An automatic fixture for casting and processing of automobile clutch pressure plate

Abstract

The invention discloses an automatic clamp for casting and processing a clutch pressure plate of an automobile, which belongs to the technical field of automobile parts processing. When clamping the clutch pressure plate blank of the automobile, the gear plate can drive four adjusting components to work during rotation, so that the adjusting components drive the positioning block to contact the outer wall of the pressure plate blank. Because the end of the slide seat away from the positioning block is inclined and contacts the inclined surface of one side of the push plate, the push plate can move horizontally in the slideway during the process of the slide seat squeezing the push plate, so that the push plate can squeeze another slide seat, so that the slide seat can slide in the slide hole and drive the positioning block to extend out of the box body. Therefore, when clamping the pressure plate blank at the position of the adjustment box body, the positions of the multiple positioning blocks can be adaptively adjusted according to the geometric shape of the outer wall of the pressure plate blank, so that the positioning blocks can fit tightly with the outside of the pressure plate blank, thereby preventing the force point from being offset and affecting the clamping stability of the pressure plate blank, thereby ensuring the processing accuracy of the pressure plate blank.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention clamps the automobile clutch pressure plate blank, places the pressure plate blank on the table, controls the motor to drive the active gear column to rotate, and the active gear column drives the gear plate to rotate inside the bearing seat through the driven gear column and the supporting shaft seat, and the gear plate is supported and limited by the bearing seat, thereby improving the rotation stability of the gear plate. During the rotation of the gear plate, four adjustment components can be driven to work, so that the adjustment component drives the positioning component to approach the pressure plate blank. When the positioning block in the positioning component contacts the outer wall of the pressure plate blank, the positioning block is pressed to drive the slide seat to slide in the slide hole. Because the slide seat is away from the fixed One end of the positioning block is designed to be inclined and contacts with the inclined surface on one side of the push plate. During the process of the slide squeezing the push plate, the push plate can move horizontally in the slide, so that the push plate can squeeze another slide, so that the slide can slide in the slide hole and drive the positioning block to extend out of the box body. Therefore, when the position of the box body is adjusted to clamp the pressure plate blank, the positions of multiple positioning blocks can be adaptively adjusted according to the geometric shape of the outer wall of the pressure plate blank, so that the positioning block can fit tightly with the outside of the pressure plate blank, preventing the force point from being offset and affecting the clamping stability of the pressure plate blank, thereby ensuring the processing accuracy of the pressure plate blank.

[0015] 2. The present invention drives the toothed disc to rotate. Since the four gears are meshed with the toothed disc, the toothed disc can drive the four gears to rotate synchronously during rotation, and the gears drive the screw rod to rotate. During the rotation of the screw rod, the nut will drive the box body to move on the table through the slide. Since the four box bodies approach or move away from each other synchronously, the positioning components in the box body can approach the pressure plate blank synchronously, and the pressure plate blank can be squeezed by multiple positioning components to be pushed to the center of the table, thereby achieving the purpose of automatic calibration of the pressure plate blank, and the pressure plate blank is locked with the cooperation of multiple positioning blocks to facilitate the subsequent punching and grinding of the pressure plate blank.

[0016] 3. The present invention controls the motor to reverse when the pressure plate blank is removed from the table plate, so that it drives the driven gear column to rotate through the active gear column, and the driven gear column drives the gear plate to reverse through the supporting shaft seat, and the gear plate drives four lead screws to rotate synchronously through four gears, so that the nuts outside the lead screws drive the slide plate away from the table plate, and the slide plate drives the positioning assembly away from the pressure plate blank through the box body. When the positioning block in the positioning assembly gradually moves away from the pressure plate blank, the push plate can be pulled back to the center of the slideway by the action of the first spring on both sides of the first stop block. At the same time, the slide seat is supported by the action of the second spring on the second stop block, so that the slide seat can slide in the slide hole and drive the positioning block back to the initial position. At this time, the ends of the two positioning blocks are in a flush state, which is convenient for the subsequent pressing and positioning work of the pressure plate blank.

