Description

Technical Field

[0001] The utility model relates to the technical field of motor stator sheet production equipment, in particular to a motor stator sheet stamping device which is convenient for replacing a stamping disk. Background Art

[0002] Motor stator laminations are key components of motors. Their material, inner and outer dimensions, and slot size have a direct impact on the motor's energy consumption, operating efficiency, noise, and service life. Motor stator laminations are manufactured using a stamping machine.

[0003] An existing generator stator sector punching device (Announcement No.: CN219309918U) has at least the following disadvantages: the device directly fixes the stamping plate to the cylinder, resulting in the inability to replace it when different models of motor stator plates need to be stamped. The existing technology also uses bolts to install the stamping plate. Although the stamping plate can be replaced, the upper and lower stamping plates need to be plugged together during the installation process, and then the lifting plate is driven to press the upper stamping plate and then the upper and lower stamping plates are fixed with bolts respectively. Since the gap between the lifting plate and the workbench is small and inconvenient to operate, and the installation speed of bolts is slow, the installation process of the stamping plate is relatively cumbersome and inconvenient, and it is time-consuming, which affects the production speed of the stator plates. For this reason, the present utility model is proposed. Utility Model Content

[0022] like Figures 1-4As shown, a motor stator sheet stamping device which is convenient for replacing the stamping disk comprises a workbench 1, wherein a top frame 101 is fixed to the top surface of the workbench 1, a first hydraulic rod 102 is fixed to the top surface of the top frame 101, one end of the telescopic rod of the first hydraulic rod 102 extends through the bottom surface of the top frame 101, a lifting plate 103 is fixed to one end of the telescopic rod of the first hydraulic rod 102, an upper pressure plate 104 is arranged on the bottom surface of the lifting plate 103, a lower pressure plate 105 is arranged on the top surface of the workbench 1, and disassembly and assembly components are arranged on both sides of the workbench 1 close to the lifting plate 103, the disassembly and assembly components include a lower fixed bar 2 fixed to the top surface of the workbench 1, an upper fixed bar 201 is fixed to the bottom surface of the lifting plate 103 at a position corresponding to the lower fixed bar 2, and a lower movable clamping bar 202 and an upper movable clamping bar 203 are respectively arranged on both sides of the workbench 1 close to the lifting plate 103.

[0023] like Figure 2-Figure 4 As shown, in this embodiment, the left and right sides of the outer walls of the upper and lower pressure plates 104 and the lower pressure plate 105 are welded and fixed with matching blocks 204, and the two sides close to the workbench 1 and the lifting plate 103 are fixed with second hydraulic rods 205. One end of the telescopic rod of the second hydraulic rod 205 of the workbench 1 is fixed to one side of the lower movable clamping bar 202, and one end of the telescopic rod of the second hydraulic rod 205 of the lifting plate 103 is in contact with one side of the upper movable clamping bar 203. A positioning pin 206 is fixed to the bottom surface of the upper movable clamping bar 203, and a positioning groove 207 is provided on the top surface of the lower movable clamping bar 202 to the corresponding position of the positioning pin 206. By adopting the internal plugging of the positioning pin 206 and the positioning groove 207, the upper movable clamping bar 203 and the lower movable clamping bar 202 are kept in linkage during installation. In this process, the upper and lower pressure plates 104 and 105 are connected. The upper and lower pressure plates 104 and 105 are in a synchronous movement state. At the same time, the upper movable clamping bar 203 also moves synchronously with the lower movable clamping bar 202. When the lower pressure plate 105 is clamped and fixed by the lower movable clamping bar 202 and the lower fixed bar 2, the upper movable clamping bar 203 and the upper fixed bar 201 also happen to clamp and fix the upper pressure plate 104, ensuring that the upper pressure plate 104 and the lower pressure plate 105 are accurately aligned. At this time, the second hydraulic rod 205 is activated to abut and fix the position of the upper movable clamping bar 203, thereby ensuring that when the lower movable clamping bar 202 and the upper movable clamping bar 203 are separated, the upper pressure plate 104 is still stably clamped and fixed.

