[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] First, as Figure 1 As shown, a clutch pressure plate processing tool is specifically disclosed, including: a chuck 1, a claw 2 and a clamping device 6. In this embodiment, a plurality of embedded slots are opened on the upper end surface of the chuck 1, and the embedded slots do not penetrate the entire chuck 1, and a claw 2 is arranged in each embedded slot, and the claw 2 can slide relative to the slot to adjust the position.

[0041] like Figure 1 As shown, the claw 2 is stepped as a whole, and a vertically arranged first plane 21 and a first vertical plane 22 are provided on the claw 2, and a second plane 23 is extended from the upper end surface of the first vertical plane 22 in a direction away from the first plane 21, and the length of the first plane 21 is longer than the length of the second plane 23; in this embodiment, the clutch pressure plate 3 to be processed is placed on the first plane 21, and the position of the claw 2 is moved so that the first vertical plane 22 abuts against the pressure plate inner hole of the clutch pressure plate 3. During specific processing, the lower end surface of the clutch pressure plate 3 is placed on the first plane 21, and the relative position of the claw 2 relative to the slot is adjusted so that the first vertical plane 22 abuts against the pressure plate inner hole of the clutch pressure plate 3, thereby realizing the positioning and fixing of the pressure plate inner hole.

[0042] In order to further fix the clutch pressure plate 3, at least one clamping device 6 is provided. The clamping device 6 is installed in the inner hole of the chuck 1 so that it can be clamped on the upper end surface of the clutch pressure plate 3 after installation to ensure that the pressure plate is stable and does not rotate.

[0043] The structure of the clutch pressure plate 3 is as follows: Figure 3 As shown, it can be imagined that the tooling is not limited to the processing of the clutch pressure plate 3, but is also applicable to the processing of similar parts, which are not listed one by one here.

[0044] In the above scheme, the first vertical surface 22 of the claw 2 is in contact with the inner hole of the clutch pressure plate 3, so that the inner hole of the pressure plate can be accurately positioned and fixed; it is helpful to maintain the stability and accuracy of the clutch pressure plate 3 during the processing and improve the processing accuracy; the claw 2 can slide relative to the slot to adjust the position, and can be adjusted and clamped according to the inner hole size of the pressure plate of various models of clutch pressure plates 3 for processing, so that the tooling can be adapted to pressure plates with various inner hole sizes of pressure plates, thereby improving the versatility and flexibility of the tooling and making it more adaptable; the clamping device 6 cooperates with the clamping device 6 to clamp the upper end surface of the clutch pressure plate 3 to jointly fix the position of the clutch pressure plate 3, and the tooling has a simple structure and is easy to operate, thereby improving the processing efficiency.

[0045] In order to realize the sliding of the claw 2 relative to the slot, this embodiment shows a feasible connection method between the claw 2 and the slot. Specifically, convex slideways are provided on both sides of the slot, and correspondingly, concave slideways are provided at the positions corresponding to the slideways on both sides of the claw 2, so that the claw 2 can be slidably connected with the slot of the chuck 1 through the slideway, and can move along the slideway through the slideway to realize the adjustment of the position of the claw 2 to meet the processing requirements of the clutch pressure plate 3 with different inner hole sizes. The matching method of the slideway and the slideway improves the stability of the connection between the claw 2 and the chuck 1.

[0046] In some feasible embodiments, a large annular bevel gear can be provided at the connection between the chuck 1 and the claw 2, the large annular bevel gear is provided on the side away from the claw 2, a flat thread is provided on the side of the large annular bevel gear close to the claw 2, and the large annular bevel gear is connected to the bottom thread of the claw 2. A small bevel gear is provided on the chuck 1 below the large annular bevel gear, the small bevel gear meshes with the large annular bevel gear for transmission, and then the large annular bevel gear can be driven to rotate by driving the small bevel gear to rotate, and the claw 2 is driven to slide relative to the slot through the flat thread.

[0047] like Figure 1 As shown, anti-skid grooves are provided on the first vertical surface 22 abutting against the inner cavity of the clutch pressure plate 3. The setting of the anti-skid grooves increases the contact area between the clutch pressure plate 3 and the first vertical surface 22, thereby increasing the friction force, so that the claws 2 clamp the clutch pressure plate 3 to prevent sliding, which helps to maintain the stability of the clutch pressure plate 3 during the processing, thereby improving the processing accuracy.

