Abstract
Description
Technical Field
[0001] This utility model relates to a lateral riveting fixture, specifically a lateral riveting fixture for motor housings, belonging to the field of motor housing processing technology. Background Technology
[0002] The motor housing mainly consists of a lower shell and an upper cover, which are generally made of metal. They are usually joined together by riveting with a jig to form a whole. However, the riveting method used is to put the lower shell and the upper cover together, place them in the jig, and use equipment to press the jig down. The jig is designed with several cutting edges to press and bend the cut edges of the lower shell downward and inward to create several protrusions for fixation.
[0003] However, when the jig is pressed down for riveting, a large vertical impact force is applied directly to the top of the housing during the pressing process, which can easily cause the housing surface to dent and deform, affecting the appearance quality of the product. In severe cases, it can even affect the subsequent assembly process. Moreover, the existing jigs mainly rely on simple mechanical clamping to fix the housing, which is not only cumbersome and inefficient, but also prone to displacement of the housing due to insecure fixing during the riveting process, affecting the riveting accuracy. Utility Model Content
[0004] The purpose of this utility model is to provide a side riveting fixture for motor housing in order to solve the above problems. It can quickly clamp and fix the motor housing and perform side riveting on the motor housing. It can prevent the impact force from causing contact damage to the top of the motor housing when riveting the top of the motor housing, thereby affecting the subsequent processing of the motor housing.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a lateral riveting fixture for a motor housing, comprising a lower mold and an upper mold, wherein a riveting structure is installed on the lower mold and the upper mold, the riveting structure comprising a fixed seat, the top of the lower mold being fixedly connected to the fixed seat, and both sides of the fixed seat being slidably connected to abutment rods, both sides of the abutment rods being rotatably connected to abutment wheels, the bottom of the upper mold being fixedly connected to abutment seat, a limit ring being slidably connected inside the abutment seat, and a plurality of first springs being fixedly connected between the abutment seat and the limit ring, the bottom of the abutment seat having an inclined groove inside, and a riveting block being slidably connected to the bottom of the limit ring.

A slanted groove 307 is provided inside the bottom end of the abutment seat 304. A riveting block 308 is slidably connected to the bottom end of the limit ring 305.
[0022] As a technical optimization of this utility model, the inclined groove 307 has an inclined structure and the side end of the riveting block 308 has an arc-shaped structure, thereby enabling the riveting block 308 to slide.
[0023] As a technical optimization of this utility model, a fixing structure 4 is installed inside the abutment seat 304. The fixing structure 4 includes a connecting plate 401. The top end of the limiting ring 305 is fixedly connected to the connecting plate 401. The bottom end of the connecting plate 401 is slidably connected to the abutment ring 403. The top end of the abutment ring 403 is fixedly connected to the guide rod 402. The guide rod 402 and the connecting plate 401 are slidably connected. The other end of the guide rod 402 is fixedly connected to the fixing ring 404. A second spring 405 is fixedly connected between the fixing ring 404 and the abutment seat 304, thereby enabling the positioning of the motor housing during the riveting process.
[0024] As a technical optimization of this utility model, a limiting structure 5 is installed on the limiting ring 305. The limiting structure 5 includes a slider 501. The slider 501 is fixedly connected to the limiting ring 305. The slider 501 and the riveting block 308 are slidably connected. A third spring 502 is fixedly connected between the slider 501 and the riveting block 308, so as to drive the riveting block 308 to slide and reset.
[0025] As a technical optimization of this utility model, a limiting rod 503 is fixedly connected inside the riveting block 308, and the limiting rod 503 and the slider 501 are slidably connected, thereby guiding and limiting the slider 501.
[0026] As a technical optimization of this utility model, a transmission structure 6 is installed on the fixed base 301. The transmission structure 6 includes a slide rod 601. The slide rod 601 is slidably connected to both the left and right sides of the fixed base 301. The slide rod 601 and the abutment rod 302 are fixedly connected. The other end of the slide rod 601 has an arc-shaped structure. A fifth spring 605 is fixedly connected between the fixed base 301 and the abutment rod 302. An abutment plate 602 is slidably connected to the lower mold 1. A top rod 603 is fixedly connected to the abutment plate 602. The bottom end of the top rod 603 has an arc-shaped structure. The bottom end of the top rod 603 abuts against the slide rod 601. A fourth spring 604 is fixedly connected between the abutment plate 602 and the lower mold 1. A fixing rod 606 is fixedly connected to the bottom end of the upper mold 2. The fixing rod 606 abuts against the abutment plate 602, thereby automatically fixing the motor housing when the upper mold 2 slides downward.
[0027] In use, when riveting and fixing the motor housing, the lower mold 1 is installed on the worktable, and the upper mold 2 is installed on the lifting device. Then, the motor housing is placed inside the fixed base 301. After placement, the lifting device is activated to move the upper mold 2 downward. When the fixing rod 606 and the abutment plate 602 abut, the abutment plate 602 can drive the push rod 603 to slide downward. When the push rod 603 and the slide rod 601 abut, the slide rods 601 on the left and right sides of the fixed base 301 can slide towards each other simultaneously. Therefore, the two abutment rods 302 can slide inward. When the multiple abutment wheels 303 abut against the bottom of the motor housing, the motor housing can be quickly clamped and fixed. The upper mold 2 continues to slide downward. When the abutment ring 403 abuts against the top of the motor housing, the upper mold 2 continues to move, which can drive the guide rod 40 2. Sliding within the connecting plate 401, the upper mold 2 can drive the fixing ring 404 to slide. The elastic force of the second spring 405 can not only position the top of the motor housing, but also prevent direct fixing from damaging the motor housing. When the abutting ring 403 slides to abut against the connecting plate 401, the upper mold 2 continues to descend, which can drive the limiting ring 305 to slide within the abutting seat 304. Through the contact between the inclined groove 307 and the side end of the riveting block 308, multiple riveting blocks 308 can be driven to slide inward simultaneously. Therefore, the motor housing can be riveted laterally, preventing the impact force from causing abutment damage to the top of the motor housing when riveting it at the top, thus affecting the subsequent processing of the motor housing. The slider 501 and the third spring 502 can drive the riveting block 308 to slide and reset. The fixing rod 606 can guide and limit the riveting block 308.
