Description

Technical Field

[0001] The utility model relates to the relevant field of tool processing, in particular to a tool coating clamping component. Background Art

[0002] By forming a certain thin film on the surface of the tool by chemical or physical methods (i.e. coating process), the cutting tool can obtain excellent comprehensive cutting performance, thereby meeting the requirements of high-speed cutting processing; since the advent of hard-coated tools, chemical vapor deposition (CVD) technology and physical vapor deposition (PVD) technology have been developed successively, opening a new chapter in history for the improvement of tool performance.

[0003] The purpose of coating the tool is not only to increase the wear resistance life, but also to improve the friction reduction performance, so as to achieve the purpose of improving machining accuracy, reducing the surface roughness of the workpiece, and not adding cutting fluid or adding less cutting fluid when the tool is cutting. On the other hand, good friction reduction and less heat generation of the tool cutting edge also play a role in extending the life. Coated tools can greatly increase the life of cutting tools; effectively improve machining efficiency and machining accuracy and significantly improve the surface quality of the workpiece being machined; effectively reduce the consumption of tool materials and reduce machining costs.

[0004] Many tool clamping devices only provide clamping function when clamping cylindrical tools for coating. However, the cutting surface of cylindrical tools is relatively irregular. When coating, it is difficult to fully and evenly adhere the coating to the cutting surface by simply moving the clamping assembly driven by the coating device, which increases the tool defect rate. Utility Model Content

[0005] The purpose of the utility model is to provide a tool coating clamping assembly to solve the problem that the tool clamping device proposed in the above background technology mainly only provides a clamping function when clamping a cylindrical tool for coating, and the cutting surface of the cylindrical tool is relatively irregular. When coating, the coating is only driven by the coating device to drive the clamping assembly to move simply, and it is difficult to fully and evenly adhere to the cutting surface coating, resulting in an increased tool defect rate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool coating clamping assembly, including a clamping unit, a plurality of clamping units are provided, and two clamping bodies are symmetrically arranged on the clamping unit, and the clamping body includes a connecting vertical plate, a first adjusting member is provided at the front end of the inner side of the connecting vertical plate, and a second adjusting member is provided at the rear end of the inner side of the connecting vertical plate, and the first supporting plate, the second supporting plate and the third supporting plate are both provided on the first adjusting member and the second adjusting member, and are welded and fixed to the connecting vertical plate, and the first supporting plate, the second supporting plate and the third supporting plate are arranged from top to bottom, and a rotating roller is rotatably connected to the inner side between the second supporting plate and the third supporting plate, and a clamping interval is formed between the two rotating rollers on each side.

[0007] Preferably, a transmission wheel is provided between the second support plate and the third support plate, the transmission wheel is coaxially connected to the rotating roller at its lower end, and the two transmission wheels are connected by a transmission belt.

[0008] Preferably, the clamping unit further comprises a fixing plate, and a driving cylinder is installed in the middle of the lower end of the fixing plate.

[0009] Preferably, a driving movable plate is fixed to the output rod end of the driving cylinder, and a first fixed seat is welded and fixed on both sides of the driving movable plate. A clamping action rod is connected to the first fixed seat through an axial rotation, and the other end of the clamping action rod is fixed to a vertical plate connected to the clamping body.

[0010] Preferably, fixed uprights are welded and fixed on both sides of the lower end of the fixed plate, the lower ends of the fixed uprights are integrally connected with a second fixed seat, a side fixed seat is fixed in the middle of the outer side of the clamping action rod, the side fixed seat extends into the second fixed seat and is rotatably connected to the second fixed seat through an axis.

[0011] Preferably, a plurality of upper fixing plates of the clamping units are fixed at equal distances to the upper end surface inside the supporting C-shaped plate, and mounting C-shaped plates are welded and fixed on both sides of the upper end of the supporting C-shaped plate.

[0012] Preferably, a driving motor is installed on the upper end of the first supporting plate on the first adjusting member, and the output shaft end of the driving motor passes through the first supporting plate on the first adjusting member and is connected to the transmission wheel on the first adjusting member.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a driving motor drives the transmission wheel connected thereto to rotate, and the rotating roller is driven to rotate through the transmission relationship between the transmission wheel and the transmission belt and the coaxial connection relationship between the transmission wheel and the rotating roller. The four rotating rollers on each group of clamping units rotate synchronously in the same direction, so that the tool to be coated is rotated in a fixed position state, which is more convenient for uniform coating. This solves the problem that the current tool clamping device mainly only provides a clamping function when clamping a cylindrical tool for coating, while the cutting surface of the cylindrical tool is relatively irregular. When coating, the coating is only driven by the simple movement of the clamping component driven by the coating device, and the cutting surface coating is difficult to be fully and evenly adhered, resulting in an increase in the tool defect rate.