[0048] like Figure 1-2As shown, the chuck 1 includes: a first cylindrical platform and a second cylindrical platform, both of which are cylindrical, and the first cylindrical platform and the second cylindrical platform are coaxially arranged, the first cylindrical platform is arranged above the second cylindrical platform, and the diameter of the first cylindrical platform is smaller than the diameter of the second cylindrical platform. When processing the clutch pressure plate 3, the chuck 1 can be directly installed in the machine tool. The arrangement of the first cylindrical platform and the second cylindrical platform on the chuck 1 provides a basis for the installation and arrangement of the claws 2 and the clamping device 6.

[0049] like Figure 2 As shown, in the preferred solution, a positioning pin 5 is also provided on the second cylindrical platform and on the upper end surface perpendicular to the second cylindrical platform. Specifically, a connecting hole for connecting the positioning pin 5 is provided on the upper end surface of the chuck 1, and the positioning pin 5 is directly assembled in the connecting hole; it can be imagined that the opening position of the connecting hole does not conflict with the position of the card slot connecting the claw 2. The opening position of the connecting hole should be such that after the positioning pin 5 is installed, the positioning pin 5 abuts against the side of the protruding part of the clutch pressure plate 3, and then the clutch pressure plate 3 is positioned and fixed by this tooling, which is convenient for the subsequent countersinking and mounting hole 31 processing of the protruding part of the clutch pressure plate 3; the setting of the positioning pin 5 realizes rapid positioning, so that the operator can install the clutch pressure plate 3 more quickly and accurately, further improving the processing efficiency; at the same time, the positioning pin 5 is used as a side direction positioning, so that the protruding part of the clutch pressure plate 3 to be processed is relatively centered, so that the processed hole is also centered, improving the processing accuracy.

[0050] In this embodiment, the embedded card slot is opened on the upper end surface of the first cylindrical platform, that is, the depth of the embedded card slot is the height dimension of the first cylindrical platform. At the same time, a chuck inner hole is also opened through the middle of the first cylindrical platform. The setting of the chuck inner hole provides an installation basis for the subsequent installation of the clamping device 6.

[0051] In this embodiment, a first sensor is also provided at the center of the top of the positioning pin 5, wherein the first sensor can be a beam sensor, and when the tooling is installed on the drilling machine, the first sensor cooperates with the sensor provided on the drilling machine to realize the positioning of the initial installation position of the tooling. Figure 1 As shown, in the present embodiment, the clamping device 6 is overall stepped, and the bottom of the stepped clamping device 6 is installed on the upper end surface of the second cylindrical platform in the inner hole of the chuck, and the side wall of the clamping device 6 facing away from the inner hole of the chuck abuts against the side wall of the inner hole of the chuck. During operation, the upper end surface of the clamping device 6 is arranged to be clamped on the upper end surface of the clutch pressure plate 3, and the clamping device 6 plays a clamping role, so that the clutch pressure plate 3 remains stable and does not rotate under the action of the claw 2 and the clamping device 6.

[0052] like Figure 5As shown, in the present embodiment, a plurality of arcuate plates 7 are installed on the upper end surface of the second cylindrical platform, corresponding to the arcuate outer edge of the protrusion of the clutch pressure plate 3, and the inner diameter of the arcuate plate 7 is equal to or slightly larger than the outer diameter of the protrusion. When the clutch pressure plate 3 to be processed is placed on the tooling, it is only necessary to place the protrusion of the clutch pressure plate 3 corresponding to the arcuate plate 7. During the lowering process, the arcuate outer edge of the protrusion will fall onto the first plane 21 under the guidance of the inner wall of the arcuate plate 7. The placement position of the clutch pressure plate 3 is limited by the arcuate plate 7, so that the placed clutch pressure plate 3 is coaxially arranged with the tooling. Therefore, the clutch pressure plate 3 will not be offset relative to the tooling, which is beneficial for the first vertical surface 22 on each claw 2 to move the same distance when it abuts against the inner hole of the clutch pressure plate 3, thereby clamping the clutch pressure plate 3.

