[0002] The background technology of hardware processing positioning fixtures mainly involves the fields of mechanical manufacturing and precision machining. It is an important tool to ensure the accurate and stable position of hardware parts during the processing. The precision requirements of mechanical equipment and products are constantly improving, and the consistency of hardware dimensions and accuracy of geometric shapes make it crucial to design and use high-precision positioning fixtures.

[0003] In the process of clamping the workpiece, the workpiece needs to be clamped in the middle to avoid processing deviation during subsequent processing. In the previous positioning fixtures, the structure is often simple, and the effect of center positioning of the workpiece is not good, and deviation will occur.

[0004] Therefore, in the process of positioning the workpiece, in order to avoid the workpiece from being offset when being clamped and affecting subsequent processing, a positioning fixture for hardware processing is urgently needed to solve the existing problem. Utility Model Content

[0005] In view of this, the utility model aims to provide a positioning fixture for hardware processing to address the deficiencies in the prior art, which can prevent the workpiece from being offset when it is clamped during positioning, thereby ensuring the accuracy of subsequent processing positioning.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a positioning fixture for hardware processing, including a horizontal plate, a sliding support plate is fixedly installed on the horizontal plate, a vertical plate is fixedly installed on the top of one end of the horizontal plate, and a sliding bracket is installed on the top of the vertical plate, that is, the sliding bracket clamps the workpiece, a first motor is arranged on the rear side wall of the vertical plate, a transmission assembly is fixedly installed on the output shaft of the first motor, a first group of screw rods are arranged at both ends of the transmission assembly, and two are arranged and symmetrically installed, that is, the first group of screw rods drives the two sliding brackets to move symmetrically inward or outward at the same time under the action of the same transmission assembly, and a driving assembly is also fixedly installed on the horizontal plate, that is, the driving assembly acts on the sliding support plate.

[0007] The transmission assembly includes a second motor and a second screw rod. A wire drum is penetrated through the second screw rod, that is, the second motor drives the second screw rod to rotate, and then the wire drum moves.

[0008] The driving assembly comprises a driving roller group, and a transmission belt is connected to the driving roller group, that is, the driving roller group drives the first group of screw rods to rotate synchronously under the connection of the transmission belt and the action of the first motor.

[0009] The sliding support plate and the sliding bracket are both provided with a sliding groove and a sliding block, and the sliding block moves inside the sliding groove.

[0010] A bearing base is installed at the end of the first group of screw rods, that is, the bearing base can support the screw rods while rotating and prevent the sliding bracket from sliding off the screw rods.

[0011] A layer of friction pad is installed on both the sliding support plate and the sliding bracket. The material of the friction pad is rubber, that is, the friction pad increases the friction force when contacting with the workpiece.

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

[0013] The first set of screw rods drives the two sliding brackets to move symmetrically inward or outward at the same time under the action of the same transmission assembly, ensuring that the workpiece is in the center during the clamping process to avoid deviation and facilitate subsequent processing; the friction pad increases the friction when in contact with the workpiece, and in the process of the workpiece moving forward, the workpiece can be kept standing on the sliding support plate, not easy to fall, and the sliding bracket can clamp the workpiece more firmly.