[0017] 4. The present invention grinds the surface of the pressure plate blank by loosening the clamping nut, so that the clamping nut moves upward outside the stud, so that the locking state of the pressure plate can be released. When the clamping nut is separated from the top of the stud, the pressure plate can be pulled out upward, and then the stud is rotated in the opposite direction to separate the bottom end of the stud from the middle of the table. Thus, the surface processing of the pressure plate blank is prevented from interfering by removing the limit assembly. When the pressure plate blank is punched, in order to improve the pressure plate blank For vertical stability, place the pressure plate blank on the table, and thread the bottom end of the stud to the middle of the table. Select a pressure plate that is larger than the inner hole diameter of the pressure plate blank and put it on the outside of the stud so that the bottom of the pressure plate contacts the top of the pressure plate blank. Then screw the clamping nut into the stud. When the clamping nut moves downward, it squeezes the pressure plate below so that the pressure plate can fit tightly against the top of the pressure plate blank. The pressure plate blank can be locked in multiple directions to improve the stability of the drilling process of the pressure plate blank. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As a further solution of the present invention, the adjustment assembly 8 includes a gear 801, which is meshed and connected to the toothed disc 702, and the gear 801 is located inside the table 1, and a screw rod 802 is fixedly connected to one side of the gear 801, one end of the screw rod 802 is fixedly installed on the inner wall of the table 1 through a sleeve, and the other end of the screw rod 802 is fixed to one side of the inner wall of the baffle frame 9 through a sleeve, and the screw rod 802 is externally threadedly connected to a nut 803, and the nut 803 is externally fixedly connected to a slide plate 804, and the slide plate 804 is L-shaped and the top is fixed to the bottom of the box body 10; During operation, the four gears 801 are meshed with the toothed disc 702, so that the toothed disc 702 can drive the four gears 801 to rotate synchronously during its rotation, and the gear 801 drives the screw rod 802 to rotate. During the rotation of the screw rod 802, the nut 803 will drive the box body 10 to move on the table 1 through the slide plate 804. Since the four box bodies 10 approach or move away from each other synchronously, the positioning assembly 16 in the box body 10 can approach the pressure plate blank synchronously, and the pressure plate blank is squeezed in multiple directions and pushed to the center of the table 1, thereby achieving the purpose of automatic calibration of the pressure plate blank.

[0026] As a further solution of the present invention, the moving assembly 15 includes a push plate 151, and inclined surfaces are provided on both sides of the push plate 151. The push plate 151 is slidably connected in the slideway 11. The inclined surfaces on both sides of the push plate 151 overlap the ends of the two positioning assemblies 16. A through hole 152 is opened in the middle of the push plate 151. The first stopper 13 is arranged in the through hole 152. The first springs 153 are fixedly connected to the two sides of the first stopper 13, respectively, and the other end of the first spring 153 is fixed to the inner wall of the through hole 152. During operation, when the positioning block 164 in the positioning assembly 16 gradually moves away from the pressure plate blank, the push plate 151 can be pulled back to the center of the slideway 11 through the action of the first springs 153 on both sides of the first stopper 13, so that the positioning assembly 16 can slide in the slide hole 12.

The end of the slide 161 close to the push plate 151 is inclined and overlaps the inclined surface of the push plate 151. A positioning block 164 is fixed to the end of the slide 161 that passes through the slide hole 12. The positioning block 164 is pressed and drives the slide 161 to slide in the slide hole 12. Because the end of the slide 161 away from the positioning block 164 is inclined and contacts the inclined surface of one side of the push plate 151, the push plate 151 can move horizontally in the slideway 11 during the process of the slide 161 squeezing the push plate 151, so that the push plate 151 can squeeze the other slide 161, so that the slide 161 can slide in the slide hole 12 and drive the positioning block 164 to extend out of the box body 10, so that the two positioning blocks 164 on the same box body 10 can be adaptively adjusted according to the shape of the outer wall of the pressure plate blank, effectively achieving the purpose of positioning the pressure plate blank; A recessed hole 162 is provided in the middle of the slide 161, and the second stopper 14 is located in the recessed hole 162.

