Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber stopper punching technology, and in particular to a rubber stopper punching device. Background Technology
[0002] Rubber stoppers are generally solid rubber stoppers during the production process. However, depending on the scope and field of use, such as laboratory use, it is often necessary to drill holes in the rubber stoppers to connect to pipes or other equipment. Most existing rubber stopper drilling devices can only drill holes in a single or a small number of rubber stoppers at a time. When dealing with multiple rubber stoppers of different models that require drilling holes of different specifications, the drilling efficiency is relatively low and the operation is extremely inconvenient. Therefore, we have proposed a rubber stopper drilling device. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0019] like Figure 1-4 As shown, this utility model is a rubber stopper punching device, including a base 1. The device is characterized by: side pillars 3 installed on both the left and right sides of the upper end of the base 1; a top plate 2 fixed to the top of each side pillar 3; a side sliding groove 31 opened inside the side pillar 3; a sliding rod 32 installed inside the side sliding groove 31; a cylinder 4 installed on the top plate 2; a push rod 41 fixed to the output end of the bottom of the cylinder 4; a pressure block 42 fixedly sleeved at the bottom of the push rod 41; the pressure block 42 is movably sleeved on both sides of the sliding rod 32; the sliding rod 32 and the push rod 41 are arranged parallel to each other, and the push rod 41 passes through the top of the base 1. The sliding rod 32 serves as a guide and limiter, ensuring the stability of both sides when the pressure block 42 is pressed down. The cylinder 4 is a servo cylinder, connected to an external power supply and control panel via wires. Starting the cylinder 4 extends the push rod 41, thereby causing the pressure block 42 to press down along the sliding rod 32.
[0020] The base 1 has slots 11 on both the left and right sides of its upper surface. A rubber stopper positioning mechanism 5 is movably inserted into the slots 11. The rubber stopper positioning mechanism 5 includes an upper positioning block 51 and a lower positioning block 52. The upper positioning block 51 and the lower positioning block 52 can be configured with different combinations according to the size of the rubber stopper and the required hole diameter. The upper positioning block 51 has a drilling pin insertion hole 511, and a first retaining ring 513 is provided at the bottom of the upper positioning block 51. The first retaining ring 513 is located outside the drilling pin insertion hole 511 and is used to limit the position of the top of the rubber stopper. The upper positioning block 51 has positioning posts 512 at each of the four corners of its bottom end. The lower positioning block 52 has a... The lower positioning block 52 has a retaining rail 524 on its left and right sides, and a positioning insertion hole 523 is provided at each of the four corners of the top of the lower positioning block 52. The upper surface of the lower positioning block 52 has a second retaining ring 521 and a rubber plug insertion hole 522. The rubber plug insertion hole 522 is a frustum shape with a larger top and a smaller bottom. The depth of the rubber plug insertion hole 522 is greater than the height of the rubber plug, so that the bottom of the rubber plug can be completely inserted into the rubber plug insertion hole 522. The outer diameter of the upper part of the rubber plug will be slightly larger than the inner diameter of the top of the rubber plug insertion hole 522, so that when the rubber plug is inserted into the rubber plug insertion hole 522, the top can be exposed and locked into the second retaining ring 521. The rubber plug positioning mechanism 5 is movably connected to the slot 11 of the base 1 through the retaining rail 524 at the bottom. The number of the punch pin insertion holes 511, the first retaining ring 513, the second retaining ring 521, and the rubber plug insertion holes 522 are equal and not less than three, arranged in a rectangular array. The positions of the punch pin insertion holes 511, the first retaining ring 513, the second retaining ring 521, and the rubber plug insertion holes 522 correspond one-to-one. The first retaining ring 513 and the second retaining ring 521 are the same in shape and size, and the inner diameter of the first retaining ring 513 and the second retaining ring 521 is larger than the inner diameter of the punch pin insertion holes 511 and the rubber plug insertion holes 522. The first retaining ring 513 and the second retaining ring 521 are used to limit the outer ring of the top of the rubber plug. The positions of the punch pin insertion holes 511 and the rubber plug insertion holes 522 correspond to each other, ensuring that there is a rubber plug insertion hole 522 directly below each punch pin insertion hole 511. This allows for the simultaneous punching of multiple rubber plugs, greatly improving the punching efficiency.
[0021] A punch 6 is inserted into the punch 511. The punch 6 includes a nail plate 61 and a nail tube 62. The nail tube 62 is welded to the bottom end of the nail plate 61, and the two are connected in the middle. The nail plate 61 has long side wings at both ends, which increases the force-bearing area and reduces the contact pressure between the punch 6 and the pressure block 42, thereby reducing the wear rate caused by the pressure block 42. The punch 6 can be made in different models. By replacing different models of punch 6, the punching requirements of different hole diameters can be met. Replacing and installing the punch 6 is very convenient. It can be done simply by inserting and removing the punch.
[0022] Working principle: First, place the rubber stopper that needs to be drilled into the rubber stopper insertion hole 522. Then, press the upper positioning block 51 onto the lower positioning block 52 to ensure that the positioning pin 512 is inserted into the positioning insertion hole 523. Then, insert the drilling nail 6 into the drilling nail insertion hole 511 so that the bottom end of the nail tube 62 is located at the top of the rubber stopper. At this time, start the cylinder 4 to drive the push rod 41 to extend and press down the pressure block 42. The pressure block 42 can press down the nail plate 61, thereby completing the drilling work of the rubber stopper by pressing the nail tube 62 into the rubber stopper.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
