Description

Technical Field

[0001] This utility model relates to the technical field of drilling holes in kitchen utensil handles, and in particular to a drilling machine. Background Technology

[0002] The front end of the handle of kitchen utensils is usually drilled with holes. The purpose of drilling holes is to make it easier to fix the body of the kitchen utensils to the handle. The usual method of fixing is to use a bolt to pass through the hole and then connect it to the body of the kitchen utensils by thread.

[0003] Existing drilling methods involve bending the stainless steel handle into an arc shape before drilling, such as... Figure 4 During the drilling process, the worker places the stainless steel plate onto the positioning roller, then presses the stainless steel plate firmly, and then the drilling machine drills the hole.

[0004] This drilling method has certain drawbacks. The main drawback is that it requires workers to apply force to press the handle of the kitchen utensil, which poses a certain safety risk. When the drill bit of the drilling machine comes into contact with the stainless steel plate, it may exert a pushing force on the stainless steel plate, causing it to retract. This can easily cause the stainless steel plate to cut the worker's hand. Furthermore, if the worker is not careful, this drilling method can easily lead to misalignment of the hole.

[0005] Therefore, this application provides a punching machine that can improve the safety of punching holes in kitchen utensil handles, while also improving the accuracy of the punching. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a punching machine to solve the problems of safety risks and low punching accuracy when punching holes in kitchen utensil handles in the prior art described in the background.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A drilling machine includes a U-shaped crossbeam plate, the lower end of which is fixedly connected to a base plate via a first support plate; an Ω-shaped positioning post fixedly connected to the lower end wall of the crossbeam plate; wherein the positioning post has a through-hole; a push ring movably and slidably sleeved on the positioning post; a lifting frame vertically mounted on the upper end wall of the crossbeam plate; a drilling machine fixedly connected to the lifting frame, the output end of which has a drill bit facing the through-hole; and two arc-shaped pressure plates located on both sides of the lifting frame for pressing stainless steel plates onto the positioning post.

[0009] Furthermore: Limiting plates are fixedly connected to the positions of the two pressure plates on the lifting frame, and the two pressure plates are fixedly connected to the limiting plates by springs.

[0010] Furthermore: a lifting cylinder is fixedly connected to the upper wall of the crossbeam plate, and the output end of the lifting cylinder is fixedly connected to the lifting frame.

[0011] Furthermore: two parallel mounting plates are fixedly connected to the lower surface of the positioning column, and ball screw modules are provided on the two mounting plates. A movable plate is fixedly connected to the push ring, and the movable plate is threadedly connected to the ball screw of the ball screw module.

[0012] Furthermore, a positioning ring is fixedly connected to the upper wall of the crossbeam plate. The positioning ring is fixedly connected to the bottom plate through the second support plate. The positioning post passes through the positioning ring and is fixedly connected to the inner wall of the positioning ring.

[0013] The advantages of adopting the above technical solutions are:

[0014] This application uses the cylindrical part of the positioning column to fit the bent stainless steel plate. Then, the moving plate drives the push ring to move and position the stainless steel plate. Then, the pressure plate presses the stainless steel plate onto the positioning column before drilling. Because of the presence of the pressure plate, the traditional manual tightening operation can be eliminated, which can improve safety and drilling accuracy. Attached Figure Description

Implementation

[0021] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3In this first embodiment, a drilling machine includes a U-shaped crossbeam plate 20, the lower end of which is fixedly connected to a base plate 10 via a first support plate 21; an Ω-shaped positioning post 40, fixedly connected to the lower end wall of the crossbeam plate 20; wherein the positioning post 40 has a through-hole 41; a push ring 50, movably slidably sleeved on the positioning post 50; a lifting frame 60, liftably mounted on the upper end wall of the crossbeam plate 20; a drilling machine 70, fixedly connected to the lifting frame 60, the output end of the drilling machine 70 having a drill bit 71 facing the through-hole 41; and two arc-shaped pressure plates 80, respectively located on both sides of the lifting frame 60, used to press stainless steel plates onto the positioning post 40.

[0023] This embodiment is implemented as follows:

[0024] In use, the bent stainless steel plate is first placed on the positioning post 40, so that the stainless steel plate contacts the push ring 50. Then the push ring 50 moves, pushing the stainless steel plate until the drilling position of the stainless steel plate moves to the position of the feed hole 41. Then the push ring 50 stops, and the pressure plate 80 moves downward, pressing the stainless steel plate onto the positioning post 40, thus fixing the stainless steel plate. Then the lifting frame 60 drives the drilling machine 70 to move downward, and the drill bit 71 drills holes in the stainless steel plate. After drilling, the drill bit will pass through the stainless steel plate and enter the feed hole 41.

[0025] As an optimized solution of this embodiment, the lifting frame 60 is fixedly connected to the positions of the two pressure plates 80 respectively, and the two pressure plates 80 are fixedly connected to the pressure plates 82 by springs 81 respectively. In order to further improve the stability of the springs 81, a sliding rod 83 is fixedly connected to the pressure plate 80, which slides through the springs 81 and the pressure plates 82. The sliding rod 83 can increase the stability of the springs 81 and prevent the springs 81 from bending and deforming.

[0026] In this optimized solution, when the lifting frame 60 moves downward, the pressure plate 80 will contact the stainless steel plate first, and the spring 81 will be compressed. The reaction force of the spring 81 can press the stainless steel plate onto the pressure plate 80, thereby fixing the stainless steel plate.

[0027] As an optimized solution of this embodiment, a lifting cylinder 61 is fixedly connected to the upper wall of the crossbeam plate 20. The output end of the lifting cylinder 61 is fixedly connected to the lifting frame 60. In order to improve the stability of the vertical movement of the lifting frame 60, a number of guide rods 62 that slide through the upper wall of the crossbeam plate 20 are fixedly connected to the lifting frame 60.

[0028] In this optimized design, the lifting cylinder 61 can drive the lifting frame 60 to move vertically on the crossbeam plate 20.

[0029] As an optimized solution of this embodiment, the lower surface of the positioning column 40 is fixedly connected to two parallel mounting plates 53, and ball screw modules 52 are provided on the two mounting plates 53. A movable plate 51 is fixedly connected to the push ring 50, and the movable plate 51 is threadedly connected to the ball screw of the ball screw module 52.

[0030] In this optimized solution, the ball screw module 52 can drive the moving plate 51 to move on the ball screw of the ball screw module 52, thereby driving the push ring 50 to move.

[0031] As an optimized solution of this embodiment, a positioning ring 30 is also fixedly connected to the upper wall of the crossbeam plate 20. The positioning ring 30 is fixedly connected to the bottom plate 10 through the second support plate 31. The positioning column 40 passes through the positioning ring 30 and is fixedly connected to the inner wall of the positioning ring 30.

[0032] This optimized solution increases the support force on the positioning column 40 and the crossbeam plate 20 through the positioning ring 30, thereby improving the stability of the equipment.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
