Description

Technical Field

[0001] The utility model relates to the technical field of pressing plate mechanisms, in particular to a new pressing plate mechanism. Background Art

[0002] The pressure plate mechanism is a mechanical device used to clamp workpieces. It is widely used in processing, assembly and handling processes. It fixes the workpiece in the desired position by applying pressure to ensure the accuracy and stability of the process.

[0003] A Chinese patent, publication number CN210189114U, discloses a nut-removable pressure plate mechanism. The key technical features of the mechanism are: a pressure plate, a bolt, and a nut screwed onto the bolt. The bolt has a T-shaped block head and a connected screw rod. The pressure plate has a strip-shaped through-hole for the screw rod to pass through. The pressure plate also has a cylindrical through-hole for the nut to pass through, which is connected to the strip-shaped through-hole in the pressure plate. With this invention, when the bolt needs to be replaced, one only needs to loosen the nut and move the pressure plate so that the screw rod is located in the cylindrical through-hole in the pressure plate. The pressure plate can then be removed and the bolt replaced without removing the nut.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using a pressure plate mechanism to fix workpieces of different sizes, workers need to replace different shims, which wastes working time and easily reduces overall work efficiency.

[0005] Therefore, the utility model provides a new pressing plate mechanism. Utility Model Content

[0008] The effect achieved by the above components is: by setting up a support structure, workers do not need to replace different shims when using a pressure plate mechanism to fix the workpiece, reducing the demand for different shims and thus improving overall work efficiency.

[0011] Preferably, a connection pad is fixedly mounted on the surface of the baffle, and the surface of the connection pad is slidably connected to the pressure plate body.

[0012] The effect achieved by the above components is that the connection pad prevents the baffle from rotating during the sliding process of the baffle.

[0013] Preferably, a clamping column is fixedly inserted into the interior of the pressure plate body, and a clamping groove is opened on the surface of the baffle, and the inner wall of the clamping groove abuts against the clamping column.

[0014] The effect achieved by the above components is that when the hanging block slides in the direction away from the limit plate, the hanging block stops sliding when the inner wall of the clamping groove on the hanging block abuts against the surface of the clamping column.

[0015] Preferably, a hanging block is fixedly mounted on the surface of the baffle, and the cross section of the hanging block is "L"-shaped.

[0016] The effect achieved by the above components is: when the hanging block is rotated to a certain angle, the surface of the hanging block contacts the limit plate. At this time, the baffle cannot slide toward the limit plate due to the obstruction of the hanging block.

[0030] Reference Figure 1 As shown, the utility model provides a technical solution: a new pressure plate mechanism, including a clamping block 1 and a stop block 501, a screw rod 2 is fixedly inserted inside the clamping block 1, a nut 3 is threadedly connected to the arc surface of the screw rod 2, a pressure plate body 4 is sleeved on the arc surface of the screw rod 2, and a support structure 5 is provided on the surface of the pressure plate body 4. By setting the support structure 5, the staff does not need to replace different shims when fixing the workpiece using the pressure plate mechanism, reducing the demand for different shims, thereby improving the overall work efficiency, and an auxiliary structure 6 is provided on the surface of the stop block 501. By setting the auxiliary structure 6, the contact area between the support structure 5 and the screw rod 2 can be increased, and the auxiliary support structure 5 is supported on the screw rod 2, thereby improving the stability of the support structure 5.

[0031] The specific configuration and functions of the supporting structure 5 and the auxiliary structure 6 will be described in detail below.

