Description

Technical Field

[0001] The utility model relates to the technical field of die-casting, in particular to a die-casting jig quick positioning component. Background Art

[0002] Jigs are a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. They are mainly used as a tool to assist in controlling position or movement (or both). Jigs can be divided into three categories: process assembly jigs, project test jigs and circuit board test jigs. The manufacturing of die-casting parts is relatively easy, and the unit cost increment is very low, so die-casting is the most widely used of various casting processes. Before die-casting, quickly positioning the jig can save die-casting time and reduce the unqualified rate of the finished product.

[0003] After searching, the application number CN202410083475.5 discloses a device with automatic positioning, including a device bracket, a placement table, an infrared sensing device and a limit clamp. The bottom of the device bracket is connected to the device table, and a placement table is arranged above the top of the device table. A bidirectional screw is connected inside the placement table, and a fourth rotation drive mechanism is installed at the end of the bidirectional screw. A fourth moving block is symmetrically sleeved on the outside of the bidirectional screw. The stable positioning of the die-casting is achieved by the arrangement of the fourth rotation drive mechanism, the bidirectional screw and the first moving block.

[0004] The existing positioning components still need to actively fix and clamp the workpiece, and the rigid clamping can easily cause damage to the fixture, reducing the service life of the fixture. Utility Model Content

[0005] The purpose of the utility model is to provide a die-casting jig rapid positioning component to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a die-casting jig rapid positioning component, including a support seat, a press is installed on the top of the support seat, and the press performs pressure die-casting on the jig, and four groups of positioning components are installed at intervals on the upper end of the support seat, and the four groups of positioning components are evenly distributed around the jig to position the jig, and the positioning components include a main positioning component and a secondary positioning component. When the main positioning component is moved away from the outer wall of the jig by the thrust of the outer wall of the jig, the secondary positioning component moves toward the outer wall of the jig, thereby accelerating the fixation of the jig.

[0007] As a further preference, the support seat includes a support plate, the upper end surface of the support plate is fixedly connected to a U-shaped mounting plate, one side of the upper end surface of the support plate is fixedly connected to an L-shaped mounting plate, and the L-shaped mounting plate is arranged at a corresponding position of the opening of the U-shaped mounting plate.

[0008] As a further preference, the main positioning component includes a mounting sleeve, a positioning slider is slidably connected to the inner wall of the mounting sleeve, one end of the positioning slider extends out of the mounting sleeve and is fixedly connected to a first elastic pad, one end of the positioning slider facing away from the first elastic pad is fixedly connected to an elastic component, and one end of the elastic component facing away from the positioning slider is fixedly connected to the inner wall of the mounting sleeve.

[0009] As a further preference, the auxiliary positioning assembly includes a sliding sleeve, in which an L-shaped slider is slidably connected, one end of the L-shaped slider extending out of the sliding sleeve is fixedly connected to a second elastic pad, and auxiliary tooth grooves are symmetrically provided on one side of the L-shaped slider adjacent to the positioning slider.

[0010] As a further preference, a main tooth groove is provided on a side of the positioning slider adjacent to the L-shaped slider, the main tooth groove is meshedly connected with a driving gear, and the driving gear is also meshedly connected with the auxiliary tooth groove.

[0011] Through the above technical solution, the die-casting fixture quick positioning assembly provided by the utility model has the following benefits:

[0012] The utility model arranges a positioning component and places the jig in an area surrounded by four groups of positioning components. The outer wall of the jig pushes the first elastic pad to deform, and then pushes the positioning slider to compress the elastic component and move it toward the inner wall of the mounting sleeve, so that the distance between the two symmetrical groups of main positioning components in the corresponding direction is adjusted according to the length and width of the jig. When the positioning slider moves along the inner wall of the mounting sleeve in a direction away from the outer wall of the jig, the positioning slider engages the driving gear through the main tooth groove to rotate, and the rotating driving gear engages the secondary tooth groove to make the L-shaped slider move along the inner wall of the sliding sleeve toward the outer wall of the jig. The reaction force of the compressed elastic component acts on the positioning slider to support the outer wall of the jig. The outer wall of the jig is supported and clamped by the elastic component and the second elastic pad at the same time. The first elastic pad and the second elastic pad avoid damage to the outer wall of the jig during positioning and clamping, so that the positioning of the jig can be quickly realized and the stability of the jig can be improved.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model is further described in detail with reference to the accompanying drawings.

[0021] See also Figure 1 - Figure 5 , a die-casting jig quick positioning assembly provided by the utility model, includes a press 1, a support seat 2 and a positioning assembly 3.

