Description

Technical Field

[0001] This utility model relates to the field of motor bracket clamping technology, specifically a clamping fixture for a generator bracket machining center. Background Technology

[0002] The motor bracket is a key load-bearing and positioning component of the motor assembly, requiring extremely high dimensional tolerances and hole precision. During mass production, specialized fixtures are needed to reliably secure it.

[0003] However, existing fixtures for generator bracket machining centers have the following problems during use: 1. Highly specialized and lacking flexibility: Most of them are "fixtures" designed for a single model of bracket. When the product is changed, the entire fixture needs to be replaced, resulting in high costs and long downtime.

[0004] 2. Unstable positioning accuracy: Traditional fixtures use multi-point independent positioning and pressure plates, resulting in large cumulative errors. Furthermore, they are prone to elastic deformation under clamping force, which affects the final processing and inspection accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture for a generator bracket machining center to solve the related problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a fixture for a generator bracket machining center, comprising a fixture plate, a hydraulic cylinder and a pneumatic cylinder. The fixture plate has a threaded hole at its top end. A guide plate for positioning is bolted to the top end of the fixture plate. A hydraulic cylinder for clamping the generator bracket is bolted to the top end of the fixture plate. A pneumatic cylinder is provided at the bottom end of the fixture plate, and a connecting seat is installed at the output end of the pneumatic cylinder. A support seat is sleeved on the top end of the connecting seat, and a positioning pin is installed on the top end of the support seat.

[0007] As a preferred embodiment of the fixture for a generator bracket machining center according to this utility model, the fixture plate is a base plate with matrix mounting holes.

[0012] The advantages of the clamp for a generator bracket machining center according to this utility model are as follows: 1. This utility model uses a hydraulic cylinder to push a double-fork pressure plate around a rocker arm block, causing a pressure sensor to press down on the motor bracket. The starting cylinder drives the support seat and positioning pin to insert into the position of the motor bracket. This structure can better fix the position of the motor bracket. Since the pressure sensor feeds back the pressing information to the microcontroller, the microcontroller can upload it to the controller, and the controller can control the pressure to avoid excessive pressure that could damage the motor bracket.
