Description

Technical Field

[0001] This utility model relates to the field of motor processing fixture technology, specifically a motor housing fixing fixture to prevent misalignment. Background Technology

[0002] The motor housing is a major external component of the motor, including the recessed joint and the arm plate. It requires various machining processes to meet assembly requirements. During machining, it mainly relies on fixtures for fixing and clamping. Ordinary motor housing fixing fixtures generally use simple positioning pins for direct positioning. However, due to the symmetrical structure on both sides of the motor housing, if the operator places it in the wrong direction, it may still be placed into the fixture, causing problems such as misalignment of subsequent assembly stations, hole deviation, or reversed machining surfaces. In addition, some motor housings are directly clamped with metal clamping arms, which can easily cause indentations or deformation on the outer wall of the housing, which is not conducive to subsequent assembly accuracy control.

[0003] Based on this, this utility model designs a motor housing fixing fixture to prevent misalignment, in order to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a motor housing fixing fixture to prevent misalignment, so as to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor housing fixing fixture for preventing misalignment, comprising: a counterweight plate and a motor housing; a detachable shim block and two telescopic cylinders are installed on the top of the counterweight plate, and the two telescopic cylinders are symmetrically arranged on both sides of the shim block; The motor housing includes an inner concave joint integrally formed on its outer wall and two arm plates. The two arm plates are symmetrically arranged and each has a through hole on its outer wall. The top of the shim block is threaded with two symmetrical positioning pins. The two arm plates are inserted into each other through the through holes and the two positioning pins, so that the motor housing is placed on the top of the shim block. The top of the shim block is threaded with an anti-misalignment post, and one end of the anti-misalignment post is away from the concave joint and abuts against the inner wall of the motor housing. The telescopic end of the telescopic cylinder is hinged with a connector, and one end of the telescopic shaft of the telescopic cylinder is hinged with a clamping arm. One end of the connector is hinged to the outer wall of the clamping arm, and one end of the clamping arm is set towards the motor housing and is detachably connected with a buffer part, which extends to the top of the arm plate.

[0006] Preferably, one end of the clamping arm has a slot, and the buffer part includes a rubber clamp and a locking bolt. The rubber clamp is inserted into the slot of the clamping arm and locked by the locking bolt.

[0007] Preferably, the slot of the clamping arm has a threaded groove, the outer wall of the rubber chuck has an insertion hole, and the threaded end of the locking bolt passes through the insertion hole and is threaded into the threaded groove, so that the rubber chuck is locked to one end of the clamping arm.

[0008] Preferably, the counterweight plate has multiple through holes from the bottom, and the bottom of the shim block and the telescopic cylinder have threaded grooves corresponding to the through holes of the counterweight plate. The counterweight plate is locked and installed with the shim block and the telescopic cylinder respectively by bolts passing through the through holes and connecting to the threaded grooves.

[0009] Preferably, the anti-misalignment post and the positioning pin are detachable and interchangeable via a threaded connection to accommodate anti-misalignment positioning for motor housings of more specifications.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the detachable anti-misalignment post and the recessed joint of the motor housing form an anti-misalignment structure. When used with the positioning pin, if the clamping direction is incorrect, the motor housing cannot be lowered, thus forcing the consistency of direction and avoiding reverse installation errors during production. Secondly, one end of the clamping arm, together with the locking bolt, forms a buffer clamping structure, which can effectively prevent the shell from being deformed or scratched by the metal clamp. If the rubber clamp is worn, the locking bolt can be removed and a new clamp can be replaced, making maintenance simple. Attached Figure Description

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a motor housing fixing fixture for preventing misalignment, comprising: a counterweight plate 1 and a motor housing 2; a detachable shim block 3 and two telescopic cylinders 6 are installed on the top of the counterweight plate 1, and the two telescopic cylinders 6 are symmetrically arranged on both sides of the shim block 3; The motor housing 2 includes an inner concave joint 11 integrally formed on its outer wall and two arm plates 10. The two arm plates 10 are symmetrically arranged and each has a through hole on its outer wall. The top of the shim block 3 is threaded with two symmetrical positioning pins 5. The two arm plates 10 are inserted into the two positioning pins 5 through the through holes, so that the motor housing 2 is placed on the top of the shim block 3. The top of the shim block 3 is threaded with an anti-misalignment post 4, and one end of the anti-misalignment post 4 is away from the concave joint 11 and abuts against the inner wall of the motor housing 2. The telescopic end of the telescopic cylinder 6 is hinged with a connector 7, and one end of the telescopic shaft of the telescopic cylinder 6 is hinged with a clamping arm 8. One end of the connector 7 is hinged to the outer wall of the clamping arm 8, and one end of the clamping arm 8 is set towards the motor housing 2 and is detachably connected with a buffer part, which extends to the top of the arm plate 10. By detachably installing a shim block 3 and two telescopic cylinders 6 on the top of the counterweight plate 1, and setting anti-misalignment posts 4 and positioning pins 5, multi-point limiting and directional anti-misalignment positioning of the motor housing 2 can be achieved; the telescopic cylinders 6 drive the clamping arms 8 to clamp the motor housing 2, and the buffer part provides flexible pressure on the motor housing 2 to prevent clamping deviation and damage, so that the motor housing 2 can automatically distinguish the direction when it is placed, preventing the concave joint 11 from being directly aligned with the anti-misalignment post 4 and causing incorrect installation. At the same time, the clamping arms 8 and the buffer part clamp together to improve the fixing stability and protection performance, and the clamping operation is safe and efficient.

