Description

Technical Field

[0001] The present application relates to the technical field of drilling and tapping equipment, and in particular to a workpiece fixing device for mold drilling and tapping. Background Art

[0002] Mold drilling and tapping refers to a method of using drilling and tapping tools to process holes in molds during mold manufacturing. Specifically, a drill is first used to pre-drill holes, and then a tapping tool is inserted into the drilled hole and rotated and pushed to form threads in the hole. Mold drilling and tapping can improve production efficiency and work accuracy, while also ensuring the quality and consistency of the holes. It is widely used in mold manufacturing, machining and other related fields.

[0003] With respect to the above-mentioned related technologies, the inventor believes that when drilling and tapping the mold, the mold needs to be clamped and fixed. The existing fixing method mainly uses two sets of clamps to fix the mold. However, in actual application, since the sizes of the molds are different, and the size of the clamps is fixed, if a larger mold is encountered, the vibration generated during the drilling and tapping process may cause the small clamps to be unable to effectively clamp and fix the mold, resulting in deviations in the drilling and tapping results.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that when encountering a large-sized mold, the vibration generated during the drilling and tapping process may cause the small clamping plate to be unable to effectively clamp the mold, resulting in deviations in the drilling and tapping results, the present application provides a workpiece fixing device for mold drilling and tapping.

[0006] The present application provides a workpiece fixing device for mold drilling and tapping, which adopts the following technical solution:

[0007] A workpiece fixing device for mold drilling and tapping comprises a base plate, two groups of clamping plates are arranged on the base plate, two groups of moving rods are arranged on the base plate, the clamping plates are fixedly mounted on the moving rods, and the clamping plates are provided with a first through hole and a second through hole.

[0008] Preferably, a guide groove is provided on the bottom plate, and the moving rod cooperates with the guide groove, and positive and negative screw rods cooperating with two groups of the moving rods are movably installed on the bottom plate.

[0009] Preferably, a rotating rod extending into the first through hole is rotatably mounted on each of the clamping plates, and a gear is fixedly mounted on each of the rotating rods.

[0010] Preferably, two groups of racks cooperating with the gear are movably arranged in the through hole 1, and the racks extend to the outside of the clamping plate and are respectively installed with a sub-plate 1 and a sub-plate 2.

[0011] Preferably, a movable plate extending into the second through hole is fixedly mounted on the first sub-plate and the second sub-plate, and a groove and a protrusion are respectively mounted on the movable plate.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By rotating the forward and reverse screw rods, the two sets of moving rods are driven to move in opposite directions, and then the two sets of clamping plates are driven to approach each other, so as to clamp and fix the mold. If a larger mold needs to be clamped and fixed, it is only necessary to rotate the rotating rod, and the rotating rod drives the gear to rotate, and the gear drives the two sets of racks to move in opposite directions, and the rack drives the sub-plate 1 and the sub-plate 2 to move in opposite directions, thereby increasing the distance between the sub-plate 1 and the sub-plate 2, so that it can clamp and fix larger molds.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a workpiece fixing device for mold drilling and tapping. Figure 1-2 A workpiece fixing device for mold drilling and tapping, comprising a base plate 1, two groups of clamping plates 2 are arranged on the base plate 1, two groups of moving rods 3 are arranged on the base plate 1, the clamping plates 2 are fixedly installed on the moving rods 3, the clamping plates 2 are both provided with through holes 1 and 2, a guide groove 4 is provided on the base plate 1, and the moving rod 3 cooperates with the guide groove 4, and a positive and negative screw rod 5 cooperating with the two groups of moving rods 3 is movably installed on the base plate 1;

[0021] By adopting the above technical solution, the forward and reverse screws 5 are rotated, and the two groups of moving rods 3 can be driven to move in opposite directions through the guiding effect of the guide grooves 4, thereby driving the two groups of clamping plates 2 to approach each other, thereby clamping and fixing the mold.

[0022] Reference Figure 1-4 , the clamping plate 2 is rotatably mounted with a rotating rod 6 extending into the through hole 1, and the rotating rod 6 is fixedly mounted with a gear 7, and two sets of racks 8 cooperating with the gear 7 are movably arranged in the through hole 1, and the racks 8 extend to the outside of the clamping plate 2 and are respectively mounted with a sub-plate 1 9 and a sub-plate 2 10, and the sub-plates 1 9 and 10 are fixedly mounted with a movable plate 13 extending into the through hole 2, and the movable plate 13 is respectively mounted with a groove 11 and a convex block 12;

[0023] By adopting the above technical solution, if it is necessary to clamp and fix a larger mold, it is only necessary to rotate the rotating rod 6, the rotating rod 6 drives the gear 7 to rotate, the gear 7 drives the two sets of racks 8 to move in the opposite direction, and the rack 8 drives the sub-plate 1 9 and the sub-plate 2 10 to move in the opposite direction, thereby increasing the distance between the sub-plate 1 9 and the sub-plate 2 10, so that it can clamp and fix a larger mold. Through the action of the convex groove and the convex block 12, the sub-plate 1 9 and the sub-plate 2 10 can be tightly connected to prevent the sub-plate 1 9 and the sub-plate 2 10 from offsetting when the mold is fixed, resulting in deviations in the drilling and tapping results.

[0024] The implementation principle of a workpiece fixing device for mold drilling and tapping in an embodiment of the present application is as follows: when the mold needs to be clamped and fixed, first rotate the forward and reverse screw rods 5, and the forward and reverse screw rods 5 drive the two groups of moving rods 3 to move in opposite directions, and then drive the two groups of clamping plates 2 to approach each other, thereby clamping and fixing the mold. If it is necessary to clamp and fix a larger mold, it is only necessary to rotate the rotating rod 6, and the rotating rod 6 drives the gear 7 to rotate, and the gear 7 drives the two groups of racks 8 to move in opposite directions. The rack 8 drives the sub-plate 1 9 and the sub-plate 2 10 to move in opposite directions, thereby increasing the distance between the sub-plate 1 9 and the sub-plate 2 10, so that it can clamp and fix a larger mold.
