Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cup technology, specifically a porous vacuum suction cup. Background Technology

[0002] Vacuum chucks, as key components in industrial automation, are widely used in machining, electronics manufacturing, and logistics handling to achieve precise positioning and fixation of workpieces by adsorbing them. Among them, porous vacuum chucks, with their advantages of high adsorption force and uniform pressure distribution, are particularly suitable for machining precision workpieces requiring high surface flatness. During workpiece machining, impurities such as cutting fluid and metal shavings can easily enter the internal channels through the pores on the chuck surface, leading to decreased adsorption performance or even equipment malfunction. Therefore, current technologies typically require operators to clean the chucks during machining breaks or after machine shutdown.

[0003] In the existing multi-hole vacuum suction cup, the pores are rinsed with water during cleaning, and then the surface cutting fluid is discharged by sliding the switch back and forth. The above operation is repeated to clean the remaining areas. Since the switches of multiple areas need to be operated one by one, the repeated push and pull action is time-consuming. For example, the three areas on the suction cup need to be operated independently at least 3 times, resulting in low cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-hole vacuum suction cup that connects multiple sliding cylinders through a set collar and crossbar, thus solving the problem of low cleaning efficiency when operating one by one.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a multi-hole vacuum suction cup, including a vacuum suction cup body, collars and crossbars. The outer surface of the vacuum suction cup body is provided with two sets of negative pressure switch bodies. Each set of negative pressure switch bodies has a slide cylinder. There are two collars, which are respectively sleeved on the corresponding slide cylinders. The collars have a first semi-circular ring and a second semi-circular ring. The first semi-circular ring and the second semi-circular ring are connected. Each of the two second semi-circular rings has a limit groove. The two ends of the crossbar are respectively fitted into the corresponding limit grooves.

[0007] Furthermore, an inlet groove is provided on the second semi-circular ring, which is connected to the limiting groove, and the end of the crossbar is slidably fitted in the inlet groove.

[0008] Furthermore, a locking block is installed on both sides of the first semicircular ring, and a locking groove for matching the locking block is opened on both sides of the second semicircular ring.

[0009] Furthermore, both the first and second semicircular rings have a first semicircular ring inside them, and the two first semicircular rings cooperate to form a circular hole, in which the sliding cylinder is fitted.

[0010] Furthermore, each set of negative pressure switch bodies has a cylinder, and each slide cylinder slides and fits onto the corresponding cylinder.

[0011] Furthermore, an instrument panel and a backflush valve are provided on the outer surface of the vacuum suction cup body.

[0012] This utility model has the following beneficial effects:

[0013] This utility model connects multiple sliding cylinders through a set collar and crossbar, thereby mechanically coupling multiple negative pressure switches. A single sliding operation can simultaneously control the opening and closing of all negative pressure switches in all areas, reducing the number of operations. For example, three operations for three areas on the suction cup are reduced to one, improving cleaning efficiency. Moreover, the switching operation can be completed with one hand during rinsing, freeing up the other hand to hold the spray gun and reducing operational complexity.

[0014] This invention utilizes a locking block and a locking groove to disassemble the collar. When installing the collar, the locking block is inserted into the locking groove to fix the first and second semi-circular rings, thus securing the collar to the slide cylinder. To remove the collar from the slide cylinder, the first and second semi-circular rings are moved to the sides, causing the locking block to move out of the locking groove and release the limiting position, allowing the collar to be removed from the slide cylinder. The operation is simple and the installation and disassembly are convenient, thus facilitating the installation and disassembly of the collar, improving efficiency, and increasing the practicality of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-hole vacuum suction cup, including a vacuum suction cup body 1, a collar 3, and a crossbar 5. The outer surface of the vacuum suction cup body 1 is provided with an instrument panel 101 and a backflush valve 102. The negative pressure switch body 2, instrument panel 101, and backflush valve 102 are all prior art and will not be described in detail here. The outer surface of the vacuum suction cup body 1 is provided with two sets of negative pressure switch bodies 2. Each set of negative pressure switch bodies 2 has a slide cylinder 202 and a cylinder 201. Each slide cylinder 202 is slidably fitted onto its corresponding cylinder 201. Two collars 3 are fitted onto their respective slide cylinders 202. Each collar 3 has a first semi-circular ring 301 and a second semi-circular ring 303 connected together. The second semi-circular ring 303 has an inlet groove 6 that communicates with a limiting groove 7. The end of the crossbar 5 is slidably fitted into the inlet groove 6. Both second semi-circular rings 303 have limiting grooves 7. The two ends of the crossbar 5 are... The crossbar 5 is not fitted into the corresponding limiting groove 7. The limiting groove 7 has a flange on its side to limit the crossbar 5. When cleaning the air holes of the vacuum suction cup body 1, the sliding cylinder 202 discharges the cutting fluid from the air holes of the vacuum suction cup body 1. At this time, the collar 3 is fitted onto the sliding cylinder 202, and then the two adjacent collars 3 are connected by the crossbar 5. The two ends of the crossbar 5 are slid horizontally into the guide grooves 6 of the two second semicircular rings 303 until they are at the top of the limiting groove 7. At this time, the crossbar 5 is slid vertically so that the two ends of the crossbar 5 exit from the two guide grooves 6. The crossbar 5 is limited in the limiting groove 7. At this time, a single collar 3 can be slid horizontally. The crossbar 5 drives the other collar 3 to move horizontally in sync, thereby driving the slide cylinder 202 of each group of negative pressure switch bodies 2 to slide and adjust the negative pressure. This allows for synchronous cleaning of each area on the vacuum suction cup body 1. When individual operation is required, simply slide the crossbar 5 to the top so that the crossbar 5 moves from the limiting groove 7 to the guide groove 6, and then move the crossbar 5 horizontally to remove it from the guide groove 6. This allows each negative pressure switch body 2 to operate independently.

[0023] Both sides of the first semicircular ring 301 are equipped with locking blocks 4, and both sides of the second semicircular ring 303 are provided with locking grooves 304 that mate with the locking blocks 4. Both the first and second semicircular rings 301 and 303 have first semicircular rings 301 inside them. The two first semicircular rings 301 fit together to form a circular hole, and the slide cylinder 202 fits into the circular hole. When installing the collar 3, the first semicircular ring 301 and the second semicircular ring 303 are moved simultaneously along both sides of the slide cylinder 202 towards the side closer to the slide cylinder 202, so that the first semicircular ring 301 and the second semicircular ring 303 fit together to form a circular hole. The circular hole formed by the arc grooves 302 of the two semicircular rings 303 is on the outer surface of the slide cylinder 202. At this time, the locking block 4 is inserted into the locking groove 304 to fix the first semicircular ring 301 and the second semicircular ring 303, thus fixing the collar 3 on the slide cylinder 202. When it is necessary to remove the collar 3 from the slide cylinder 202, move the first semicircular ring 301 and the second semicircular ring 303 to both sides, so that the locking block 4 moves out of the locking groove 304 to release the restriction on the first semicircular ring 301 and the second semicircular ring 303, and then the collar 3 can be removed from the slide cylinder 202.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
