Description

Technical Field

[0001] This utility model discloses a clamping and rotating fixture for end cap processing, which relates to the field of end cap processing fixture technology. Background Technology

[0002] Motor end caps are an important component of the motor structure, typically located at both ends of the motor. They enclose the motor's exterior, protect internal components, and provide structural support. Circular is the most common shape for motor end caps because motors are usually cylindrical, and circular end caps better fit the shape of the motor housing, providing uniform support and sealing. Four sets of evenly distributed screws are provided around the perimeter for mounting. When machining the screws on a drilling machine, the end caps need to be securely clamped.

[0003] Traditional end cap machining is performed on a fixture on a machining table. After machining, the workpiece needs to be disassembled and installed on another worktable. This disassembly and installation takes a lot of time for the operator. In addition, the method used to fix the end cap in the past was to tighten it with bolts. During machining, the high intensity of the operation may cause the fixed end cap to loosen, which will affect the machining quality. Therefore, there is a need to provide a clamping and rotating fixture for end cap machining to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and rotating fixture for end cap processing, so that the same end cap can be processed on the same workbench on the main side while providing a strengthening and stabilizing effect during processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping and rotating fixture for end cap processing, comprising a mounting base, characterized in that: a rotating seat is rotatably mounted on the mounting base, and a worktable is mounted on the rotating seat; the worktable includes a placement plate, a connecting seat is fixedly mounted at the center of the upper part of the placement plate, an abutment block is slidably mounted on the connecting seat, a telescopic shaft is slidably mounted at the axis of the placement plate, and a transmission block is mounted on the upper end of the telescopic shaft.

[0006] Preferably, the rotating seat is driven by a motor, and the telescopic shaft is controlled by a cylinder.

[0007] Preferably, four sets of contact blocks are provided, the shape of the contact blocks is a quarter circle arc, and the inner wall of the contact blocks is provided with an inner slope.

[0008] Preferably, the outer side of the transmission block is provided with an outer ramp, the angle of which is greater than that of the inner ramp inside the contact block.

[0009] Preferably, the outer side of the placement tray is provided with four sets of bayonets.

[0010] Preferably, the connecting seat is provided with several sets of guide rails, which are slidably connected to the abutment block. The function of the guide rails is to limit the movement direction of the abutment block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The operator aligns the center hole of the end cap part with the axis of the telescopic shaft, so that it is sleeved on the outside of the telescopic shaft. Then, the cylinder is started to drive the telescopic shaft to move downward, which drives the transmission block installed on it to move downward. The abutment block is squeezed and expands outward along the connecting seat until it abuts the inner ring of the end cap's inner hole, so that it is tightened and clamped. After the movement between the transmission block and the abutment block tightens and fixes the inner ring of the end cap part, the operator aligns the fixing plate with the center axis of the transmission block, and then screws the connecting screw into the transmission block until it is tightened. The bottom surface of the fixing plate is attached to the upper surface of the end cap part to fix its upper surface. In this way, the same end cap can be processed on the same workbench on the main side while strengthening and stabilizing it during processing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples:

[0018] like Figure 1 As shown, a clamping and rotating fixture for end cap processing includes a mounting base 1, a rotating seat 2 rotatably mounted on the mounting base 1, a worktable 3 mounted on the rotating seat 2, and the rotating seat 2 being driven by a motor.

[0019] The rotating seat 2 can rotate on the mounting seat 1. It is driven by a motor. The function of the rotating seat 2 is to switch the position of the worktable 3. When the front of the worktable 3 is facing up, the drill will drill the hole on the upper surface of the end cover. When the side is facing up, the side of the motor end cover will be processed.

[0020] like Figure 2 As shown, the workbench 3 includes a placement tray 31, a connecting seat 32 is fixedly installed at the center of the upper part of the placement tray 31, an abutment block 33 is slidably installed on the connecting seat 32, a telescopic shaft 34 is slidably installed at the axis of the placement tray 31, a transmission block 35 is installed at the upper end of the telescopic shaft 34, and the telescopic shaft 34 is controlled by a cylinder drive.

[0021] The specific working method of the workbench 3 is as follows: align the center hole of the end cap part with the axis of the telescopic shaft 34, so that it is sleeved on the outside of the telescopic shaft 34. Then start the cylinder to drive the telescopic shaft 34 to move downward, which in turn drives the transmission block 35 installed on it to move downward, squeezing the contact block 33 to expand outward along the connecting seat 32 until it contacts the inner ring of the end cap inner hole, so that it is tightened and clamped.

[0022] The abutment block 33 is provided in four sets, and the shape of the abutment block 33 is a quarter circle arc. The inner wall of the abutment block 33 is provided with an inner slope.

[0023] The four sets of contact blocks 33 can move simultaneously when the transmission block 35 presses down, which can better tighten the inner ring of the end cap part. The arc-shaped setting can fit the inner ring of the end cap part. The function of the inner slope is to make the transmission block 35 press down smoothly to push the four sets of contact blocks 33 outward, making the structure more stable.

[0024] The outer side of the transmission block 35 is provided with an outer ramp, the slope angle of which is greater than the inner ramp inside the contact block 33.

[0025] The outer ramp can fit into the inner ramp of the contact block 33, and its angle is greater than that of the inner ramp, which makes the extrusion motion of the transmission block 35 more powerful, thus making the structure more stable.

[0026] After the movement between the transmission block 35 and the abutment block 33 tightens and fixes the inner ring of the end cover, the end cover parts may still become loose, which may affect the accuracy of the drilling position. Therefore, an internal threaded hole (not shown in the figure) is provided at the central axis of the transmission block 35. A connecting screw 36 is engaged in the internal threaded hole, and a fixing plate 37 is installed below the connecting screw 36.

[0027] In practical application, after the movement between the transmission block 35 and the abutment block 33 tightens and fixes the inner ring of the end cap, the operator aligns the fixing plate 37 with the central axis of the transmission block 35, and then screws the connecting screw 36 into the transmission block 35 until it is tightened. The bottom surface of the fixing plate 37 is in contact with the upper surface of the end cap to fix its upper surface.

[0028] The outer side of the placement tray 31 is provided with four sets of bayonets 311;

[0029] After the end cap part is placed into the workbench 3, the operator can place it in the connecting block slots 311 at the four corners of the end cap to complete the initial positioning, so that the end cap part is not easy to move when it is pressed.

[0030] The connecting seat 32 is provided with several sets of guide rails 321, which are slidably connected to the abutment block 33. The function of the guide rails 321 is to limit the movement direction of the abutment block 33.

[0031] In summary, the operator aligns the center hole of the end cap part with the axis of the telescopic shaft 34, allowing it to fit onto the outside of the telescopic shaft 34. Then, the cylinder is activated, driving the telescopic shaft 34 downwards, which in turn moves the transmission block 35 mounted on it downwards. This causes the contact block 33 to expand outwards along the connecting seat 32 until it contacts the inner ring of the end cap's inner hole, tightening and clamping it. After the movement between the transmission block 35 and the contact block 33 tightens and fixes the inner ring of the end cap part, the operator aligns the fixing plate 37 with the center axis of the transmission block 35, and then screws the connecting screw 36 into the transmission block 35 until it is tightened. The bottom surface of the fixing plate 37 fits against the upper surface of the end cap part, fixing its upper surface. This allows the same end cap to be machined on the same workbench 3 while simultaneously providing reinforcement and stability during processing.

[0032] The above description is merely a preferred embodiment of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