[0053] like Figure 6 As shown, in this embodiment, a collection box 8 is arranged between the first cylindrical platform and each curved plate 7, wherein the two side walls of the collection box 8 respectively match the shapes of the first cylindrical platform and the curved plate 7, so that the two side walls of the collection box 8 are respectively fitted with the side walls of the first cylindrical platform and the curved plate 7. In order to realize the installation of the collection box 8, slide rails are provided on the first cylindrical platform and each curved plate 7, and correspondingly, the two side walls of the collection box 8 are respectively protruded, so that the collection box 8 slides along the slide rails, realizing the sliding connection of the collection box 8 relative to the first cylindrical platform and the curved plate 7.

[0054] In this embodiment, the top of the collecting box 8 is open. Since the collecting box 8 is arranged between the first cylindrical platform and the arc plate 7, and the arc plate 7 is arranged corresponding to the protrusion of the clutch pressure plate 3, when the protrusion of the clutch pressure plate 3 is drilled, the collecting box 8 is just located below the protrusion, and the debris is collected by the collecting box 8.

[0055] Embodiment 1

[0056] A clutch pressure plate processing tooling, comprising: a chuck 1, a claw 2 and a clamping device 6, such as Figure 2 As shown, the upper end surface of the chuck 1 is provided with three embedded slots at uniform angles, the embedded slots do not penetrate the entire chuck 1, and a claw 2 is provided in each embedded slot, and the claw 2 is slidably connected to the slot. The three slots are evenly distributed at angles, so that when the clutch pressure plate 3 is placed and fixed on the claw 2, the clutch pressure plate 3 is evenly stressed.

[0057] A vertically arranged first plane 21 and a first vertical plane 22 are provided on the claw 2. During specific processing, the lower end surface of the clutch pressure plate 3 is placed on the first plane 21, and the position of the claw 2 relative to the slot is adjusted so that the first vertical plane 22 abuts against the inner hole of the clutch pressure plate 3, thereby realizing the positioning and fixation of the inner hole of the clutch pressure plate 3.

[0058] At the same time, a clamping device 6 is installed in the inner hole of the chuck 1, so that the clamping device 6 is pressed against the upper end surface of the clutch pressure plate 3 to keep the clutch pressure plate 3 stable and not rotating.

[0059] Specifically, outwardly convex slideways are provided on both sides of the slot, and correspondingly, inwardly concave slideways are provided at positions corresponding to the slideways on both sides of the claw 2, and the claw 2 is slidably connected to the slot of the chuck 1 via the slideways.

[0060] Specifically, anti-slip grooves are arranged on the first vertical surface 22 abutting against the inner cavity of the clutch pressure plate 3 .

[0061] Specifically, the chuck 1 includes: a first cylindrical platform and a second cylindrical platform, the first cylindrical platform and the second cylindrical platform are coaxially arranged, the first cylindrical platform is arranged above the second cylindrical platform, and the diameter of the first cylindrical platform is smaller than the diameter of the second cylindrical platform.

[0062] Specifically, a positioning pin 5 is also provided on the upper end surface of the second cylindrical platform and perpendicular to the second cylindrical platform. The positioning pin 5 is used as a side direction positioning and abuts against the side of the protruding portion of the clutch pressure plate 3. Embedded card slots are evenly provided on the upper end surface of the first cylindrical platform. The depth of the embedded card slots is the height dimension of the first cylindrical platform, and a chuck inner hole is provided through the middle of the first cylindrical platform. At the same time, a first sensor is also provided at the center position of the top of the positioning pin 5 for positioning the tooling.

[0063] Specifically, the clamping device 6 is of a stepped shape as a whole, and the bottom of the stepped clamping device 6 is installed on the upper end surface of the second cylindrical platform in the inner hole of the chuck, and the side wall of the clamping device 6 facing away from the inner hole of the chuck abuts against the side wall of the inner hole of the chuck. During operation, the upper end surface of the clamping device 6 is arranged to be pressed on the upper end surface of the clutch pressure plate 3 to clamp the clutch pressure plate 3.

