Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures, and in particular to a positioning fixture for processing hardware parts. Background Technology

[0002] When processing hardware parts, computer numerical control (CNC) machine tools are usually used. The computer decodes the code, so that the machine tool can perform the prescribed actions and process the blank material into semi-finished parts through cutting tools.

[0003] When hardware parts are processed inside a computer numerical control (CNC) machine tool, a motor or cylinder is usually used to drive the relative movement of the clamping plate to hold and fix the hardware parts, so that the hardware parts are processed in a stable state inside the CNC machine tool.

[0004] Fixtures are typically fixed inside CNC machine tools using mounting brackets. To improve the safety of CNC machine tool operation, a protective shell is installed on the outside of the machine tool. A door panel is provided on the front of the shell, allowing the hardware on the fixture to be inspected or replaced by opening the door panel. However, due to the limitations of the protective shell, operators need to bend over and reach into the shell when inspecting or replacing hardware, which can cause the internal components of the CNC machine tool to bump or scratch the operator. It is also inconvenient to remove the fixture for use when inspecting or replacing hardware. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-4 The positioning fixture shown includes a machine tool 1, an installation plate 2 installed inside the machine tool 1, a support seat 3 slidably connected to the top of the installation plate 2, the support seat 3 being slidably connected to the top of the installation plate 2 via a slide rail, and an electric clamp 4 installed on the top of the support seat 3. The electric clamp 4 consists of two cylinders and two clamping plates. The cylinders are installed on the top of the support seat 3, and the output end of the cylinders is connected to the clamping plates for transmission. The two cylinders push the two clamping plates to move relative to each other, thereby clamping the hardware parts.

[0030] In particular, the mounting plate 2 is provided with a positioning component 5 for locking the position of the support seat 3. The positioning component 5 includes a locking plate 51, a lifting component 52, and a reset component 53. The top of the mounting plate 2 is symmetrically provided with mounting holes that match the locking plate 51. The top of the locking plate 51 is fixedly connected with first locking teeth 54 at equal intervals. The bottom of the support seat 3 is provided with a groove that matches the locking plate 51. The top of the inner wall of the groove is fixedly connected with second locking teeth 55 that cooperate with the first locking teeth 54 at equal intervals. The lifting component 52 is located inside the mounting plate 2 and is used to push the locking plate 51 up to lock the support seat 3. When the locking plate 51 rises, the first locking tooth block 54 and the second locking tooth block 55 on the top of the locking plate 51 engage, thereby locking the support seat 3. There are two locking plates 51 on the mounting plate 2, which lock the support seat 3 in the withdrawn position and the support seat 3 in the reset position. The reset component 53 is located at the bottom of the side of the locking plate 51. When the lifting component 52 stops lifting the locking plate 51, the reset component 53 drives the locking plate 51 to fall, causing the first locking tooth block 54 and the second locking tooth block 55 on the top of the locking plate 51 to separate. The support seat 3 can then drive the electric clamp 4 to slide on the mounting plate 2.

[0031] Furthermore, the lifting assembly 52 includes a connecting plate 521, a support block 522, and a lifting roller 523. A slot is provided at the bottom of the mounting plate 2, the connecting plate 521 is slidably connected to the inside of the slot, the support block 522 is fixedly connected to the bottom of the locking plate 51, and the lifting roller 523 is rotatably mounted on the top of the connecting plate 521. An inclined slope is provided on one side of the bottom of the support block 522. Figure 4 As shown, when the connecting plate 521 drives the lifting roller 523 to slide from the inclined surface of the support block 522 to the horizontal bottom of the support block 522, the lifting roller 523 can lift the locking plate 51 to a certain height. The top of the connecting plate 521 is provided with a mating groove 524 that matches the support block 522. The top of the inner cavity of the mating groove 524 is fixedly connected to a fixed shaft 525. The outer wall of the fixed shaft 525 is rotatably sleeved with the lifting roller 523. A servo motor 527 is installed on the front of the mounting plate 2. The output end of the servo motor 527 is connected to a drive screw 526. The outer wall of the drive screw 526 is threadedly sleeved with the connecting plate 521. The servo motor 527 drives the drive screw 526 to rotate, which in turn causes the drive screw 526 to drive the connecting plate 521 to slide in the slot. A first slider 528 is fixedly connected to the side of the connecting plate 521. The outer wall of the first slider 528 is horizontally slidably connected to the mounting plate 2. The first slider 528 can ensure the stability of the horizontal sliding of the connecting plate 521 in the slot.

[0032] Furthermore, the reset assembly 53 includes a second slider 531 and a reset spring 534. The second slider 531 is fixedly connected to the bottom of the side of the locking plate 51. The bottom of the mounting plate 2 has a connecting groove 532 that matches the second slider 531. The second slider 531 can ensure the stability of the locking plate 51 sliding vertically up and down in the mounting hole. The reset spring 534 is disposed inside the connecting groove 532. A connector 533 is fixedly connected to one side of the second slider 531. A fixing rod 535 is fixedly connected to the top of the inner wall of the connecting groove 532. The outer wall of the fixed rod 535 is slidably sleeved with the return spring 534, and the outer wall of the fixed rod 535 is slidably sleeved with the connector 533. The return spring 534 is located at the top of the connector 533. When the lifting roller 523 slides to one side of the inclined surface of the support block 522, the return spring 534 can drive the locking plate 51 to descend through the connector 533 and the second slider 531, so that the first locking tooth block 54 and the second locking tooth block 55 at the top of the locking plate 51 are separated. The servo motor 527 is electrically connected to the external power supply through the internal switch of the control box on the machine tool 1.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
