Description

Technical Field

[0001] This utility model relates to the field of machine tool processing equipment technology, and in particular to an adjustable dust removal device suitable for dust generated during graphite material cutting. Background Technology

[0002] During machine tool operation, such as when cutting graphite, a large amount of dust is easily generated. If this dust is not removed in time, it will have adverse effects on the machine tool and the operator, endangering the service life of the machine tool and the health of the operator. Therefore, a certain number of dust collection ducts are usually installed in machine tool workshops to collect and remove the dust generated during machine tool processing.

[0003] In existing technologies, dust collection ducts are typically hooked onto machine tools using wire. However, this method faces challenges due to the limited hooking positions on machine tools, making hooking inconvenient. Furthermore, the vibrations experienced by machine tools during operation can cause the dust collection ducts to easily detach and require re-hooking and repositioning, thus affecting work efficiency. Utility Model Content

[0004] This application provides an adjustable dust removal device that eliminates the need to consider whether there is enough space on the machine tool to hang the dust removal duct. It allows for the placement of the dust removal duct as needed, making it convenient to use. It also reduces the impact of machine tool vibration on the dust removal duct, and the dust removal duct is less likely to fall off, thus ensuring the operator's work efficiency.

[0005] This application provides an adjustable dust removal device, including a base, a support rod, a connecting rod, and a locking ring. The support rod extends vertically and is fixedly mounted on the top of the base. The support rod has a plurality of positioning holes spaced apart in the vertical direction. The connecting rod includes a first connecting part and a second connecting part connected to each other. The first connecting part is vertically connected to the support rod through a first positioning block, and a fastening screw that mates with the positioning holes is installed on the first positioning block. The locking ring is connected to the end of the second connecting part away from the first connecting part. The locking ring has a locking port and a locking screw for connecting the locking port. When the locking ring surrounds and covers the dust removal duct, the locking port is locked by the locking screw to fix the dust removal duct inside the locking ring.

[0006] In one possible implementation, the support rod is an I-shaped steel plate, including a main body and a first guide part and a second guide part symmetrically and vertically connected to both sides of the main body, and the first guide part and the second guide part form a guide groove.

[0007] The first positioning block is a T-shaped block, including a guide block and a connecting plate, wherein the guide block cooperates with the guide groove, and after the first positioning block is installed to the support rod in place, the connecting plate abuts against the outer ends of the first guide portion and the second guide portion.

[0008] In one possible implementation, the first connecting part is an I-beam steel plate.

[0009] In one possible implementation, the second connecting part is a spiral steel pipe, and the second connecting part and the first connecting part are connected by a second positioning block. The second positioning block is embedded in the groove of the first connecting part, and the second connecting part passes through the second positioning block and the first connecting part simultaneously by means of threaded engagement. Adjusting nuts are respectively fitted at the top of the second positioning block and the bottom of the first connecting part.

[0010] In one possible implementation, the positioning hole is an oblong hole that extends vertically and is evenly distributed in the vertical direction.

[0011] In one possible implementation, the locking ring consists of two semi-circular clamps, with the locking openings located at the connection points of the two semi-circular clamps.

[0012] Beneficial effects: Compared with the prior art, the adjustable dust removal device provided in this application can fix the dust removal duct anywhere in the machine tool workshop through the cooperation of the base, support rod, connecting rod and locking ring, without having to consider whether there is enough space on the machine tool for hooking the dust removal duct, making the use of the dust removal duct more convenient. At the same time, since the dust removal duct is not fixed to the machine tool, the impact of machine tool vibration on the stability of the dust removal duct can be greatly reduced, making the dust removal duct less likely to fall off, thereby ensuring the work efficiency of the operator.

[0013] The dust removal duct can be quickly and securely locked by using a locking ring and a locking screw.

[0014] By setting multiple positioning holes vertically on the support rod, the height of the connecting rod on the support rod can be flexibly adjusted. Then, the dust removal duct can be fixed at a suitable height position by the locking ring, making it more convenient to use. In addition, the cooperation between the support rod and the first positioning block can effectively stabilize the connecting rod, which can further improve the stability of the dust removal duct.

[0015] The purpose, features, and advantages of this utility model are fully demonstrated through the following detailed description. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] refer to Figure 1 and Figure 2 This application provides an adjustable dust removal device, including a base 10, a support rod 20, a connecting rod 30 and a locking ring 40. The support rod 20 extends vertically and is fixedly disposed on the top of the base 10. The support rod 20 is provided with a plurality of positioning holes 201 at intervals in the vertical direction. These positioning holes 201 can be evenly distributed at intervals or unevenly distributed at intervals.

[0022] The connecting rod 30 includes a first connecting part 31 and a second connecting part 32 connected to each other. The first connecting part 31 is vertically connected to the support rod 20 through a first positioning block 311, and a fastening screw 312 that cooperates with the positioning hole 201 is installed on the first positioning block 311 for fixing the first positioning block 311 to the support rod 20 through the cooperation of the first positioning block 311, the positioning hole 201 and the fastening screw 312.

[0023] More specifically, the support rod 20 is an I-shaped steel plate, including a main body 21 and a first guide part 22 and a second guide part 23 symmetrically and vertically connected to both sides of the main body 21, wherein the first guide part 22 and the second guide part 23 form a guide groove; correspondingly, the first positioning block 311 is a T-shaped block, including a guide block and a connecting plate 3111, wherein the guide block cooperates with the guide groove to facilitate quick and accurate adjustment of the height position of the first positioning block 311, wherein after the first positioning block 311 is installed in place on the support rod 20, the connecting plate 3111 abuts against the outer ends of the first guide part 22 and the second guide part 23;

[0024] The locking ring 40 is connected to the end of the second connecting part 32 away from the first connecting part 31. The locking ring 40 is provided with a locking port 401 and a locking screw 41 for connecting the locking port 401. When the locking ring 40 surrounds and covers the dust removal duct 50, the locking port 401 is locked by the locking screw 41 to fix the dust removal duct 50 inside the locking ring 40.