[0064] Specifically, three arc-shaped plates 7 are installed on the upper end surface of the second cylindrical platform, corresponding to the arc-shaped outer edge of the protrusion of the clutch pressure plate 3. When the clutch pressure plate 3 is placed on the tooling, the arc-shaped outer edge of the protrusion will be guided by the inner wall of the arc-shaped plate 7 and finally fall to the lower end surface of the clutch pressure plate 3 and be placed on the first plane 21.

[0065] Specifically, a collecting box 8 is disposed between the first cylindrical platform and each arc-shaped plate 7 . The collecting box 8 is located just below the protruding portion, and the debris is collected by the collecting box 8 .

[0066] On the second aspect, a drilling machine is also disclosed, including the above-mentioned clutch pressure plate processing tooling. During the specific processing process, the first cylindrical platform in the clutch pressure plate processing tooling is directly fixedly connected to the drilling machine, and a countersink step drill bit 4 is installed above the corresponding clutch pressure plate processing tooling. The countersink step drill bit 4 is used to realize the processing of the countersink and step hole on the protruding part of the clutch pressure plate 3.

[0067] In the past, the processing flow for this type of parts mostly adopted the following sequence: fine turning of tooth surface - drilling of mounting hole 31 - countersinking - fine turning of plane - balancing. This process has a long processing process, especially for countersinking. The countersinking is processed by ordinary drilling machine. After countersinking, the depth of the countersinking is inconsistent, which poses a quality risk. The assembly is prone to cracking and scrapping. One hole is countersunk at a time, and it takes several rotations to complete the processing, which has low production efficiency. The verticality between the mounting hole 31 and the countersinking is not ideal, the positioning of the parts is inaccurate, and the countersinking has poor bias. The processing flow of the clutch pressure plate 3 by the present clutch pressure plate processing tool is: fine turning of tooth surface - countersinking and drilling of mounting hole 31 - fine turning of plane - balancing, and drilling and countersinking replace the two processes of drilling mounting hole 31 and countersinking in the existing process.

[0068] In the above scheme, the clutch pressure plate 3 is positioned and fixed by the clutch pressure plate processing tooling, and the countersink step drill bit 4 is used to process the countersink and the mounting hole 31 at one time, so that the original multi-step processing is integrated into one step processing, thereby improving efficiency; reducing the thickness difference problem caused by a single countersink and preventing assembly cracking; eliminating accumulated errors, improving product dimensional accuracy, and greatly improving life and appearance; reducing parts processing procedures, improving product qualification rate and production efficiency, and reducing production costs.

[0069] like Figure 1 As shown, in the preferred solution, the countersink step drill bit 4 includes a first drill bit and a second drill bit with different diameters, wherein the first drill bit is used to process the countersink, and the second drill bit is used to process the step hole. The mounting hole 31 and the countersink range 32 are specifically as shown in FIG. Figure 4 As shown, the second drill bit is arranged near the drilling machine when installing. In the present embodiment, the countersink step drill bit 4 is a purchased part, which is not limited here.

[0070] Specifically, the steps for processing the clutch pressure plate 3 by the above-mentioned drilling machine are as follows: install the tooling and set the parameter program of the CNC drilling machine, put the clutch pressure plate 3 on and clamp it through the claws 2, start the equipment, and use the countersink step drill bit 4 to process the countersink and the mounting hole 31 at one time, so that the original multi-step processing is integrated into one step processing, thereby improving efficiency; eliminating accumulated errors, improving product dimensional accuracy, and greatly improving life and appearance; reducing parts processing procedures, improving production efficiency, and reducing production costs.

[0071] In some feasible embodiments, a projection device is also provided on the drilling machine. The projection device projects the size of the tooling that matches the clutch pressure plate 3 to be processed. The operator can directly fix the tooling in the projection area, thereby realizing the rapid positioning of the tooling and preventing the inaccurate drilling position caused by the inaccurate installation position of the tooling. Among them, the projection device can be a projector but is not limited to it. At the same time, a second sensor is also provided on the drilling machine. The second sensor corresponds to the position of the first sensor at the top of the locating pin 5. In this embodiment, the second sensor also adopts a counter-radiation sensor. After the tooling is placed in the projection area, when the first sensor or the second sensor can capture the signal of the other sensor, it means that the installation position of the tooling is accurate, which is conducive to locating the countersink step drill bit 4 to the required processing position.
