Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a shock-absorbing protection structure for processing a reducer fixing plate. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine.

[0003] According to patent application number: 202123426305.3, a shock-absorbing protection structure for processing a reducer fixing plate lifts the second clamping plate by pulling a hand lever, and places the plate between the first clamping plate and the second clamping plate, and then releases the hand lever so that the second clamping plate is pressed toward the plate under the pull of a compression spring to fix the plate. However, since two sets of first clamping plates and second clamping plates for fixing the plate are arranged on the workbench, before placing the plate, the staff needs to pull the two second clamping plates upward at the same time with both hands, and keep the plate in an upward state at all times during the placement of the plate. Therefore, two staff members are usually required to cooperate to complete the placement of the plate, so as to facilitate the operation and use of the staff.

[0004] In view of the above-mentioned defects, a shock-absorbing protection structure for processing a reducer fixing plate is provided. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problem and to propose a shock-absorbing protection structure for processing a reducer fixing plate.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a shock-absorbing protection structure for processing a reducer fixed plate, comprising a workbench, a support frame installed on the workbench, and a processing mechanism installed on the support frame, wherein two first clamping plates are fixedly arranged at the upper end of the workbench, a second clamping plate is vertically slidably arranged above the first clamping plate, and a fixing rod slidingly penetrating the second clamping plate is fixedly arranged at the upper end of the first clamping plate;

[0007] A tripod is fixed on the second clamping plate, and a transverse axis is rotatably connected inside the workbench. A transmission arm is coaxially fixed on the transverse axis, and the free end of the transmission arm is rotatably connected to the tripod. The outer sliding sleeve of the transverse axis is provided with a sliding sleeve that can drive the transverse axis to rotate. A driving member for controlling the horizontal sliding of the sliding sleeve is provided on the outer side of the workbench. A guide member is provided on the outer side of the workbench. When the sliding sleeve slides horizontally, the guide member drives the transverse axis to rotate. A stop member for limiting the sliding reset of the sliding sleeve is provided on the outer side of the workbench.

[0008] Preferably, the driving member comprises two rotary arms rotatably connected to the side ends of the sliding sleeve, and a handle is fixedly provided between the two rotary arms.

[0009] Preferably, the driving member also includes a side frame fixedly mounted on the side end of the sliding sleeve, a support rod slidingly passing through the side frame is fixedly mounted on the outer end of the workbench, a baffle is fixedly mounted on the end of the support rod away from the workbench, and a compression spring is sleeved on the outer side of the support rod to press the side frame inward.

[0010] Preferably, the guide member comprises a protrusion formed on the inner wall of the sliding sleeve, and a sliding rail for slidingly cooperating with the protrusion is formed on the side wall of the transverse axis.

[0011] Preferably, the blocking member comprises a rod fixedly arranged between two rotary arms, a stopper is fixedly arranged at the outer end of the workbench, and a notch groove for engaging with the rod is formed at one end of the stopper away from the workbench.

[0012] Preferably, a stop frame for limiting the rotation range of the swing arm is fixedly provided on the side end of the sliding sleeve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] In the present application, the sliding sleeve is pulled outward to control the two transmission arms fixed to the horizontal axis to rotate simultaneously, thereby driving the two second clamping plates to move up simultaneously. As the sliding sleeve frame rod slides outward away from the block, the swing arm is rotated by the handle to make the swing arm rotate to a vertical state. Subsequently, the frame rod is embedded in the recessed groove as the sliding sleeve slides to limit the sliding sleeve from continuing to slide inward. At this time, the staff no longer needs to manually maintain the lifted state of the second clamping plate, thereby achieving the purpose of facilitating the staff to place the plate.

Then, the limit on the sleeve 10 is released, and the sleeve 10 slides inwardly along the horizontal axis 9 to fix the plate. The transmission arm 8 is composed of two arms of equal length that are rotatably connected.

[0024] Specifically, Figure 1-4As shown, the driving member includes two swing arms 17 rotatably connected to the side ends of the sleeve 10, and a handle 19 is fixed between the two swing arms 17; the swing arms 17 are pulled outward by the handle 19, so that the sleeve 10 rotatably connected to the swing arms 17 slides outward along the horizontal axis 9.