[0016] More preferably, one end of the clamping arm 8 is provided with a slot, and the buffer part includes a rubber clamp 9 and a locking bolt 12. The rubber clamp 9 is inserted into the slot of the clamping arm 8 and locked by the locking bolt 12. A slot is provided at the end of the clamping arm 8. The buffer part consists of a rubber chuck 9 and a locking bolt 12. The rubber chuck 9 is inserted into the slot of the clamping arm 8 and locked by the locking bolt 12, realizing a replaceable buffer clamping structure at the end of the clamping arm 8. The rubber chuck 9 has good elasticity and anti-slip properties, which can effectively buffer the pressure when the telescopic cylinder 6 clamps, and prevent the outer wall of the motor housing 2 from being deformed or scratched. At the same time, the locking bolt 12 structure is easy to replace and maintain, and improves the service life of the fixture.

[0017] More preferably, the slot of the clamping arm 8 is provided with a threaded groove, the outer wall of the rubber chuck 9 is provided with an insertion hole, and the threaded end of the locking bolt 12 passes through the insertion hole and is threadedly connected to the threaded groove, so that the rubber chuck 9 is locked to one end of the clamping arm 8. The slot of the clamping arm 8 has a threaded groove, and the outer wall of the rubber chuck 9 has an insertion hole. The threaded end of the locking bolt 12 passes through the insertion hole and is screwed into the threaded groove. The rubber chuck 9 is fixed to the end of the clamping arm 8 by the threaded locking method, realizing a stable and detachable connection structure. The threaded groove and the locking bolt 12 make the rubber chuck 9 securely installed and not easy to loosen, ensuring clamping stability. At the same time, the structure is simple and easy to install and disassemble. The chuck can be quickly replaced according to different motor housing 2 specifications, improving the applicability and flexibility of the fixture.

[0018] In a further preferred embodiment, the counterweight plate 1 has multiple through holes from the bottom, and the bottom of the shim block 3 and the telescopic cylinder 6 have threaded grooves corresponding to the through holes of the counterweight plate 1. The counterweight plate 1 is locked and installed with the shim block 3 and the telescopic cylinder 6 respectively by bolts passing through the through holes and connecting to the threaded grooves. The counterweight plate 1 has multiple through holes at its bottom. The bottom of the shim block 3 and the telescopic cylinder 6 are respectively provided with threaded grooves corresponding to the through holes. After the bolts are passed through the through holes and connected to the threaded grooves, they are locked, so that the counterweight plate 1, the shim block 3 and the telescopic cylinder 6 form a stable and detachable installation structure, which is convenient for installation, disassembly and maintenance. The shim block 3 or the telescopic cylinder 6 can be quickly replaced according to different working conditions. The installation is reliable and vibration-proof and stable. At the same time, the threaded connection enhances the overall rigidity of the counterweight plate 1 and the upper components, and extends the service life of the fixture.

[0019] Furthermore, the anti-misalignment post 4 and the positioning pin 5 are detachable and interchangeable via a threaded connection to accommodate the anti-misalignment positioning of motor housings 2 of more specifications. The error-proof column 4 and the positioning pin 5 are connected by threads, which can be disassembled and replaced. By adapting the installation length to the mounting hole positions of different models of motor housing 2 and the depth of the concave connector 11, multi-specification compatibility is achieved, which improves the versatility and adjustability of the error-proof positioning mechanism. It can adapt to different motor housing 2 structures without replacing the overall fixture, reducing production costs and maintenance difficulty, and enhancing the applicability of the fixture in batch assembly lines.

[0020] A specific application of this embodiment is as follows: The counterweight plate 1 is placed stably on the workbench. The shim block 3 and the telescopic cylinder 6 are locked and fixed to the counterweight plate 1 in sequence by bolts. Then, when fixing the motor housing 2, the motor housing 2 is lifted so that the through hole of the arm plate 10 is aligned with the positioning pin 5 of the shim block 3 and lowered. If the motor housing 2 is placed in the correct direction, the concave joint 11 and the anti-misalignment column 4 are in a misaligned relationship, and the motor housing 2 can be smoothly pressed down and positioned. If the orientation is incorrect, that is, the concave connector 11 is directly opposite the anti-misalignment post 4, the anti-misalignment post 4 will push against the concave connector 11 of the motor housing 2, causing the motor housing 2 to be unable to be inserted, thus achieving a physical anti-misalignment effect. After the motor housing 2 is correctly placed, the drive system of the telescopic cylinder 6 is started. The telescopic cylinder 6 drives one end of the clamping arm 8 to move upward. At the same time, the downward pull of the connector 7 causes the rubber clamp 9 at one end of the clamping arm 8 to contact the surface of the arm plate 10 of the motor housing 2. Since the rubber clamp 9 has a certain elasticity, it can effectively buffer the clamping force, prevent the outer wall from being hard squeezed, and ensure the clamping firmness.

[0021] Each telescopic cylinder 6 is hydraulically driven and centrally controlled by an external hydraulic control system. The control system includes a power module and a hydraulic control module, which can automatically or manually start and stop each telescopic cylinder 6 according to the process sequence.