[0028] As a further solution of the present invention, the limiting assembly 17 includes a stud 171, the bottom end of the stud 171 is threadedly connected to the middle of the platform 1, a pressure plate 173 is connected to the outer surface of the stud 171, the pressure plate 173 is located above the platform 1, a clamping nut 172 is overlapped on the pressure plate 173, and the clamping nut 172 is threadedly connected to the outside of the stud 171; During operation, loosen the clamping nut 172 to make it fall off the stud 171, and take the pressure plate 173 out of the stud 171, then rotate the stud 171 in the opposite direction to disengage the bottom end of the stud 171 from the middle of the table 1, thereby preventing interference with the surface processing of the pressure plate blank by removing the limit assembly 17; thread the bottom end of the stud 171 to the middle of the table 1, select a pressure plate 173 larger than the inner hole diameter of the pressure plate blank and sleeve it on the outside of the stud 171, screw the clamping nut 172 into the stud 171, and the clamping nut 172 moves downward to squeeze the pressure plate 173 below, so that the pressure plate 173 can be close to the top of the pressure plate blank, thereby improving the stability of locking the pressure plate blank.

[0029] As a further solution of the present invention, a fixing frame 4 is fixedly connected to the bottom of the table 1, and the fixing frame 4 is rectangular in design, and mounting plates 5 are fixed around the fixing frame 4, and mounting holes are opened on the mounting plates 5; During operation, the table plate 1 is supported by the rectangular fixing frame 4, thereby improving the stability of the automatic clamp. The mounting plate 5 is matched with the mounting hole setting to facilitate the installation of the automatic clamp on the machine tool table or under the processing equipment, thereby improving the processing stability.

[0030] Working principle of the present invention: When grinding the surface of the pressure plate blank, loosen the clamping nut 172 to move the clamping nut 172 upward outside the stud 171. When the clamping nut 172 is separated from the top of the stud 171, the pressure plate 173 can be pulled out upward. Then, the stud 171 is rotated in the opposite direction to separate the bottom end of the stud 171 from the middle of the table 1. By removing the stopper assembly 17, interference with the surface processing of the pressure plate blank is prevented. When clamping the automobile clutch pressure plate blank, the pressure plate blank is placed on the table 1, and the motor 601 is controlled to work so that it drives the active gear column 602 to rotate. The active gear column 602 drives the toothed disc 702 to rotate inside the bearing seat 701 through the driven gear column 603 and the support shaft seat 604. The four gears 801 are meshed and connected with the toothed disc 702, so that the toothed disc 702 can drive the four gears 801 to rotate synchronously during the rotation of the toothed disc 702, and the gear 801 drives the screw rod 802 to rotate. During the rotation of the screw rod 802, the nut 803 drives the box body 10 to move on the table 1 through the slide plate 804. Because the four box bodies 10 synchronously approach or move away from each other, the positioning assembly 16 in the box body 10 can synchronously approach the pressure plate blank, and the pressure plate blank can be pushed to the center of the table 1, thereby achieving the purpose of automatic calibration of the pressure plate blank; When the positioning block 164 in the positioning assembly 16 contacts the outer wall of the pressure plate blank, the positioning block 164 is pressed to drive the slide 161 to slide in the slide hole 12. Because the end of the slide 161 away from the positioning block 164 is inclined and contacts the inclined surface of one side of the push plate 151, the push plate 151 can move horizontally in the slideway 11 during the process of the slide 161 squeezing the push plate 151, so that the push plate 151 can squeeze another slide 161, so that the slide 161 can slide in the slide hole 12 and drive the positioning block 164 to extend out of the box body 10. Therefore, when the position of the box body 10 is adjusted to clamp the pressure plate blank, the positions of the multiple positioning blocks 164 can be adaptively adjusted according to the geometric shape of the outer wall of the pressure plate blank, so that the positioning blocks 164 can fit tightly with the outside of the pressure plate blank. When punching holes in the platen blank, in order to improve the stability of the platen blank in the vertical direction, the platen blank is placed on the table 1, and the bottom end of the stud 171 is threadedly connected to the middle of the table 1. A platen 173 larger than the inner hole diameter of the platen blank is selected and sleeved outside the stud 171, so that the bottom of the platen 173 contacts the top of the platen blank. Then, the clamping nut 172 is screwed into the stud 171, and the clamping nut 172 moves downward to squeeze the platen 173 below, so that the platen 173 can be tightly attached to the top of the platen blank and limit it. When the pressure plate blank is removed from the table 1, the clamping nut 172 is loosened to make it fall off the stud 171, and the pressure plate 173 is taken out from the stud 171, and the motor 601 is controlled to reverse so that it drives the driven gear column 603 to rotate through the active gear column 602, and the driven gear column 603 drives the gear plate 702 to reverse through the support shaft seat 604, and the gear plate 702 drives the four screw rods 802 to rotate synchronously through the four gears 801, so that the nut 803 outside the screw rod 802 drives the slide plate 804 away from the table 1, and the slide plate 804 is moved through the box The body 10 drives the positioning assembly 16 away from the pressure plate blank. When the positioning block 164 in the positioning assembly 16 gradually moves away from the pressure plate blank, the push plate 151 can be pulled back to the center of the slide 11 through the action of the first springs 153 on both sides of the first stop block 13. At the same time, the slide 161 is supported by the action of the second spring 163 on the second stop block 14, so that the slide 161 can slide in the slide hole 12 and drive the positioning block 164 back to the initial position. At this time, the ends of the two positioning blocks 164 are in a flush state.

