[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figure 1 and Figure 2 This utility model provides a leather carving punch that facilitates the replacement of drill bits with different diameters. It includes a workbench 1 and a through hole 33. A pad 2 is fixedly connected to the top of the workbench 1, and a leather carving product 4 is placed on the top of the pad 2. The pad 2 has a symmetrical structure on both sides, and a guide groove 22 is formed between the two pads 2. A marking line 21 is provided on the top surface of the pad 2.

[0019] In this embodiment, since the upper surface of the through hole 33 also has a corresponding straight line, when the sliding plate 31 is moved, the alignment of the straight line with the marking line 21 is used to determine the position of the through hole 33, thus ensuring that the central axis of the through hole 33 coincides with the central axis of the opening rod 10.

[0020] Please see Figure 2 and Figure 3The pad 2 has an alignment module 3 that slides inside. The alignment module 3 includes a sliding plate 31 that is inserted into the pad 2. Guide strips 32 are fixedly installed on both outer walls of the sliding plate 31. The guide strips 32 also slide inside the guide groove 22, ensuring the stability and accuracy of the movement of the sliding plate 31. Several through holes 33 of different diameters are provided above the sliding plate 31. Perforated liner plates 34 are fixedly connected to both the front and rear sides of the pad 2. Locking bolts 35 are threaded into the perforated liner plates 34. The bottom end of the locking bolts 35 abuts against the upper surface of the guide strips 32.

[0021] In this embodiment, when using perforated rods 10 with different hole diameters, the position of the through hole 33 with the corresponding hole diameter needs to be adjusted. Specifically, the operator first loosens the locking bolt 35, the bottom end of the locking bolt 35 separates from the guide strip 32, and then pulls the sliding plate 31 so that the sliding plate 31 slides inside the guide groove 22. After the position of the through hole 33 is aligned with the vertical position of the perforated rod 10, the locking bolt 35 is rotated so that the bottom end of the locking bolt 35 abuts against the guide strip 32, thereby locking the position of the sliding plate 31. In the above scheme, it should be noted that since the hole-punching rod 10 is used for vertical drilling, during the actual locking process of the sliding plate 31, only one locking bolt 35 is needed to firmly fix the sliding plate 31, that is, the position of the sliding plate 31 will not shift during the drilling process.

[0022] Please see Figure 1 and Figure 4 A support arm 5 is fixedly installed on the top of the workbench 1. A connecting seat 51 connected to the workbench 1 is provided at the bottom of the support arm 5, and a mounting ring 52 for fixing the impact cylinder 6 is fixedly provided at the top of the support arm 5. In this embodiment, the support arm 5 has an L-shaped structure. The top of the support arm 5 is located directly above the workbench 1. The central axis of the mounting ring 52 is vertically perpendicular to the center of the workbench 1. The support arm 5 is fixedly connected to the back of the workbench 1 by connecting seat 51 and bolts.

[0023] Please see Figure 4 and Figure 5 An impact cylinder 6 is provided above the support arm 5. A lifting column 61 is provided inside the impact cylinder 6 via a piston plate. An outwardly expanding protruding ring 62 is fixedly provided on the outside of the lifting column 61. A bottom cover 63 is installed at the bottom of the lifting column 61 via a connector 9.

[0024] In this embodiment, a socket is provided below the bottom cover 63. The socket has a regular hexagonal structure, which matches the shape of the plug 101, making it easy for the plug 101 to be installed inside the bottom cover 63. The protruding ring 62 ensures that when the lifting column 61 moves up and down, it drives the protruding ring 62 to move synchronously, ensuring that the protruding ring 62 is always in contact with the conductive strip 83, thus ensuring the power transmission and keeping the energized coil 84 in a powered state.

[0025] Please see Figure 4 and Figure 5 A magnetic suction assembly 8 is provided below the impact cylinder 6, and a connector 9 is provided below the magnetic suction assembly 8. The magnetic suction assembly 8 is used to fix and attract the perforated rod 10. The magnetic suction assembly 8 includes a mounting bracket 81 fixed on the bottom outer wall of the support arm 5, and a sleeve 82 is fixedly provided at the bottom end of the mounting bracket 81 and sleeved on the outside of the lifting column 61. Several annularly distributed conductive strips 83 are fixedly provided inside the sleeve 82. One side of the convex ring 62 slides in contact with the conductive strip 83. An energized coil 84 is embedded and installed inside the lower part of the lifting column 61.

