Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machining technology and relates to a positioning fixture. Background Technology
[0002] Existing fixtures typically have slots that match the production port, allowing the product to be positioned inside the slot and clamped by a pressure plate. However, this results in product wobbling and misalignment, inaccurate positioning, and the fact that each operation can only position products of the same specification, which is not conducive to the widespread use of the mold.
[0003] Therefore, how to provide a positioning fixture that can adapt to products of multiple sizes has become an urgent technical problem to be solved. Utility Model Content
[0004] To overcome the problems existing in the related technologies, this application aims to provide a positioning fixture that can adapt to products of multiple sizes.
[0005] This application is achieved through the following technical solution.
[0006] This technical solution provides a positioning fixture, including:
[0007] A fixture support, wherein at least one slot is provided on the top of the fixture support for positioning the product;
[0008] A movable component slidably connected inside the fixture support, the movable component including a traction block and a clamping rod, the traction block abutting against the outside of the fixture support and connected to the clamping rod;
[0009] The top of the clamping rod has a groove corresponding to the slot.
[0010] The present invention is further configured such that guide rods are provided at both ends of the traction block, and the guide rods are slidably connected to the inside of the fixture bracket.
[0011] The present invention is further configured such that the fixture bracket has two sets of limiting rods inside, with at least two in each set, and the two limiting rods are symmetrical about the movable component. The clamping rod has a limiting groove corresponding to the limiting rod on its outside, and the limiting rod is slidably connected to the inside of the limiting groove.
[0012] The present invention is further configured to include a pressure plate, which abuts against the top of the fixture bracket, the length of the groove is greater than or equal to the width of the product, the length of the groove body is greater than or equal to the length of the groove, the bottom wall of the groove body and the bottom wall of the groove are on the same plane, and the height of the groove body is lower than the height of the groove.
[0013] The present invention is further configured such that a fixing screw is installed inside the traction block, and the clamping rod is connected to the traction block through the fixing screw.
[0014] The present invention is further configured such that the traction block and the clamping rod are integrally formed.
[0015] The present invention is further configured such that the clamping rod is engaged inside the traction block.
[0016] The present invention is further configured such that a fixing block is installed at the tail of the fixture support to limit the depth of insertion of the movable component into the fixture support.
[0017] This utility model has the following beneficial effects: the movable component connected inside the fixture bracket, in conjunction with the fixture bracket, positions the product to cooperate with the milling cutter to complete the product processing. That is, as the traction block moves away from the product, it can squeeze and drive the product to move through the top groove of the clamping rod, and finally abut against the side wall of the groove to complete the clamping positioning of the product. Then, the positioning of the product is completed with the help of the pressure plate, which can be adapted to the alignment positioning of products of different specifications.
[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0024] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0026] This utility model embodiment discloses a positioning fixture, such as Figures 1-3 As shown, it includes:
[0027] The fixture support 1 has at least one slot 4 on its top for positioning the product.
[0028] The movable component 2 is slidably connected inside the fixture support 1. The movable component 2 includes a traction block 8 and a clamping rod 10. The traction block 8 abuts against the outside of the fixture support 1 and is connected to the clamping rod 10.
[0029] The top of the clamping rod 10 is provided with a groove corresponding to the slot 4.
[0030] It should be noted that the slots 4 are evenly spaced, and the slots are evenly distributed on the top of the clamping rod 10. The slots are located outside the slots 4 so that when the movable component 2 moves, the product is driven to abut against the inner wall of the slots 4 by the movement of the slots, thus forming a clamp.
[0031] like Figure 1 and Figure 3 As shown, guide rods 5 are provided at both ends of the traction block 8. The guide rods 5 are slidably connected to the inside of the fixture bracket 1. The guide rods 5 can assist in calibrating the movement path of the movable component 2.
[0032] like Figure 3 As shown, the fixture bracket 1 has two sets of limiting rods 6 inside, with at least two in each set, and the two limiting rods 6 are symmetrical about the movable component 2. The clamping rod 10 has a limiting groove 7 on the outside corresponding to the limiting rod 6, and the limiting rod 6 is slidably connected to the inside of the limiting groove 7.
[0033] It should be noted that the length of the limiting groove 7 is greater than the width of the limiting rod 6, which limits the movable distance of the movable component 2. At the same time, the position of the clamping rod 10 can be stabilized by the symmetrically arranged limiting rods 6 that abut against the inside of the limiting groove 7.
[0034] like Figure 2As shown, it also includes a pressure plate 3, which abuts against the top of the fixture bracket 1. The length of the slot 4 is greater than or equal to the width of the product, the length of the slot body is greater than or equal to the length of the slot 4, the bottom wall of the slot body is on the same plane as the bottom wall of the slot 4, and the height of the slot body is lower than the height of the slot 4.
[0035] like Figure 1 and Figure 2 As shown, a fixing screw is installed inside the traction block 8, and the clamping rod 10 is connected to the traction block 8 through the fixing screw.
[0036] like Figure 1 and Figure 2 As shown, the traction block 8 and the clamping rod 10 are integrally formed.
[0037] like Figure 1 and Figure 2 As shown, the clamping rod 10 is engaged inside the traction block 8.
[0038] like Figure 1 and Figure 2 As shown, a fixing block 11 is installed at the tail of the fixture bracket 1 to limit the depth of the movable component 2 inserted into the fixture bracket 1.
[0039] Working principle: The movable component 2, which is movably connected inside the fixture support 1, works with the fixture support 1 to position the product so as to cooperate with the EDM or CNC (Computer Numerical Control) machine tool to complete the product processing. That is, when the traction block 8 moves away from the product, it can squeeze and drive the product to move through the top groove of the clamping rod 10, and finally abut against the inner side wall of the groove 4 to complete the clamping positioning of the product. Then, the pressure plate 3 completes the positioning of the product, which can be adapted to the alignment positioning of products of different specifications.
[0040] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
