DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment one: please refer to Figures 1 to 2 A machining center workpiece height-adjusting fixing clamp, comprising a workbench 1, which provides support for other components.

[0024] The embodiment further comprises a workpiece clamping mechanism 2, two fixing plates 3, two adjusting plates 4 and two sets of locking assemblies 6.

[0025] The workpiece clamping mechanism 2 is movably arranged above the workbench 1 and is used for clamping and fixing the workpiece to be machined. Specifically, the workpiece clamping mechanism 2 comprises a workpiece placing plate 201 arranged in the horizontal direction, which is located above the workbench 1, and the workpiece can be placed on the top of the workpiece placing plate 201. The connecting frame 5 is fixed to the side surface of the workpiece placing plate 201. Two clamping plates 202 are arranged in the horizontal direction above the workpiece placing plate 201 and are used for clamping and fixing the workpiece. A plurality of adjusting screws 203 are fixed in parallel and at intervals at the bottom of each clamping plate 202, and a strip-shaped hole 204 corresponding to each adjusting screw 203 is formed in the workpiece placing plate 201. The adjusting screw 203 can move left and right along the strip-shaped hole 204, so as to adjust the distance between the two clamping plates 202 to adapt to workpieces of different lengths. Each adjusting screw 203 passes through the corresponding strip-shaped hole 204 in the vertical direction and is screw-connected with an adjusting nut 205 at the lower end. The workpiece is placed on the top of the workpiece placing plate 201, and then the adjusting screw 203 is slid left and right along the strip-shaped hole 204 to adjust the distance between the two clamping plates 202 to adapt to workpieces of different lengths. After the adjustment is completed, the adjusting nut 205 is tightened to move the clamping plate 202 downward to clamp and fix workpieces of different thicknesses.

[0026] In the embodiment, in order to avoid the workpiece placing plate 201 and the clamping plate 202 directly contacting the workpiece, soft pads can be fixed on the upper surface of the workpiece placing plate 201 and the lower surface of the clamping plate 202, so as to avoid the workpiece placing plate 201 and the clamping plate 202 directly contacting the workpiece and causing damage to the workpiece.

[0027] In addition, two fixed plates 3 are parallel and fixed on the top of the workbench 1 and located on both sides of the workpiece clamping mechanism 2. Two adjusting plates 4 are respectively located on the side of the two fixed plates 3 away from each other, and a connecting frame 5 passing through the corresponding fixed plate 3 is connected between each adjusting plate 4 and the workpiece clamping mechanism 2. Two sets of locking assemblies 6 are respectively arranged on each connecting frame 5, which are used to make the adjusting plate 4 and the fixed plate 3 in close contact.

[0028] Specifically, the connecting frame 5 is composed of a plurality of connecting rods which are parallel and fixed on the side of the workpiece clamping mechanism 2. Each connecting rod passes through the fixed plate 3 and the adjusting plate 4 in the horizontal direction, and an adjusting hole 7 is formed on the fixed plate 3 for the connecting rod to pass through. The connecting rod slides up and down in the adjusting hole 7, which can adjust the height of the workpiece clamping mechanism 2.

[0029] Preferably, the side of the fixed plate 3 close to the adjusting plate 4 is fixed with a first sawtooth structure, and the side of the adjusting plate 4 close to the fixed plate 3 is fixed with a second sawtooth structure which is engaged with the first sawtooth structure. When the adjusting plate 4 and the fixed plate 3 are in close contact, the cooperation of the first sawtooth structure and the second sawtooth structure makes the adjusting plate 4 and the fixed plate 3 not move up and down relative to each other, so that the workpiece can be stably supported, avoiding the situation that the workpiece falls due to insufficient friction.

[0030] In this embodiment, the locking assembly 6 includes a limiting plate 601 fixed to the outer end of the connecting rod, and a compression spring 602 is sleeved on each connecting rod between the limiting plate 601 and the adjusting plate 4. In the normal state, the compression spring 602 exerts an inward elastic force on the adjusting plate 4, so that the adjusting plate 4 can be in close contact with the fixed plate 3.

[0031] After the workpiece to be processed is fixed on the workpiece clamping mechanism 2, when the height of the workpiece needs to be adjusted, the adjusting plate 4 is pulled outward so that the first sawtooth structure is not engaged with the second sawtooth structure. At this time, the connecting rod moves up and down along the adjusting hole 7, which can adjust the height of the workpiece. After adjustment, the adjusting plate 4 is released, and under the action of the compression spring 602, the adjusting plate 4 is in close contact with the fixed plate 3, so that the first sawtooth structure is engaged with the second sawtooth structure, which can fix the height of the workpiece.

[0032] Embodiment two: please refer to Figures 3 to 4 The difference between this embodiment and embodiment one is:

[0033] The locking assembly 6 comprises a threaded groove arranged on the outer surface of the connecting rod, and a locking nut 604 is threadedly connected on the threaded groove. When the height of the workpiece needs to be adjusted, the locking nut 604 is loosened, and then the adjusting plate 4 is moved away from the fixed plate 3, so that the height of the workpiece can be adjusted. After the adjustment is completed, the locking nut 604 is tightened, so that the adjusting plate 4 is in close contact with the fixed plate 3, and the height of the workpiece is fixed.