[0024] like Figure 2-Figure 4As shown, in this embodiment, the lower fixed bar 2, the upper fixed bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203 are all inclined structures with equal slopes on both sides close to the corresponding matching blocks 204, wherein the inclined surfaces of the lower fixed bar 2 and the lower movable clamping bar 202 are upward, and the corresponding matching blocks 204 are inclined downward, and the inclined surfaces of the upper fixed bar 201 and the upper movable clamping bar 203 are downward, and the corresponding matching blocks 204 are inclined upward. By setting the lower fixed bar 2, the upper fixed bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203, the inclined surfaces of the lower fixed bar 201 and the upper movable clamping bar 203 are downward, and the corresponding matching blocks 204 are inclined upward. The two sides where 202 and the upper movable clamp 203 are close to the corresponding matching block 204 are all inclined structures with equal slopes, so that when the lower fixed bar 2, the upper fixed bar 201, the lower movable clamp 202 and the upper movable clamp 203 are in contact with the corresponding matching block 204, an extrusion force is applied to the matching block 204 toward the workbench 1 or the lifting plate 103, so that the upper pressure plate 104 and the lower pressure plate 105 are tightly fitted with the workbench 1 or the lifting plate 103, ensuring the stability of the upper pressure plate 104 and the lower pressure plate 105 after installation.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, sliding grooves 3 are provided on both sides of the workbench 1 and the lifting plate 103, and the lower movable clamp 202 and the upper movable clamp 203 are respectively set to slide inside the two sliding grooves 3. By setting the lower movable clamp 202 and the upper movable clamp 203 to slide inside the two sliding grooves 3 respectively, the supporting strength of the lower movable clamp 202 and the upper movable clamp 203 is increased to ensure better compression fitting of the block 204.

[0026] like Figure 2-Figure 4 As shown, in this embodiment, the workbench 1 and the lifting plate 103 are respectively fixed with a limiting rod 4 and a limiting cylinder 401 on both sides thereof, the limiting rod 4 and the limiting cylinder 401 are internally slidingly arranged, and the outer wall of the limiting rod 4 is movably sleeved with a buffer spring 402, and the top and bottom ends of the buffer spring 402 are respectively in contact with the bottom end of the limiting cylinder 401 and the top surface of the end of the limiting rod 4, and the internal sliding arrangement of the limiting rod 4 and the limiting cylinder 401 can play a role in limiting and supporting the lifting of the lifting plate 103, and the buffer spring 402 can play a buffering role when the lifting plate 103 is lowered for stamping.

[0027] like Figure 2-Figure 4 As shown, in this embodiment, a plurality of anti-slip grooves 5 are provided on the inclined side of the mating block 204. Through the setting of the anti-slip grooves 5, the friction force when the mating block 204 abuts against the lower fixed bar 2, the upper fixed bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203 can be reduced, thereby ensuring the stability of the installation of the upper pressure plate 104 and the lower pressure plate 105.

[0028] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: in use, the upper pressure plate 104 and the lower pressure plate 105, which are connected together by a slight groove, are placed together on the top surface of the workbench 1, and then the first hydraulic rod 102 is started to drive the lifting plate 103 to fit the upper pressure plate 104. At this time, the positioning slight 206 is plugged into the inside of the positioning groove 207, so that the upper movable clamping strip 203 and the lower movable clamping strip 202 are kept in linkage during installation, and then the second hydraulic rod 205 on the workbench 1 is started to drive the lower movable clamping strip 202 to abut against the matching block 204 of the lower pressure plate 105, and push the lower pressure plate 105 to move The upper movable clamping bar 203 pushes the upper pressure plate 104 to move until the lower pressure plate 105 is away from the matching block 204 of the lower movable clamping bar 202 and abuts against the lower fixed bar 2, thereby clamping and fixing the lower pressure plate 105. At this time, the upper pressure plate 104 is clamped and fixed synchronously, and then the second hydraulic rod 205 of the lifting plate 103 is started to abut tightly against one side of the upper movable clamping bar 203. Then the installation of the upper pressure plate 104 and the lower pressure plate 105 can be completed. At this time, the first hydraulic rod 102 is started again to drive the lifting plate 103 to rise, so that the upper pressure plate 104 and the lower pressure plate 105 are separated, and the stamping operation of the motor stator can be started. The lower fixing bar 2, the upper fixing bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203 are all inclined structures on both sides close to the corresponding matching block 204, so that when the lower fixing bar 2, the upper fixing bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203 are in contact with the corresponding matching block 204, an extrusion force is applied to the matching block 204 toward the workbench 1 or the lifting plate 103, so that the upper pressure plate 104 and the lower pressure plate 105 are closely in contact with the workbench 1 or the lifting plate 103, ensuring the stability of the upper pressure plate 104 and the lower pressure plate 105 after installation. The internal sliding setting of the two sliding grooves 3 increases the supporting strength of the lower movable clamping bar 202 and the upper movable clamping bar 203 to ensure better compression of the matching block 204. The internal sliding setting of the limiting rod 4 and the limiting cylinder 401 can play a limiting and supporting role in the lifting and lowering of the lifting plate 103. The buffer spring 402 can play a buffering role when the lifting plate 103 is lowered for stamping. Through the setting of the anti-slip groove 5, the friction force when the matching block 204 and the lower fixed bar 2, the upper fixed bar 201, the lower movable clamping bar 202 and the upper movable clamping bar 203 are abutted can ensure the stability of the installation of the upper pressure plate 104 and the lower pressure plate 105.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
