Description

Technical Field

[0001] This utility model relates to the field of automotive starter motor drive cover processing technology, and in particular to a processing fixture for a lightweight automotive starter motor drive cover. Background Technology

[0002] As an important component of automobiles, the starter motor's drive cover is a cylindrical shape with one end sealed. Its bottom end has multiple grille ventilation holes, and its circumference has multiple positioning holes. After the starter motor drive cover blank is machined, it needs to be clamped and fixed using a fixture before the end face is machined to create the bearing positions and stops.

[0003] In the prior art, Chinese Patent Publication No. CN209717079U discloses a machining fixture for an automotive starter motor drive cover, belonging to the technical field of machining equipment for automotive starter motor drive covers. This machining fixture consists of an assembly plate, locating pins, a pull rod, pressure claws, support pins, and a support block. The assembly plate is a circular disc with a "convex" shaped cross-section. Multiple locating pins are evenly distributed on the stepped surface of the assembly plate. An assembly countersunk hole is provided inside the assembly plate. Multiple sets of pressure claws are evenly and movably mounted in the assembly countersunk hole via the support block and pivot pin A. A pull rod is slidably mounted on the assembly plate inside the support block. One end of the pull rod is movably connected to the corresponding pressure claw via pivot pin B. The other end of the pull rod extends to the outer end of the assembly plate and is threadedly connected to an adjusting nut. A locking spring is fitted on the pull rod on one side of the adjusting nut. This machining fixture has a compact structure and ingenious design; it solves the problem of workpiece extrusion and deformation that often occurs when clamping it using existing methods.

[0004] However, in actual use, this utility model is not convenient for buffering the drive cover when clamping it. When the pressure claw contacts and fixes the drive cover, the drive cover will be subjected to pressure at the moment of contact. The contact point range is small, resulting in greater local pressure. The clamping point of the drive cover is prone to denting. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a machining fixture for a lightweight drive cover of an automotive starter motor, which has a large clamping range, thereby preventing the drive cover from deforming or denting.

After the fixing plate is clipped onto the outer surface of the clamping plate, it is fixed with bolts. Both ends of the top of the fixing plate are fixed to prevent the fixing plate from falling off. When processing the drive cover, the drive cover is placed between the two clamping plates. The clamping plates have an arc shape, which fixes the arc of the fixing plate and ensures a close fit. After the cylinder is started, the telescopic rod is extended, thereby moving the clamping plate. The rubber strip is squeezed after contacting the outer surface of the drive cover. The rubber strip can play an anti-slip role and improve the clamping firmness. The rubber plate is pressed against the drive cover and buffers the clamping pressure. It has strong wrapping properties and a large clamping range, thereby preventing the drive cover from deforming and denting.

[0015] By adopting the above technical solution, the resistance block is inserted into the meshing groove, thereby making the positioning sleeve more stable. At the same time, the limiting ring increases the contact range and does not affect the rotation of the positioning sleeve.

[0016] A further feature of this invention is that a support ring is fixedly connected to the top of the base, and an annular groove is provided at the bottom of the adjusting seat.

[0017] By adopting the above technical solution, the support ring can rotate on the inner wall of the annular groove, supporting the edge.

[0018] A further feature of this invention is that a fixing block is fixedly connected to the outer surface of the base, and a fixing bolt is threadedly connected to the inside of the fixing block.

[0019] By adopting the above technical solution, the fixing block is fixed at the corresponding installation position using fixing bolts.

[0020] A further feature of this invention is that the number of meshing grooves is eight, and the eight meshing grooves are arranged in a circular array.

[0021] By adopting the above technical solution, the meshing grooves are evenly distributed, and the meshing connection is stable.

[0022] A further feature of this invention is that an anti-slip pad is fixedly connected to the bottom of the inner wall of the adjusting seat, and anti-slip particles are provided on the top of the anti-slip pad.

[0023] By adopting the above technical solution, the anti-slip pad contacts the bottom of the cover, increasing the anti-slip effect on the cover.

[0024] A further feature of this invention is that a corresponding ring is fixedly connected to the inner wall of the adjusting seat, and the telescopic rod passes through the interior of the corresponding ring.

[0025] By adopting the above technical solution, the telescopic rod can extend and retract inside the corresponding ring, and the outer surface of the telescopic rod does not contact the inner wall of the corresponding ring.

When the operator positions the adjusting seat and base vertically, the fixing buckle plate is secured to the outer surface of the clamping plate with bolts. Both ends of the fixing buckle plate are fixed to prevent it from falling off. When processing the cover, the cover is placed between the two clamping plates. The clamping plates have an arc shape, which helps to fix the curvature of the buckle plate and ensure a close fit. After the cylinder is activated, it drives the telescopic rod to extend, thereby moving the clamping plate. The rubber strip is compressed upon contact with the outer surface of the cover, providing anti-slip properties and improving the clamping firmness. The rubber plate, in contact with the cover, is compressed and buffers the clamping pressure, providing strong wrapping and a large clamping range, thus preventing deformation and denting of the cover.

During installation, the meshing groove and resistance block are aligned vertically, and the resistance block is inserted into the meshing groove, thereby making the positioning sleeve more stable. At the same time, the limiting ring increases the contact range without affecting the rotation of the positioning sleeve. The support ring can rotate on the inner wall of the annular groove. At the edge of the support, the fixing block corresponds to the required installation position and is fixed by fixing bolts. The meshing groove is evenly distributed, and the meshing is stable. The anti-slip pad contacts the bottom of the drive cover, increasing the anti-slip effect on the drive cover. The telescopic rod can extend and retract inside the corresponding ring, and the outer surface of the telescopic rod does not contact the inner wall of the corresponding ring.