[0031] From the above we know: When the position of the box body 10 is adjusted to clamp the platen blank, the positions of the plurality of positioning blocks 164 can be adaptively adjusted according to the geometric shape of the outer wall of the platen blank, so that the positioning blocks 164 can fit tightly with the outer surface of the platen blank, thereby preventing the force point from being offset and affecting the clamping stability of the platen blank, thereby ensuring the processing accuracy of the platen blank; The platen blank is squeezed by multiple positioning assemblies 16, and can be pushed to the center of the platen 1, thereby achieving the purpose of automatic calibration of the platen blank, and the platen blank is locked with multiple positioning blocks 164, so as to facilitate the subsequent punching and grinding of the platen blank; The push plate 151 can be pulled back to the center of the slideway 11 by the action of the first springs 153 on both sides of the first stopper 13. At the same time, the slide seat 161 is supported by the action of the second springs 163 on the second stopper 14, so that the slide seat 161 can slide in the slide hole 12 and drive the positioning block 164 back to the initial position. At this time, the ends of the two positioning blocks 164 are in a flush state, which facilitates the subsequent pressing and positioning of the pressure plate blank. When the surface of the pressure plate blank is ground, the clamping nut 172 is loosened to move the clamping nut 172 upward outside the stud 171, so that the locking state of the pressure plate 173 can be released. When the clamping nut 172 is separated from the top of the stud 171, the pressure plate 173 can be pulled out upward, and then the stud 171 is rotated in the opposite direction to separate the bottom end of the stud 171 from the middle of the table 1. Therefore, by removing the limit assembly 17, interference with the surface processing of the pressure plate blank is prevented; When punching the pressure plate blank, in order to improve the stability of the pressure plate blank in the vertical direction, the pressure plate blank is placed on the table 1, and the bottom end of the stud 171 is threadedly connected to the middle of the table 1, and a pressure plate 173 larger than the inner hole diameter of the pressure plate blank is selected and sleeved on the outside of the stud 171 so that the bottom of the pressure plate 173 contacts the top of the pressure plate blank, and then the clamping nut 172 is screwed into the stud 171. The clamping nut 172 moves downward to squeeze the pressure plate 173 below, so that the pressure plate 173 can be tightly attached to the top of the pressure plate blank, and the pressure plate blank is locked in multiple directions, thereby improving the stability of the drilling process of the pressure plate blank.
