[0014] II. The present invention is provided with a fixed adjustment device. The top support seat and the bottom support seat in the fixed adjustment device play a role in limiting the placement of the drum brake pads. The drum brake pads are inserted between the top support seat and the bottom support seat. And the hydraulic cylinder is used to control the sliding adjustment support platform to slide along the track plate. At this time, the support frame and the installation adjustment frame can drive the top support seat, the bottom support seat and the drum brake pads in the middle of the two to move. The moving drum brake pads are guided by the guiding buffer plate so that the outer end of the drum brake pads is in extrusion contact with the outer end of the extrusion partition adjustment plate. Through the limiting extrusion of the extrusion partition adjustment plate, the drum brake pads slide into the interior of the bottom support seat, and the extrusion push plate is extruded to compress the adjustment spring.

[0034] Anti-slip threads are provided inside the extrusion limit groove 15. By screwing the fastening threaded column 14, the front end of the fastening threaded column 14 can stably limit the sliding adjustment plate 16.

[0035] Working principle: First, place the drum brake pads 24 to be cut between the top support seat 25 and the bottom support seat 23 of the fixed adjustment device 4 on the mounting and adjusting frame 6, on the side away from the positioning adjustment device 5. Then start the first motor 10 to drive the drive gear disk 11 to rotate. The rotating drive gear disk 11 drives the rotating adjustment gear disk 9 to rotate by a specified angle, so that the top support seat 25 and the bottom support seat 23 with the drum brake pads 24 placed inside rotate to the side close to the positioning adjustment device 5, and at this time, the bottom support seat 23, the top support seat 25 and the drum brake pads 24 are in a horizontal state (as Figure 1As shown, then start the hydraulic cylinder 1 to drive the sliding adjustment support table 3 to slide forward a specified distance along the track plate 2. At this time, the drum brake pad 24 first contacts the outer wall of the guiding buffer plate 19. Through the buffering and guiding of 19, when the drum brake pad 24 moves to the extrusion partition adjustment plate 13, the outer end of the drum brake pad 24 contacts the outer side end face of the extrusion partition adjustment plate 13. And through the extrusion of the outer side end of the drum brake pad 24 by the extrusion partition adjustment plate 13, the drum brake pad 24 slides along the bottom support seat 23 into the interior of the bottom support seat 23 and compresses the extrusion push plate 30. At this time, when the drum brake pad 24 slides a certain distance along the smooth outer end face of the extrusion partition adjustment plate 13, start the second motor 27 to drive the first driving rod 35 to rotate. Through the first driving rod 35 driven by the second motor 27, the two first driving rods 35 can achieve synchronous rotation through the first adjustment gear 37. The two synchronously rotating first driving rods 35 can drive the second driving rod 36 and the second adjustment gear 38 located outside the first driving rod 35 to rotate respectively through the first driving wheel 32 and the synchronous driving belt 33 by using the second driving wheel 34. The rotating second adjustment gear 38 can then displace the adjustment tooth plate 22 downward. The downward-displaced adjustment tooth plate 22 can then pull the top support seat 25 to squeeze and move towards the bottom support seat 23. At this time, through the top support seat 25 and the bottom support seat 23, the drum brake pad 24 can be squeezed and fixed between the two. Then, through the hydraulic cylinder 1, the sliding adjustment support table 3, the first support frame 12, and the installation adjustment frame 6 slide back to their original positions. And through the first motor 10, the driving gear disk 11 and the rotating adjustment gear disk 9 are driven to rotate a specified angle again. And according to the above steps, the drum brake pads 24 of the same size are firmly clamped between the top support seat 25 and the bottom support seat 23 in each fixed adjustment device 4 on the installation adjustment frame 6. Since the drum brake pads 24 are limited and extruded by the extrusion partition adjustment plates 13 at the same position, the drum brake pads 24 slide between the bottom support seat 23 and the top support seat 25. And the end of the drum brake pad 24 extrudes the extrusion push plate 30 and the adjustment spring 31. Therefore, the sizes of the drum brake pads 24 exposed outside the top support seat 25 and the bottom support seat 23 in each fixed adjustment device 4 are the same. Finally, through the hydraulic cylinder 1, the sliding adjustment support table 3 is pushed to slide along the track plate 2 to the front end of the track plate 2. Use an external cutting device to cut the drum brake pad 24 exposed