[0026] In this embodiment, the electrical energy of the conductive strip 83 is transmitted to the energized coil 84 through the convex ring 62. The coil 84 is fixed to the bottom of the support arm 5 by the mounting bracket 81, and the sleeve 82 is fixed to the bottom end of the mounting bracket 81. The sleeve 82 is movably sleeved on the outside of the lifting column 61. As the lifting column 61 moves up and down, it ensures that the convex ring 62 and the conductive strip 83 are always in contact. It should be noted that the energized coil 84 generates magnetic attraction when energized, which can attract and fix the plug 101. This is also a commonly used technical means in the prior art, and will not be described in detail here.

[0027] Please see Figure 5 and Figure 6 A perforated rod 10 is inserted into the lower part of the connector 9. The perforated rod 10 includes a plug 101 inserted into the lower part of the bottom cover 63, and an extension rod 102 is fixedly provided at the bottom of the plug 101. A punch 103 is provided at the bottom end of the extension rod 102.

[0028] In this embodiment, it should be noted that the hole-opening rod 10 mentioned in this application is a drill bit, and the drill bit described in the text is also the hole-opening rod 10. By using the punch 103 to contact the leather carving, a hole with a specific diameter can be formed on the leather carving to realize the drilling operation on the leather carving. The extension rod 102 is used to connect the plug 101 and the punch 103. The three are integrally formed structures. The plug 101 is used to realize the installation of the hole-opening rod 10 at the bottom of the lifting column 61.

[0029] Please see Figure 5 and Figure 6A placement rack 7 is fixedly installed on one side of the support arm 5, and several perforated rods 10 are placed on the placement rack 7 when not in use. Several placement slots 71 are provided on one side of the placement rack 7, and magnetic blocks 72 corresponding to the placement slots 71 are provided on the top of the placement rack 7. A card holder 73 connected to the support arm 5 is fixedly installed on the back of the placement rack 7, and the placement rack 7 is installed on the support arm 5 by the card holder 73 and bolts.

[0030] In this embodiment, the placement rack 7 is used to store and place multiple perforated rods 10. The extension rod 102 is inserted into the placement slot 71, and the plug 101 is located above the placement rack 7. At the same time, the magnetic block 72 can be used to attract and position the plug 101, ensuring the stability of the perforated rods 10 on the placement rack 7. People only need to apply a little force to remove the perforated rods 10 from the placement rack 7.

[0031] The working principle and usage process of this utility model are as follows: First, the operator removes the perforated rod 10 from the placement rack 7 and inserts the plug 101 into the inside of the bottom cover 63, thereby realizing the installation of the perforated rod 10 at the bottom of the lifting column 61. After the perforated rod 10 is placed, the magnetic suction component 8 is energized. At this time, the energized coil 84 generates magnetism, which can fix and attract the plug 101, so that it is fixed inside the bottom cover 63. Next, before drilling holes in the leather carving, the operator needs to adjust the position of the alignment module 3. Using a hole-opening rod 10 with a specific hole diameter, it needs to be aligned with the through hole 33 on the alignment module 3 with the corresponding hole diameter to realize the drilling operation of the leather carving. The specific operation is as follows: first, rotate to loosen the locking bolt 35 so that the bottom end of the locking bolt 35 is separated from the guide strip 32, then pull the sliding plate 31 so that the sliding plate 31 slides inside the guide groove 22. After the position of the through hole 33 is aligned with the vertical position of the hole-opening rod 10, rotate the locking bolt 35 so that the bottom end of the locking bolt 35 and the guide strip 32 abut against each other, thereby locking the position of the sliding plate 31. Finally, when drilling holes in the leather carving, the operator activates the impact cylinder 6, which causes the lifting column 61 to descend rapidly. The lifting column 61 then drives the drilling rod 10 to descend synchronously, and the punch 103 below the drilling rod 10 is used to drill holes in the leather carving.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
