DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-4 This application is described in further detail.

[0018] The embodiment of the present application discloses a quick-changing device for a leather punching mold, comprising a base 1, a support column 2 being fixedly connected to the upper surface of the base 1, a ring plate 6 being connected to the surface of the support column 2 by means of a rotating mechanism, a plurality of groups of slide grooves 8 being provided on the surface of the ring plate 6, a slide rod 10 being fitted inside the slide grooves 8, one end of the slide rod 10 being located outside the ring plate 6 and being provided with a punch head 12, a spring 11 being connected to the other end of the slide rod 10, and the spring 11 being sleeved on the surface of the slide rod 10, one end of the spring 11 being fixedly connected to the ring plate 6, an electric push rod 9 being also fixedly connected to the surface of the support column 2, the extension and retraction directions of the electric push rod 9 and the slide rod 10 being radially arranged along the ring plate 6.

[0019] Furthermore, the rotating mechanism includes a motor 3, a gear 4, a ring gear 5 and an annular slide 7. The annular slide 7 is installed on one side of the annular plate 6 and is coaxially arranged therewith. The ring gear 5 is fixedly sleeved on the outer surface of the annular slide 7. The motor 3 is fixedly installed on the top of the support column 2. The gear 4 is fixedly installed on the power end of the motor 3, and the gear 4 is meshed with the ring gear 5.

[0020] In this embodiment, the hole type of the punch head 12 is set according to the actual commonly used hole type. By setting a rotating mechanism, the annular plate 6, the slide rod 10, and the punch head 12 can be driven to rotate, and then the position of the punch head 12 can be switched to achieve the switching of punch heads 12 with different hole types. When in use, there is no need to disassemble the punch head 12. Instead, the punch head 12 can be replaced by setting a rotating mechanism and coordinating with multiple groups of punch heads 12 and other mechanisms. The replacement is convenient and quick, and it is easy to use.

[0021] Specifically, by driving the motor 3 to rotate, the gear 4, the gear ring 5, the annular slide 7, the annular plate 6 and other structures are driven to rotate, wherein the motor 3 can be used in conjunction with a controller, the controller can control when the motor 3 rotates and the rotation angle, the controller can select a single-chip microcomputer as a control, the single-chip microcomputer is composed of an arithmetic unit, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption. In this embodiment, the model of the single-chip microcomputer is not required.

[0022] Furthermore, the telescopic end of the electric push rod 9 is fixedly connected to a slider 13 , and a plurality of guide grooves 14 are provided on the inner surface of the annular plate 6 . The guide grooves 14 are arranged one-to-one with the slide bars 10 , and the slider 13 can be moved into or out of the guide grooves 14 .

[0023] Furthermore, a plurality of groups of slide grooves 8 and slide rods 10 are distributed in an annular array based on the annular plate 6 .

[0024] In this embodiment, after the appropriate punching head 12 is transferred to the punching position by using the rotating mechanism, the leather to be punched is placed on the base 1, the electric push rod 9 is driven to extend, and the electric push rod 9 impacts the sliding rod 10, so that the sliding rod 10 and the punching head 12 move along the slide groove 8, and the punching head 12 can punch holes in the leather. When the electric push rod 9 drives the sliding rod 10 to move, the spring 11 is compressed. When the electric push rod 9 contracts, the compressed spring 11 extends, which can drive the sliding rod 10 and the punching head 12 to move back, so that the leather on the base 1 can be removed.

[0025] Furthermore, the punch head 12 can be detachably mounted on one end of the slide rod 10, a threaded connector is fixedly mounted on the surface of the punch head 12, and a threaded sleeve is cooperatively mounted on one end of the slide rod 10. The threaded connector can be screwed into the interior of the threaded sleeve. The punch head 12 is prone to damage after long-term use. In this embodiment, when the punch head 12 is damaged, the punch head 12 can be unscrewed from the slide rod 10 and replaced with a new one.