outside the top support seat 25 along the outer wall of the top support seat 25. In this way, the cut drum brake pad 24 meets the usage specifications and dimensions. And through the rotation of the driving gear disk 11 and the rotating adjustment gear disk 9 driven by the first motor 10, the cutting of the drum brake pads 24 fixed in each fixed adjustment device 4 can be completed, so that the sizes of the drum brake pads 24 remaining inside the top support seat 25 and the bottom support seat 23 after cutting are the same.When the outer extrusion of the drum brake pad 24 by the extrusion partition adjusting plate 13 causes the drum brake pad 24 to slide into the interior of the bottom support seat 23, the friction between the drum brake pad 24 and the bottom support seat 23 can be reduced by the rotating first rotating rod 41 and second rotating rod 44, so that the drum brake pad 24 can smoothly slide into the interior of the bottom support seat 23. And when the top support seat 25 and the bottom support seat 23 are clamped, the first support spring 39 and the second support spring 43 are compressed, so that the support block 40, the first rotating rod 41, the mounting frame 42 and the second rotating rod 44 are contracted into the interior of the bottom support seat 23, thus not affecting the clamping of the drum brake pad 24 by the top support seat 25 and the bottom support seat 23, making the drum brake pad 24 stable and not displaced during the process of cutting the drum brake pad 24 exposed outside the top support seat 25 and the bottom support seat 23. And before cutting the drum brake pad 24, through testing and adjustment, the position of the extrusion partition adjusting plate 13 and the guide buffer plate 19 can be adjusted and controlled by sliding the adjusting plate 16 along the upper end of the second support frame 20, so that the distance of the extrusion partition adjusting plate 13 blocking the drum brake pad 24 and extruding the drum brake pad 24 to slide into the interior of the bottom support seat 23 can be adjusted, so that drum brake pads 24 of various specifications can be processed and cut, and the size specifications of the drum brake pads 24 in the same batch of cutting are the same. During the use of this device, by setting the positioning and adjusting device 5, the guide buffer plate 19 and the extrusion partition adjusting plate 13 in the positioning and adjusting device 5 can play a role of limiting, blocking and adjusting, so that the distance of the drum brake pad 24 exposed outside the top support seat 25 is the same after being blocked, extruded and adjusted by the guide buffer plate 19 and the extrusion partition adjusting plate 13. Thus, the size and specification of the drum brake pad 24 remaining between the top support seat 25 and the bottom support seat 23 after cutting the drum brake pad 24 along the outer wall of the top support seat 25 by an external cutting device are the same, and according to the required cutting size, the position of the extrusion partition adjusting plate 13 can be adjusted to conveniently adjust and control the partial size of the drum brake pad 24 exposed outside the top support seat 25 and the bottom support seat 23. By setting the fixed adjusting device 4, the top support seat 25 and the bottom support seat 23 in the fixed adjusting device 4 play a role of limiting and placing the drum brake pad 24. The drum brake pad 24 is inserted between the top support seat 25 and the bottom support seat 23, and the hydraulic cylinder 1 is used to control the sliding adjustment support platform 3 to slide along the track plate 2. At this time, the first support frame 12 and the mounting and adjusting frame 6 can drive the top support seat 25, the bottom support seat 23 and the drum brake pad 24 in the middle of the two to move. The moving drum brake pad 24 is guided by the guide buffer plate 19 so that the outer end of the drum brake pad 24 is in extrusion contact with the outer end of the extrusion partition adjusting plate 13.Through the limit extrusion of the extrusion partition adjusting plate 13, the drum brake pad 24 slides into the interior of the bottom support seat 23, and the extrusion push plate 30 is extruded to compress the adjusting spring 31. When the drum brake pad 24 slides a certain distance along the extrusion partition adjusting plate 13, it is clamped between the top support seat 25 and the bottom support seat 23 through the top support seat 25 firmly, so that the drum brake pad 24 is fixed between the top support seat 25 and the bottom support seat 23, facilitating the external cutting device to cut the drum brake pad 24 exposed outside the top support seat 25 along the outer end of the top support seat 25, making the sizes of the drum brake pads 24 produced by cutting through the control of this device the same, and the cutting size is convenient to adjust and control. This device can be conveniently and quickly controlled and adjusted, so that the sizes of the drum brake pads 24 produced by cutting and processing in the same batch are the same.