[0025] Therefore, the adjustable dust removal device provided in this application can be used at any location in the machine tool workshop by moving the base 10 or changing the position of the base 10 in the machine tool workshop to fix the dust removal duct 50. There is no need to deliberately consider whether there is enough space on the machine tool to hook and fix the dust removal duct 50, making it more convenient to use.

[0026] Furthermore, since the support rod 20 has multiple positioning holes 201 along the vertical direction, and the connecting rod 30 cooperates with the positioning holes 201 through the first positioning block 311 and the fastening screw 312, the first positioning block 311 can be installed at different height positions of the support rod 20, thereby flexibly adjusting the height of the locking ring 40. That is, the dust removal duct 50 can be fixed at different height positions, making it more convenient to use. In the process of use, first unscrew or partially unscrew the fastening screw 312, and move the first positioning block 311 up and down based on the cooperation of the guide block and the guide groove. During the movement, the connecting plate 3111 is attached to the outer end of the first guide part 22 and the second guide part 23. After the up and down adjustment is in place, align the fastening screw 312 on the first positioning block 311 with the corresponding positioning hole 201, screw in or tighten the fastening screw 312, and lock and fix it with a nut at the other end of the fastening screw 312.

[0027] In addition, when fixing the dust removal duct 50, first open the locking port 401, then lock the locking ring 40 onto the dust removal duct 50, and then fix it with the locking screw 41. The dust removal duct 50 that matches the locking ring 40 can be fixed by the locking ring 40. Alternatively, the locking port 401 of the locking ring 40 can have a slightly larger gap, and it can be fixed by the locking screw 41 with a longer stud. This can fix dust removal ducts 50 with a slightly larger diameter, and has a wide range of applications.

[0028] In one embodiment, the first connecting part 31 is an I-shaped steel plate, which is convenient to purchase directly or to manufacture.

[0029] In one embodiment, the second connecting part 32 is a spiral steel pipe. The spiral steel pipe is formed by extruding steel coils at room temperature and then welding them using double-wire and double-sided submerged arc welding technology. This type of steel pipe is typically rolled from low-carbon steel or low-alloy structural steel strips at a certain spiral angle. It can produce large-diameter steel pipes using narrower strips. It has external threads, and because the steel plate deforms uniformly during welding, the residual stress is small, thus possessing a certain degree of elasticity. This allows the position and direction of the locking ring 40 to be adjusted to a certain extent by bending the second connecting part 32. Furthermore, after bending to the correct position, it still maintains good structural stability, i.e., the support stability for the locking ring 40. The advantage is that the locking direction of the locking ring 40 can be flexibly changed within a specific space, keeping the dust removal duct 50 in a specific extension direction to ensure the dust removal effect of the dust removal duct 50. The second connecting part 32 and the first connecting part 31 are connected by a second positioning block 321, wherein the second positioning block 321 is partially embedded in the groove of the first connecting part 31. Simultaneously, the second connecting part 32 passes through both the second positioning block 321 and the first connecting part 31 via a threaded connection. Adjusting nuts 322 are respectively fitted at the top of the second positioning block 321 and the bottom of the first connecting part 31. This allows for flexible adjustment of the height of the locking ring 40 and the dust removal duct 50 within the locking ring 40 by adjusting the height of the second connecting part 32, making it more convenient to use. When bending the second connecting part 32, bending is generally only performed at the top. At the bottom, where the second connecting part 32 mates with the second positioning block 321 and the first connecting part 31, the second connecting part 32 is straight; otherwise, it would be impossible for it to pass through the hole and be threadedly connected to the adjusting nut 322.

[0030] Under normal circumstances, the adjustment stroke of the second connecting part 32 on the first connecting part 31 is less than the adjustment stroke of the first connecting part 31 on the support rod 20. When a larger distance is needed to adjust the support height of the bracket during initial use, the height position of the connecting rod 30 on the support rod 20 can be adjusted only according to the distribution of the positioning holes 201. At this time, the height position can be finely adjusted by slightly rotating the second connecting part 32.

[0031] When a small adjustment to the height of the dust removal duct 50 is required during use, first remove the adjusting nut at the bottom of the first connecting part 31, then rotate the adjusting nut 322 at the top of the second positioning block 321 upwards, and then rotate the second connecting part 32 downwards. After rotation, first tighten the lower adjusting nut to the bottom of the first connecting part 31, and then rotate the upper adjusting nut 322 downwards to the top of the second positioning block 321 to complete the fixation of the second connecting part 32 on the first connecting part 31. To improve the connection strength between the second connecting part 32 and the first connecting part 31, one or two washers are provided between the upper adjusting nut 322 and the second positioning block 321, and these washers are fitted onto the second connecting part 32.

[0032] In one embodiment, the positioning hole 201 is an oblong hole, and the positioning hole 201 extends vertically and is evenly distributed in the vertical direction. This allows for fine adjustment of the height position of the connecting rod 30 within the stroke range of the positioning hole 201, which is equivalent to providing another means of height fine adjustment.

[0033] In one embodiment, the locking ring 40 is composed of two semi-circular clamps, and the locking port 401 is located at the connection position of the two semi-circular clamps respectively.

[0034] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