[0022] Among them, see Figure 1 - Figure 3 The support seat 2 includes a support plate 22, a U-shaped mounting plate 21 is fixedly connected to the upper end surface of the support plate 22, an L-shaped mounting plate 23 is fixedly connected to the edge of the upper end surface of the support plate 22, the L-shaped mounting plate 23 is arranged at a position corresponding to the opening of the U-shaped mounting plate 21, a press 1 is installed on the top of the L-shaped mounting plate 23, and the press 1 performs die-casting on the jig at the upper end of the support plate 22. There are four groups of positioning components 3, and two groups are symmetrically installed on the inner wall of the area surrounded by the U-shaped mounting plate 21 and the L-shaped mounting plate 23. The positioning components 3 include a main positioning component 31 and an auxiliary positioning component 32. When the outer wall of the jig pushes one end of the main positioning component 31 to move in a direction away from the outer wall of the jig, the auxiliary positioning component 32 moves along the direction close to the jig adjacent to the side of the jig, thereby positioning and clamping the jig.

[0023] It should be noted that the four groups of positioning components 3 correspond to the front, back, left and right end faces of the fixture respectively, and the lower end of the press 1 is located on the central axis of the area surrounded by the four groups of positioning components 3.

[0024] For details, please refer to Figure 4The cam 314 is provided to the rear end of the fixing member 316 so that the fixing member 316 can be easily moved after the fixing member 316 is in a state of being easily moved.

[0025] It should be noted that the outer wall size of the positioning slider 312 is the same as the inner wall size of the installation sleeve 311 , and the positioning slider 312 is connected to the inner wall of the installation sleeve 311 in a frictionless sliding manner.

[0026] For details, please refer to Figure 5 In order to improve the positioning stability of the auxiliary positioning component 32, the auxiliary positioning component 32 includes a sleeve 321, and an adjacent end of the sleeve 321 is slidably connected with an L-shaped slider 325, and one end of the L-shaped slider 325 extends out of the sleeve 321 and is fixedly connected with the L-shaped slider 325. The L-shaped slider 325 is provided with an auxiliary tooth groove 323 on the side close to the main positioning component 31, and the auxiliary tooth groove 323 is meshed with a driving gear 324. When the driving gear 324 rotates, it meshes with the auxiliary tooth groove 323 to drive the L-shaped slider 325 to move.

[0027] It should be noted that the lower end of the driving gear 324 is rotatably connected to a support rod, and one end of the support rod away from the driving gear 324 is fixedly connected to the upper end surface of the support plate 22 .

[0028] For details, please refer to Figure 4 and Figure 5In order to realize that the main positioning component 31 and the auxiliary positioning component 32 simultaneously position and clamp the fixture, a main tooth groove 313 is opened on the side of the positioning slider 312 close to the auxiliary positioning component 32, and the main tooth groove 313 is meshed and connected with the driving gear 324. When the fixture is installed, the outer wall of the fixture pushes the positioning slider 312 to move away from the outer wall of the fixture, and the positioning slider 312 meshes with the driving gear 324 through the main tooth groove 313 to make the driving gear 324 rotate, and the rotating driving gear 324 meshes with the auxiliary tooth groove 323, so that the L-shaped slider 325 moves in the opposite direction of the positioning slider 312, so that the L-shaped slider 325 and the positioning slider 312 supported by the reaction force of the elastic component 315 can simultaneously position and clamp the fixture, thereby improving the stability of clamping. In addition, the positioning slider 312 is pushed by the fixture to move and directly drives the L-shaped slider 325 to move in the opposite direction through the driving gear 324, thereby reducing the influence of the fluctuation generated when the elastic component 315 absorbs the thrust on the fixture, so that the elastic component 315 can quickly reach a stable state, thereby improving the positioning response speed.

[0029] It should be noted that when the positioning slider 312 is not subjected to external force, the distance A between the second elastic pad 322 and the fixture installation area is smaller than the distance B between the first elastic pad 314 and the fixture installation area. The applicable size range of the positioning fixture is affected by BA and the elastic deformation of the first elastic pad 314 and the second elastic pad 322. When the fixture is in the positioning state, the outer wall of the fixture contacts the first elastic pad 314 and the second elastic pad 322 at the same time and causes the first elastic pad 314 and the second elastic pad 322 to deform.

[0030] Principle: The jig is placed in the area surrounded by four groups of positioning components 3. The outer wall of the jig pushes the first elastic pad 314 to deform, and then pushes the positioning slider 312 to compress the elastic component 315 and move along the inner wall of the mounting sleeve 311. The distance between the two symmetrical main positioning components 31 is expanded according to the width and length of the jig. The reaction force of the compressed elastic component 315 acts on the positioning slider 312, so that the two adjacent groups of positioning sliders 312 limit the jig. At the same time, the main tooth groove 313 engages the driving gear 324 to rotate, and the rotating driving gear 324 engages the auxiliary tooth groove 323, thereby driving the L-shaped slider 325 to move along the inner wall of the sleeve 321 toward the outer wall of the jig, so as to quickly position and clamp the jig. The press 1 works to pressurize the positioned jig to achieve die-casting.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
