the workpiece groove.

Within a certain length-width range, as many workpieces as possible can be arranged for plating to improve plating efficiency.

[0013] In specific embodiments, the clamping sheet groove is a rectangular recess, and the clamping sheet groove extends along the direction of the two ends of the clamp body. The workpiece grooves on the same side are connected in sequence with the clamping sheet groove.

[0014] By adopting the technical scheme, one rectangular clamping sheet groove is arranged on the outer side of each of the two rows of workpiece grooves. One clamping sheet groove can connect all the workpiece grooves in the same row, and there is no need to set a separate clamping sheet groove for each workpiece groove, which simplifies the operation when the workpiece is clamped, but does not affect the clamping effect.

[0015] In specific embodiments, the depth of the clamping sheet groove is greater than the depth of the workpiece groove, and the depth of the clamping sheet groove is greater than one-half of the thickness of the clamp body.

[0016] By adopting the technical scheme, the depth of the clamping sheet groove ensures that the clamping sheet will not come out of the clamping sheet groove when it is pressed, and the clamping sheet can cover the thickness range of the workpiece, avoiding the situation that the clamping sheet only presses the lower half of the workpiece, causing the workpiece to be unevenly stressed and come out of the workpiece groove.

[0017] In specific embodiments, the two side surfaces of the clamp body parallel to the central axis surface are provided with a plurality of pressing screw holes, the pressing screw holes are communicated with the clamping sheet groove, and the pressing screw is threadedly connected with the pressing screw hole.

[0018] By adopting the technical scheme, the clamping pieces are pressed towards the workpieces by the plurality of pressing bolts, so that the distribution of the pressing force is more uniform, and the situation that the workpieces at different positions are not pressed tightly or are separated from the workpiece grooves due to uneven force is avoided.

[0019] In specific embodiments, the number of the pressing screw holes is the same as the number of the workpiece grooves, and the positions of the pressing screw holes correspond to the positions of the workpiece grooves.

[0020] By adopting the technical scheme, the pressing force of each workpiece can be adjusted by the corresponding pressing bolt, so that the operation is more flexible during clamping, and the pressing force of each workpiece is adjusted to be optimal.

[0021] In specific embodiments, the diameter of the pressing screw hole is smaller than the depth of the clamping piece groove, and is greater than two-thirds of the depth of the clamping piece groove, and the center of the pressing screw hole is located on the one-half depth level of the clamping piece groove.

[0022] By adopting the technical scheme, the cross section of the pressing screw hole can be evenly distributed on the upper and lower parts of the clamping piece, so that the pressing force received by each workpiece groove is not uneven, and the clamping effect of the workpiece is further improved.

[0023] In specific embodiments, the upper surface of the clamp body is also provided with a penetrating mounting screw hole, the center of the mounting screw hole is located on the central axis plane, and the mounting screw hole is located at the two end positions of the clamp body.

[0024] By adopting the technical scheme, the mounting screw hole can be matched with the platform of the coating equipment, and the mounting screw hole is arranged at the two ends of the central axis plane, so that the available area of the clamp body is improved, the matching of the clamp body and the coating equipment is more simple, and the installation efficiency is improved.
