Description

Technical Field

[0001] The utility model relates to the technical field of motor accessory production, in particular to a bending jig for machining motor accessories. Background Technique

[0002] Motor accessories refer to the parts assembled in the motor by motor manufacturers as original motor accessories. The parts replaced due to improper use or wear are called motor accessories. Generally, the service life of accessories is not as long as that of the original parts. The devices used in the production and processing of motor accessories are particularly important in the field of motor accessory production. In particular, a bending jig for motor accessory production and processing is more conducive to improving production efficiency.

[0003] When the existing motor accessory bending equipment presses and bends accessories, during the pressing and bending process, the accessories need to shift as the mold moves. This causes the pressing and bending equipment to be unable to clamp the accessories. When the two sides of the accessories cannot move simultaneously and deviation occurs in the offset position, it will lead to inaccurate bending positions of the metal parts, and further cause the scrapping of the processed metal parts. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bending jig for machining motor accessories. By adopting this structure for work, it solves the problem that when the existing motor accessory bending equipment bends accessories, the clamping device of the accessories cannot move as the mold moves, resulting in the bending equipment being unable to clamp the accessories. When the two sides of the accessories cannot move simultaneously and deviation occurs in the offset position, it will lead to inaccurate bending positions of the metal parts, and further cause the scrapping of the processed metal parts.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A bending jig for machining motor accessories, including a base. Above the base is provided a bending head. Below the bending head is provided a clamping assembly. Inside the base is provided a movable groove. Inside the movable groove is provided a synchronization assembly. Above the synchronization assembly is provided a clamping assembly. The motor accessories are fixed by the clamping assembly. During bending, the clamping assembly moves synchronously through the synchronization assembly to avoid deviation in the bending position of the motor accessories.

[0006] Preferably, a group of columns are symmetrically arranged above the base. Above the columns is provided a top plate. Inside the top plate is provided a hydraulic cylinder. Below the hydraulic cylinder is connected a hydraulic telescopic rod. Below the hydraulic telescopic rod is provided a bending head. Below the inside of the movable groove is provided a first slide rail. The bending head is pushed by the hydraulic cylinder to bend the motor accessories.

[0007] Preferably, a placement table is provided on the upper surface of the base. A bending groove is formed in the middle above the placement table. A set of sliding grooves are formed through the positions of the placement table on both sides of the bending groove. The sliding grooves communicate with the inside of the movable groove. A second slide rail is provided inside the sliding groove. A connecting rod is slidably sleeved outside the second slide rail, so that the clamping assembly on the connecting rod moves along the second slide rail under force.

[0008] Preferably, the clamping assembly includes a clamping plate installed on the upper side of the connecting rod. A placement groove is provided below one side of the clamping plate close to the bending groove. A positioning telescopic rod is provided above the inside of the placement groove. A pressing plate is provided at the lower end of the positioning telescopic rod. The motor fitting is fixed by the pressing plate.

[0009] Preferably, an anti-slip pad is provided below the pressing plate. The interval between the anti-slip pad and the placement table is less than the thickness of the motor fitting. A spring is sleeved outside the positioning telescopic rod. The upper end of the spring is fixedly connected inside the placement groove, and the lower end of the spring is fixedly connected inside the pressing plate. The anti-slip pad increases friction, so that the motor fitting and the clamping assembly are stably fixed.

[0010] Preferably, the lower end of the connecting rod extends into the inside of the movable groove and is slidably connected to the outside of the first slide rail. A first push rod is provided on one side of a connecting rod, and a second push rod is provided on one side of the other connecting rod. The first push rod is located below the second push rod.

[0011] Preferably, a gear groove is provided above the movable plate connected to the first push rod, and a gear groove is provided below the movable plate connected to the second push rod. A gear is provided between the gear grooves. The gear meshes with the gear grooves on both sides. A rotating shaft is provided inside the gear. The two ends of the rotating shaft are arranged inside the base. The gear grooves on both sides are driven by the gear, so that the clamping assembly moves synchronously, and the motor fitting is stably fixed to prevent the bending position from shifting.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] A bending fixture for machining motor fittings proposed by the present utility model places the motor fittings on a placement table, positions the area to be bent above the bending groove, places the motor fittings under the pressing plate by lifting the pressing plate, and lowers the pressing plate to fix the motor fittings using the pressure of the spring. The hydraulic cylinder is started to control the hydraulic telescopic rod to push the bending head to stamp the motor fittings. At this time, the two sides of the motor fittings start to move towards the bending head as the bending head stamps, and the clamping assembly moves with the motor fittings under the tension, causing the connecting rod to drive the movable plate on the first push rod to move inwards. When the gear groove on the movable plate moves, it drives the gear to rotate, and the gear drives the gear groove on the movable plate connected to the second push rod, causing the movable plate to pull the clamping assembly on the second push rod to move towards the bending head, realizing the synchronous movement of the clamping assembly with the mold and avoiding the deviation of the bending position.
