[0023] like Figure 1-4 As shown, an embodiment of the present application proposes a positioning fixture for hardware processing, including a base 1, a clamping seat 2, a moving device 3, a locking device 4, an unlocking device 5 and two clamping devices 6, the clamping seat 2 is stacked on the base 1, the moving device 3 connects the base 1 and the clamping seat 2, the locking device 4 is arranged in the base 1 and connected to the moving device 3, the unlocking device 5 is arranged in the moving device 3 and connected to the locking device 4, and the two clamping devices 6 are symmetrically arranged on both sides of the clamping seat 2 facing away from the base 1.

[0024] The positioning fixture for hardware processing disclosed in the present utility model comprises a base 1, a clamping seat 2, a moving device 3, a locking device 4, an unlocking device 5 and two clamping devices 6. The positioning fixture is installed on a processing machine tool. The base 1 is connected and fixed to the processing machine tool. The clamping seat 2 is stacked above the base 1 and is driven by the moving device 3 to move relative to the base 1. The locking device 4 locks the moving device 3 to limit the relative movement of the clamping seat 2 and the base 1. The unlocking device 5 releases the lock of the locking device 4. The two clamping devices 6 are locked. Device 6 is provided on the clamping seat 2, and the two clamping devices 6 move toward one side close to each other to clamp and fix the hardware. When the hardware is taken and placed on the clamping seat 2, the clamping seat 2 moves relative to the base 1 through the moving device 3, that is, the clamping seat 2 drives the hardware away from the machine tool before taking and placing the hardware, avoiding the turning tool or drill of the machine tool threatening the safety of the operator when taking and placing hardware on the machine tool. The positioning fixture disclosed in this application reduces the restrictions of the machine tool space on taking and placing hardware, and the operator can take and place the hardware away from the turning tool or drill, which is safer.

[0025] The moving device 3 includes a first slide groove 31 and a first slider 32. The first slide groove 31 is provided on the side of the base 1 facing the clamping seat 2. The first slider 32 is slidably installed in the first slide groove 31 and is connected to the clamping seat 2. The locking device 4 includes two locking mechanisms. The two locking mechanisms are respectively provided on both sides of the first slide groove 31. The first slider 32 slides in the first slide groove 31 to move the clamping seat 2 relative to the base 1. The clamping seat 2 drives the two clamping devices 6 to move away from the machine tool synchronously, so that hardware can be taken in and out outside the machine tool, which is safer.

[0026] The locking mechanism includes a first locking hole 41, a second locking hole 42, a receiving groove 43, a sleeve 44, a guide rod 45, a locking block 46 and a spring 47. The first locking hole 41 and the second locking hole 42 are respectively provided on the first slider 32 along the length direction of the first slider 32, the receiving groove 43 is provided on the first slide groove 31, one end of the sleeve 44 is connected to the receiving groove 43, one end of the guide rod 45 is passed through the sleeve 44, and the other end of the guide rod 45 is connected to the locking block 46, and the spring 47 is sequentially sleeved on the outer sides of the sleeve 44 and the guide rod 45. The locking block 46 is provided with two first inclined surfaces 48 on the side facing the first slider 32. The two first inclined surfaces 48 are respectively provided on both sides of the locking block 46 along the length direction of the first slide groove 31. The sleeve 44 and the guide rod 45 cooperate to The locking block 46 plays a guiding role, limiting the movement of the locking block 46 along the length direction of the accommodating groove 43, and the elastic force of the spring 47 pushes the locking block 46 into the first locking hole 41 or the second locking hole 42 respectively. When the locking block 46 is inserted into the first locking hole 41, the clamping seat 2 is reset to the bottom of the machine tool turning tool or drilling tool; when the locking block 46 is inserted into the second locking hole 42, the clamping seat 2 is away from the machine tool, and the two moving positions of the clamping seat 2 are limited by the locking device 4. On the one hand, the clamping seat 2 and the base 1 are locked to limit the relative movement therebetween, and on the other hand, the clamping seat 2 is prevented from detaching from the base 1 after excessive movement on the base 1; in addition, the first inclined surface 8 plays a certain guiding role when the locking block 46 is inserted into the first locking hole 41 or the second locking hole 42, which facilitates alignment and plugging.

[0027] The unlocking device 5 includes two communicating grooves 51, two inserting rods 52 and a connecting rod 53. The two communicating grooves 51 are respectively provided on both sides of the first sliding block 32. Any of the communicating grooves 51 is respectively connected to the first locking hole 41 and the second locking hole 42. The two inserting rods 52 are respectively inserted into the two communicating grooves 51 in a one-to-one manner. The connecting rod 53 is connected to the two inserting rods 52. One end of the inserting rod 52 is provided with a second inclined surface 54 corresponding to the first inclined surface 48. Pushing the connecting rod 53, the two inserting rods 52 are synchronously driven to move along the two communicating grooves 51 respectively. The second inclined surface 54 cooperates with the first inclined surface 48 to convert the lateral thrust exerted on the locking block 46 into a longitudinal component force, thereby compressing the spring 47 and causing the locking block 46 to disengage from the first locking hole 41 or the second locking hole 42, thereby releasing the lock of the locking device 4.

[0028] The positioning fixture also includes a handle 7, which is provided on one end of the first slider 32. The operator can push and pull the first slider 32 through the handle 7 without directly contacting the clamping seat 2 or the base 1, to prevent the operator from being pinched when the two move relative to each other.

The connecting block 642 is connected to the other end of the screw 641, and the rotating rod 643 is passed through the connecting block 642. The connecting seat 63 is slidably connected to the clamping seat 2 through the cooperation of the second sliding block 62 and the second sliding groove 21. The screw 641 is threadedly connected to the fixing plate 61, and the screw 641 is rotatably connected to the connecting seat 63. Rotating the rotating rod 643 drives the screw 641 to rotate on the fixing plate 61, thereby pushing the connecting seat 63 to move along the second sliding groove 21, driving the two clamping blocks 65 on the two clamping devices 6 to approach each other to clamp the fixed hardware. In addition, the clamping block 65 is detachably connected to the connecting seat 63 through the quick-install mechanism 66. The quick-install mechanism 66 includes a buckle provided on the clamping block 65 and a slot provided on the connecting seat 63, which can quickly replace the corresponding clamping block 65 according to hardware of different shapes and sizes, and is more practical.

[0030] The rotating connection assembly 644 includes a rotating ring 645, a first clamping member 646, a second clamping member 647, a plug-in slot 648 and a plug-in block 649.