[0032] Reference Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment: the support structure 5 includes a bearing rod 504, which is slidably inserted into the interior of the pressure plate body 4, and a connecting block 502 is fixedly installed on the surface of the bearing rod 504, and a stop block 501 is fixedly installed on the surface of the connecting block 502, and the surface of the stop block 501 abuts against the screw 2. A limit plate 503 is fixedly installed on the surface of the pressure plate body 4, and a cross bar 505 is fixedly inserted into the interior of the limit plate 503, and a hanging block 508 is slidably sleeved on the circular arc surface of the cross bar 505, and a spring 506 is sleeved on the circular arc surface of the cross bar 505, and the two ends of the spring 506 are fixedly connected to the baffle 509 and the limiting plate 503 respectively. A rectangular groove 507 is opened on the surface of the bearing rod 504, and the inner wall of the rectangular groove 507 is slidably connected to the hanging block 508. The hanging block 508 can clamp the bearing rod 504 inside the pressure plate body 4, thereby achieving the effect of fixing the bearing rod 504 and the pressure plate body 4. A connection pad 510 is fixedly mounted on the surface of the baffle 509. The surface of the connection pad 510 is slidably connected to the pressure plate body 4. The connection pad 510 prevents the baffle 509 from rotating during its sliding process. A fixed post 511 is inserted into the interior of the pressure plate body 4. A slot 512 is formed on the surface of the baffle 509. The inner wall of the slot 512 abuts against the post 511. When the hanging block 508 slides away from the limit plate 503, the hanging block 508 stops sliding when the inner wall of the slot 512 on the hanging block 508 abuts against the surface of the post 511. The hanging block 508 is fixedly mounted on the surface of the baffle 509. The cross-section of the hanging block 508 is "L" shaped. When the hanging block 508 is rotated to a certain angle, the surface of the hanging block 508 contacts the limit plate 503. At this time, the baffle 509 cannot slide toward the limit plate 503 due to the obstruction of the hanging block 508.

[0033] Reference Figure 3 and Figure 5 As shown, specifically, the auxiliary structure 6 includes two lifting rods 61, which are respectively slidably inserted into the interior of the block 501. Auxiliary blocks 62 are fixedly installed on the surfaces of the two lifting rods 61, and the surfaces of the auxiliary blocks 62 abut against the screw 2. A plug pad 63 is fixedly installed on the surface of the block 501. The plug pad 63 is an elastic pad. A rectangular hole 64 is opened on the surface of the auxiliary block 62. The size of the rectangular hole 64 is adapted to the size of the plug pad 63. After the auxiliary block 62 slides upward and slides a certain distance under the support of the lifting rod 61, the plug pad 63 on the block 501 is inserted into the inner wall of the rectangular hole 64. At this time, the plug pad 63 is stuck on the inner wall of the rectangular hole 64 by elastic force. At this time, the block 501 and the auxiliary block 62 are fixed, achieving the effect of fixing the block 501 and the auxiliary block 62.

[0034] Working principle: when the pressure plate structure needs to be used to fix the workpiece, first pull the baffle 509 to let the baffle 509 slide in the direction close to the limit plate 503. After the baffle 509 slides a certain distance, stop pulling the baffle 509, and then rotate the hanging block 508. After the hanging block 508 rotates a certain angle, the surface of the hanging block 508 contacts the limit plate 503. At this time, the baffle 509 cannot slide in the direction close to the limit plate 503 due to the obstruction of the hanging block 508. Then insert the bearing rod 504 into the interior of the pressure plate body 4, and at the same time make the surface of the block 501 contact the screw 2, and then rotate the hanging block 508. After a certain angle, the surface of the hanging block 508 is no longer in contact with the limit plate 503. At this time, the baffle 509 can slide in the direction close to the limit plate 503. After the baffle 509 slides a certain distance, the baffle 509 slides to the inner wall of the rectangular groove 507 on the load-bearing rod 504, and the inner wall of the clamping groove 512 on the baffle 509 is in contact with the clamping column 511. At this time, when using the pressure plate mechanism, the support structure 5 can replace the shim to support the pressure plate mechanism. By setting the support structure 5, the staff does not need to replace different shims when using the pressure plate mechanism to fix the workpiece, reducing the demand for different shims, thereby improving the overall work efficiency.

[0035] When using the support structure 5, slide the auxiliary block 62 downward. After the auxiliary block 62 slides a certain distance, stop sliding the auxiliary block 62. At this time, when using the support structure 5, the auxiliary block 62 can assist the support structure 5 in supporting. When the support structure 5 is not needed, slide the auxiliary block 62 upward. After the auxiliary block 62 slides a certain distance under the support of the lifting rod 61, the insert pad 63 on the block 501 is inserted into the inner wall of the rectangular hole 64. At this time, the insert pad 63 is stuck on the inner wall of the rectangular hole 64 by elastic force. At this time, the block 501 and the auxiliary block 62 are fixed, achieving the effect of fixing the block 501 and the auxiliary block 62. By setting the auxiliary structure 6, the contact area between the support structure 5 and the screw rod 2 can be increased, and the auxiliary support structure 5 is supported on the screw rod 2, thereby improving the stability of the support structure 5.
