[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0031] See also Figure 1-Figure 3 The present embodiment provides a radial positioning device, which includes a base 100, a radial block 200 and a fine-tuning assembly 300; the radial block 200 and the base 100 slide in radial cooperation, the fine-tuning assembly 300 includes a top screw 310 and a tightening screw 320, one of the radial block 200 and the base 100 is threadedly cooperated with the top screw 310, and the other is abutted against the end of the top screw 310; the radial block 200 and the base 100 are locked by the tightening screw 320; the top screw 310 and the tightening screw 320 are both arranged radially, and the pulling force of the tightening screw 320 on the radial block 200 is opposite to the thrust of the top screw 310 on the radial block 200.
[0032] The radial positioning device provided in this embodiment changes the traditional single-body radial block into two separate structures of the base 100 and the radial block 200. Figure 1 The radial block 200 and the base 100 are slidably matched, and the tension of the tightening screw 320 on the radial block 200 is opposite to the thrust of the top screw 310 on the radial block 200. Therefore, under the dual action of the tightening screw 320 and the top screw 310 in the fine-tuning assembly 300, the radial block 200 can remain relatively fixed with the base 100. When it is necessary to fine-tune the radial position of the radial block 200, the top screw 310 and the tightening screw 320 can be screwed to make the radial block 200 slide radially relative to the base 100. In this way, the radial position of the radial block 200 can be fine-tuned through the fine-tuning assembly 300, which is beneficial to improving the radial positioning accuracy.
[0033] Preferably, a main body 210 and a blade 220 may be provided in the specific structure of the radial block 200, the main body 210 is mounted on the base 100, the blade 220 is mounted on the main body 210 in a detachable connection manner, and the blade 220 is used to contact the workpiece, that is, during use, the main body 210 of the radial block 200 will not be worn, only the blade 220 will be worn to be uneven, so that when the blade 220 is worn and the precision is insufficient, the worn blade 220 can be directly removed from the main body 210, And install a new blade 220 on the main body 210, without the need to assemble and level the entire radial block 200; it should be noted that the traditional single-body radial block is an integrated alloy structure. Once the contact surface between the single-body radial block and the workpiece is insufficiently accurate due to wear, the single-body radial block needs to be assembled and leveled, and the single-body radial block needs to be scrapped after being assembled twice, which causes great waste. In this embodiment, only the blade 220 of the radial block 200 needs to be replaced separately, which can reduce waste and reduce costs.
[0034] Furthermore, the structural strength of the blade 220 can be set to be better than the structural strength of the main body 210, so that the wear resistance of the blade 220 can be improved, the service life of the blade 220 can be extended, and the cost can be reduced.
[0035] Specifically, cemented carbide can be used as the material of the blade 220. Cemented carbide is an alloy material made of a hard compound of a refractory metal and a bonding metal through a powder metallurgy process. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500° C., and it still has a high hardness at 1000° C. Therefore, using cemented carbide to manufacture the blade 220 can effectively extend the service life of the blade 220. For example, powder metallurgy high-speed steel can be selected as the material of the blade 220.
[0036] Preferably, a mounting groove 212 may be provided on the main body 210 , and the blade 220 may be installed in the mounting groove 212 , so that the mounting groove 212 may be used to position the blade 220 , thereby improving the assembly reliability of the blade 220 and the main body 210 .
[0037] Specifically, the back side of the blade 220 can be pressed against the bottom of the mounting groove 212, and the side wall of the blade 220 can be gap-matched with the groove wall of the mounting groove 212, so that the blade 220 is stuck in the mounting groove 212. In this way, the groove bottom and groove wall of the mounting groove 212 can both limit the blade 220.
[0038] The blade 220 of the radial block 200 can be connected to the main body 210 via a locking screw 230 , which can not only meet the detachable requirements of the blade 220 and the main body 210 , but also ensure the connection reliability of the blade 220 and the main body 210 after assembly.
[0039] Specifically, a second countersunk hole 214 can be opened on the front side of the blade 220, and a third threaded hole can be opened at the bottom of the main body 210 corresponding to the mounting groove 212. During assembly, the locking screw 230 is passed through the second countersunk hole 214 and then screwed into the third threaded hole. After the locking screw 230 is tightened, the head can sink into the second countersunk hole 214 and be blocked by the step surface of the second countersunk hole 214, thereby achieving a fixed connection between the blade 220 and the main body 210, and the head of the locking screw 230 can be hidden in the second countersunk hole 214.
[0040] The fixing screw 400 can be used to connect the base 100, the radial block 200 and the pull rod 500. Specifically, a waist-shaped hole 211 can be opened on the radial block 200, and the length direction of the waist-shaped hole 211 is set to be consistent with the radial direction; a positioning hole arranged opposite to the waist-shaped hole 211 is opened on the base 100. During assembly, the tail end of the fixing screw 400 can be passed through the waist-shaped hole 211 on the radial block 200 and the positioning hole on the base 100 in turn, and then threadedly matched with the pull rod 500. After tightening the fixing screw 400, the head end of the fixing screw 400 can press the radial block 200. In this way, the connection between the base 100, the radial block 200 and the pull rod 500 can be achieved. Because the length direction of the waist-shaped hole 211 is consistent with the radial direction, the radial block 200 can slide radially relative to the base 100, which can meet the needs of the fine-tuning component 300 to fine-tune the radial block 200. Specifically, the waist-shaped hole 211 , the positioning hole and the fixing screw 400 can be set to two, and correspond one to one.
[0041] The above-mentioned base 100 may specifically include a bearing portion and a first fine-adjustment portion, and the above-mentioned radial block 200 may specifically include a mounting portion and a second fine-adjustment portion. The bearing portion of the base 100 and the mounting portion of the radial block 200 may be radially slidably matched, and the second fine-adjustment portion and the first fine-adjustment portion are arranged opposite to each other. A first threaded hole extending radially is opened on the first fine-adjustment portion, and the top screw 310 is matched with the first threaded hole, and the top screw 310 is abutted against the radial block 200. In this way, the fine-adjustment function of the radial block 200 can be realized by twisting the top screw 310.
[0042] A first countersunk hole extending radially can also be opened on the first fine-tuning part of the base 100, and a second threaded hole 213 can be opened on the second fine-tuning part of the radial block 200. During assembly, the tail end of the tightening screw 320 can be passed through the first countersunk hole of the first fine-tuning part and screwed into the second threaded hole 213 of the second fine-tuning part. After tightening the tightening screw 320, the head end of the tightening screw 320 can press the first fine-tuning part, so that the fine-tuning function of the radial block 200 can be realized by screwing the tightening screw 320.
[0043] Specifically, a sliding groove may be provided on the radial block 200 , and the sliding groove is slidably matched with the base 100 , so that the sliding match between the radial block 200 and the base 100 can be achieved.
[0044] In fact, the base 100 and the radial block 200 are both substantially L-shaped, and the radial block 200 is installed in the upper L-shaped groove of the base 100 .
[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
