Description

Technical Field

[0002] In the traditional motor bracket processing process, the fast and accurate positioning and clamping of the motor bracket is a very important part of the entire processing process, and it is also an important guarantee to ensure the processing accuracy and processing efficiency of the motor bracket. The traditional motor bracket processing and clamping is to place the motor bracket on the fixture by hoisting, then align it mechanically, and finally tighten it manually. This operation method is not only labor-intensive, but also low in efficiency, causing great inconvenience to production, which will result in relatively low overall processing efficiency. At the same time, there are certain safety hazards. Summary of the invention

At the same time, it can effectively improve the production efficiency of the motor bracket, and can also make the assembly and subsequent maintenance of the motor bracket more convenient.

[0004] The present invention provides a motor bracket processing fixture, comprising a supporting platform, a rear positioning mechanism, a pair of rotating clamping mechanisms, a pair of rotating tensioning mechanisms, a plurality of guide seats and a plurality of bottom positioning seats;

[0005] The rear positioning mechanism and a pair of rotating clamping mechanisms are relatively fixedly connected to the front and rear ends of the upper part of the support platform; the rear positioning mechanism is composed of a rear positioning seat located at the lower part and a rear positioning bracket fixedly connected to the upper part of the rear positioning seat, and the upper end of the rear positioning seat has a pair of support plates extending horizontally to the rear side at its left and right ends; a pair of rotating clamping mechanisms are vertically arranged and are respectively arranged at the left and right ends of the upper part of the valve body connecting plate, and the rotating clamping mechanism is an angle oil cylinder, and its clamping arm is arranged close to the upper side;

[0009] In this technical solution, multiple guide seats cooperate with the rear positioning mechanism to form a positioning space for accommodating the motor bracket to be processed, which can facilitate the rapid alignment of the motor bracket to the processing position after it is placed. Multiple bottom positioning seats facilitate effective support for the motor bracket to be processed. A pair of rotating tensioning mechanisms can facilitate the tightening of the upper part of the inserted motor bracket and the first clamping and fixing, and a pair of rotating clamping mechanisms can facilitate the clamping of the lower part of the tightened motor bracket and the second clamping and fixing. The secondary clamping and fixing can effectively clamp and position the motor bracket to be processed, thereby facilitating subsequent processing operations.

[0021] The rear positioning mechanism and a pair of rotary clamping mechanisms 2 are relatively fixedly connected to the front and rear ends of the upper part of the support platform; the rear positioning mechanism is composed of a rear positioning seat 6 located at the lower part and a rear positioning bracket 5 fixedly connected to the upper part of the rear positioning seat 6, and the upper end of the rear positioning seat 6 has a pair of support plates 13 extending horizontally to the rear side at its left and right ends; a pair of rotary clamping mechanisms 2 are vertically arranged, and are respectively arranged at the left and right ends of the upper part of the valve body connecting plate 7, and the rotary clamping mechanism 2 is an angle cylinder, and its clamping arm is arranged upward; when the two rotary clamping mechanisms 2 are in the fully extended state, their clamping arms are arranged toward the rear, and when the rotary clamping mechanism 2 is in the contraction process, its clamping arm gradually rotates inward, and after fully contracted, the clamping arm presses the motor bracket 12 to be processed to the tightest state.

[0022] A pair of rotating tensioning mechanisms 4 are horizontally fixedly connected to the upper part of a pair of support plates 13. The rotating tensioning mechanisms 4 are angle cylinders, and their clamping arms are arranged toward the rear side. When the two rotating tensioning mechanisms 4 are in a fully extended state, their clamping arms are arranged upward. When the rotating tensioning mechanisms 4 are in a contraction process, their clamping arms gradually rotate downward, and after being fully contracted, the clamping arms clamp the motor bracket 12 to be processed to the tightest state.

[0023] A plurality of guide seats 3 are fixedly connected to the four sides of the upper part of the support platform, and are located between the rear positioning mechanism and a pair of rotating clamping mechanisms 2, and cooperate with the rear positioning mechanism to form a positioning space for accommodating the motor bracket 12; the guide seat 3 is L-shaped, and has a vertical section located at the upper part and a horizontal section located at the bottom. The guide seat 3 is fixedly connected to the upper part of the support platform through the horizontal section, and the three guide seats 3 are distributed in a triangular shape, and the vertical sections of the three guide seats 3 are all arranged toward the center of the positioning space. As a preferred embodiment, one of the three guide seats 3 is arranged on the right side of the upper part of the support platform, and the other two are arranged on the left side of the upper part of the support platform, and are respectively arranged close to the rear positioning mechanism and the rotating clamping mechanism 2; as a preferred embodiment, a guide bevel is arranged on the upper part of the vertical section of the guide seat 3, and the upper end of the guide bevel is farther away from the positioning space than its lower end. By setting the guide bevel, the motor bracket 12 to be processed can be easily placed in the positioning space, and at the same time, it is also convenient to realize automatic alignment and positioning during the placement process.