[0015] 2. In the utility model, the output rod end of the driving cylinder contracts and drives the driving movable plate to move upward. Since one end of the clamping action rod is rotatably connected to the first fixed seat through an axis, and the side fixed seat fixed on the outside of the clamping action rod is rotatably connected to the second fixed seat in a fixed position through an axis, the upward movement of the movable plate will drive the clamping body to rotate inward, and fix the upper end position of the tool to be coated in the space between the two clamping intervals, which can effectively clamp and fix the tool, and at the same time cooperate to complete the rotation drive work of the tool, and the auxiliary cooperation improves the coating efficiency.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-4 The utility model provides an embodiment: a tool coating clamping assembly, including a clamping unit 3, wherein the clamping unit 3 is provided with a plurality of fixing plates 4 on the plurality of clamping units 3 are equidistantly fixed to the upper end surface of the inner part of the supporting C-shaped plate 2, and the two sides of the upper end of the supporting C-shaped plate 2 are welded and fixed with mounting C-shaped plates 1.

[0023] The clamping unit 3 is symmetrically provided with two clamping bodies 9, the clamping body 9 includes a connecting plate 13, a first adjusting member 14 is provided at the front end of the inner side of the connecting plate 13, and a second adjusting member 15 is provided at the rear end of the inner side of the connecting plate 13. The first adjusting member 14 and the second adjusting member 15 have the same structure and size, and only the driving structure is different. The first adjusting member 14 and the second adjusting member 15 are both provided with a first supporting plate 16, a second supporting plate 17 and a third supporting plate 18 which are welded and fixed to the connecting plate 13. The first supporting plate 16, the second supporting plate 17 and the third supporting plate 18 are welded and fixed to the connecting plate 13. The support plate 17 and the third support plate 18 are arranged from top to bottom, and the inner side between the second support plate 17 and the third support plate 18 is rotatably connected with a rotating roller 19. In order to avoid wear and damage to the outer upper end part of the tool and increase the clamping effect of the outer upper end part of the tool, a rubber layer is arranged on the outside of the rotating roller 19, and the outer surface of the rubber layer is provided with anti-slip grooves. A clamping interval 20 is formed between the two rotating rollers 19 on each side, and a part of the outer upper end part of the tool is located in the clamping interval 20, and can be driven to rotate by the rotation of the rotating roller 19.

[0024] The clamping unit 3 also includes a fixed plate 4, and a driving cylinder 5 is installed in the middle of the lower end of the fixed plate 4. The driving cylinder 5 can also be other driving and adjusting structures. The output rod end of the driving cylinder 5 is fixed with a driving movable plate 6, and the first fixed seat 7 is welded and fixed on both sides of the driving movable plate 6. A clamping action rod 8 is connected to the first fixed seat 7 through an axial rotation. The other end of the clamping action rod 8 is fixed to a connecting plate 13 on the clamping body 9. Fixed vertical rods 10 are welded and fixed on both sides of the lower end of the fixed plate 4. The lower end of the fixed vertical rod 10 is integrally connected with a second fixed seat 11.

[0025] The clamping assembly is installed at the driving end of the coating device by installing the C-shaped plate 1 to play a connecting role.

[0026] The upper end of the tool to be coated is placed between the two clamping bodies 9 of each clamping unit 3; the output rod end of the driving cylinder 5 contracts and drives the driving movable plate 6 to move upward. Since one end of the clamping action rod 8 is connected to the first fixed seat 7 by an axial rotation, and the side fixed seat 12 fixed on the outside of the clamping action rod 8 is connected to the second fixed seat 11 at the fixed position by an axial rotation, the driving movable plate 6 moves upward and drives the clamping body 9 to rotate inward, thereby fixing the upper end of the tool to be coated in the space between the two clamping sections 20.

[0027] Furthermore, a transmission wheel 21 is arranged between the second support plate 17 and the third support plate 18, and the transmission wheel 21 is coaxially connected to the rotating roller 19 at its lower end.

[0028] The diameter of the transmission wheel 21 is smaller than the diameter of the rotating roller 19 to avoid hindering the driven rotation state of the outer upper end portion of the tool.

[0029] When coating is performed, the driving motor 23 drives the transmission wheel 21 connected thereto to rotate, and the rotating roller 19 is driven to rotate through the transmission relationship between the transmission wheel 21 and the transmission belt 22 and the coaxial connection relationship between the transmission wheel 21 and the rotating roller 19. The four rotating rollers 19 on each group of clamping units 3 rotate synchronously in the same direction, so that the tool to be coated rotates in a fixed position to cooperate with the coating operation.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
