Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a processing clamp for a screw rod support seat. Background Art

[0002] A fixture is a tool used to hold a workpiece in place during machining on a CNC machine tool. It generally consists of a base plate, clamping elements, and locking elements. The base plate is usually fixed to the work surface and the clamping elements are connected to the base plate by screws or bolts. The locking elements are then used to hold the workpiece in place while it is being machined. The clamping elements can be adjusted to hold the workpiece securely in place or they can be loosened to facilitate repositioning or removal of the workpiece.

[0003] The utility model patent application document with the publication number "CN214024693U" discloses a processing fixture for a screw support seat, including a fixture body, a profiling fixed workpiece, a spindle hole, a chuck locking hole, a profiling fixed groove, a positioning hole, a positioning pin, a mounting groove, a workpiece locking hole and a locking bolt. This technical solution is directly connected to the spindle of a CNC lathe, and there is no need to install a rotary cylinder and a hydraulic station, thereby reducing equipment costs; the profiling fixed workpiece is provided with a profiling fixed groove that matches the product, thereby reducing clamping errors and unstable clamping phenomena; the profiling fixed workpiece is provided with a positioning pin inserted into the positioning hole to achieve high concentricity, which is convenient for quick clamping and locking, and is not easy to clamp the workpiece.

[0004] The processing fixture for the screw support seat disclosed in the above document has the following defects: the technical solution needs to install multiple positioning pins during the clamping process, which makes the clamping troublesome and reduces the work efficiency.

[0005] It can be seen from this that the existing processing fixture for the screw support seat does not have a good clamping structure, and it is necessary to improve the existing deficiencies and provide a processing fixture for the screw support seat. Utility Model Content

[0006] The purpose of the utility model is to provide a processing fixture for a screw support seat to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The utility model discloses a processing fixture for a screw rod support seat, comprising a base, a mounting shell is fixedly installed on the upper surface of the base, a through groove is provided on the inner bottom of the mounting shell, the through groove extends to the lower surface of the base, a driving structure is arranged inside the through groove, the driving structure comprises a bearing, a threaded tube, a gear, a screw rod, a stop plate, a movable block and a slot, the inner wall of the through groove is rotatably connected with the bearing, the inner wall of the bearing is fixedly installed with a threaded tube, the peripheral side surface of the threaded tube is fixedly installed with a gear, the internal thread of the threaded tube is connected with the screw rod, one end of the screw rod is fixedly installed with the stop plate, the lower surface of the stop plate is rotatably connected with the movable block, the peripheral side surface of the movable block is provided with a slot, the number of the slots is fixed to four, the lower surface of the movable block is fixedly installed with a spring, and the spring is connected to the inner bottom of the mounting shell.

[0009] Furthermore, a clamping shell is fixedly mounted on the upper surface of the mounting shell, and grooves are provided on the upper surface of the clamping shell, and the number of the grooves is fixed to four.

[0010] Furthermore, a rotating rod is fixedly installed inside the groove.

[0011] Furthermore, a clamping block is rotatably connected to the peripheral side surface of the rotating rod.

[0012] Furthermore, a connecting block is fixedly mounted on one side of the clamping block, the connecting block is clamped with the clamping slot, and an arc-shaped protrusion is fixedly mounted on one end of the clamping block.

[0013] Furthermore, the inner thread of the base is connected with a plurality of locking bolts.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model drives the gear to rotate through an external driving component to drive the threaded tube to rotate. Due to the setting of the bearing, the threaded tube can only rotate in place. The rotation of the threaded tube causes the screw rod to move downward, driving the movable block to move downward. The movable block moves downward so that the four clamping blocks are retracted toward the inside of the clamping shell, thereby clamping the mold. When disassembling the mold, the external driving component drives the gear in the opposite direction to push the screw rod upward, so that the clamping blocks expand outward to disassemble the mold. Disassembly is convenient and installation is quick, and the steps are simple to improve work efficiency.

[0016] (2) The utility model uses a spring to close the spring rebound of the external drive assembly after the mold is disassembled, thereby achieving the reset effect of the movable block and increasing the practicality.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