[0024] A plurality of bottom positioning seats 10 are respectively arranged at the four corners of the positioning space and are fixedly connected to the supporting platform.

[0025] As a preferred embodiment, the support platform is composed of a support base 14 located at the bottom and a valve body connecting plate 7 fixedly connected to the upper part of the support base 14 .

[0026] like Figure 3As shown, in order to realize fully automated positioning and clamping operations, the outside of the valve body connecting plate 7 is respectively installed with a connecting valve 1, a first three-position four-way electromagnetic reversing valve 15, a second three-position four-way electromagnetic reversing valve 16, a one-way valve 8, a pressure gauge 9 and a sequence valve 11. As a preferred embodiment, the connecting valve 1, the first three-position four-way electromagnetic reversing valve 15, the second three-position four-way electromagnetic reversing valve 16, the one-way valve 8 and the pressure gauge 9 are all installed around the outer edge of the connecting plate 7, and the sequence valve 11 is installed on the upper part of the connecting plate 7, and the upper end of the sequence valve 11 is lower than the upper end of the bottom positioning seat 10; an oil inlet connecting pipeline 17 and an oil outlet connecting pipeline 18 are provided in the connecting valve 1. As a preferred embodiment, the oil inlet connecting pipeline 17 and the oil outlet connecting pipeline 18 are both provided with control valves for controlling their on and off. The oil outlet end of the oil inlet connecting pipeline 17 is connected to the oil inlet of the one-way valve 8 through the oil inlet channel A19 provided in the valve body connecting plate 7. The oil outlet of the one-way valve 8 is connected with the P port of the first three-position four-way electromagnetic reversing valve 15 through the oil inlet channel B20 arranged in the valve body connecting plate 7, and is also connected with the oil inlet port of the sequence valve 11 through the oil inlet channel C21 arranged in the valve body connecting plate 7. The oil outlet of the sequence valve 11 is connected with the P port of the second three-position four-way electromagnetic reversing valve 16 through the oil inlet channel D22 arranged in the valve body connecting plate 7. The T port of the first three-position four-way electromagnetic reversing valve 15 and the T port of the second three-position four-way electromagnetic reversing valve 16 are both connected with the oil inlet end of the oil outlet connecting pipeline 18 through the oil return channel 23 arranged in the valve body connecting plate 7; the A port and the B port of the first three-position four-way electromagnetic reversing valve 15 are respectively connected with the rod chamber and the rodless chamber of the rotary tensioning mechanism 4 through pipelines, and the A port and the B port of the second three-position four-way electromagnetic reversing valve 16 are respectively connected with the rod chamber and the rodless chamber of the rotary clamping mechanism 2 through pipelines.

In this way, as long as the left position of the first three-position four-way electromagnetic reversing valve 15 and the second three-position four-way electromagnetic reversing valve 16 are controlled to be energized and work in the left position when alignment and clamping are required, the setting of the sequence valve 11 can ensure that the high-pressure oil passes through the first three-position four-way electromagnetic reversing valve 15 and the second three-position four-way electromagnetic reversing valve 16 first and ... The three-position four-way electromagnetic reversing valve 15 is supplied to the rotary tensioning mechanism 4, so that the rotary tensioning mechanism 4 is preferably actuated to first pull the inserted motor bracket 12 to the position close to the rear positioning mechanism and realize effective tensioning and positioning. At the same time, after the rotary tensioning mechanism 4 tightens the motor bracket 12, the high-pressure oil is supplied to the rotary clamping mechanism 2 through the second three-position four-way electromagnetic reversing valve 16, so that the rotary clamping mechanism 2 is actuated after the rotary tensioning mechanism 4 is actuated to further clamp the tightened motor bracket 12, thereby realizing more effective clamping and positioning.When the first three-position four-way solenoid reversing valve 15 and the second three-position four-way solenoid reversing valve 16 are working in the left position, the oil circuit between the P port and the A port is connected, and the oil circuit between the T port and the B port is connected.

Multiple bottom positioning seats facilitate the effective support of the motor bracket to be processed. A pair of rotating tensioning mechanisms can facilitate the tightening of the upper part of the inserted motor bracket and the first clamping and fixing, and a pair of rotating clamping mechanisms can facilitate the clamping of the lower part of the tightened motor bracket and the second clamping and fixing. The secondary clamping and fixing can effectively clamp and position the motor bracket to be processed, thereby facilitating subsequent processing operations. The clamp can realize automatic alignment and clamping after clamping, which can effectively reduce the work intensity and save the turnover time of the motor bracket. At the same time, it can effectively improve the production efficiency of the motor bracket and make the assembly and subsequent maintenance of the motor bracket more convenient.
