Description

Technical Field

[0001] The utility model relates to the technical field of drill wear-resistant plate processing, and specifically relates to a drill fixture for drill wear-resistant plates. Background Technique

[0002] A drill wear-resistant plate is a high-strength wear-resistant steel plate with high anti-wear ability and good impact performance. It is mainly used for key components of drills, such as bucket plates, side cutting edges, bucket bottom plates, blades, etc. These components require materials that are particularly tough and have extremely high wear resistance. The drill wear-resistant plate can significantly improve the service life of the drill, reduce the frequency of maintenance and replacement, and thus reduce operating costs.

[0003] For example, a fixture for facilitating the disassembly of a wear-resistant plate provided by a Chinese utility model patent with the publication number CN220179166U. In this utility model, the rotation of multiple screws can drive the up and down movement of two L-shaped plates, thereby installing and fixing the wear-resistant plate body. The two L-shaped plates can be limited on multiple screws through multiple limit blocks. The multiple screws can be rotated simultaneously through a transmission mechanism. The multiple screws can be rotated simultaneously through two worm gears, multiple worm wheels, multiple limit plates, transmission rods, two driving bevel gears, and two driven bevel gears. The electric wrench can drive the worm gear to rotate through a circular block and a hexagonal groove. The two worm gears can be limited through multiple support plates. The stability of the wear-resistant plate body after being clamped and fixed can be improved through two corrugated anti-slip plates. Multiple mounting plates can be installed through multiple rectangular grooves. The installation of this fixture can be facilitated through multiple mounting plates, multiple bolts, and mounting holes.

[0004] During the processing of drill wear-resistant plates, in order to ensure the processing effect of drill wear-resistant plates, a drill fixture is required to position and clamp the drill wear-resistant plates. However, in the prior art, most drill fixtures can only position and clamp drill wear-resistant plates with regular shapes. For drill wear-resistant plates with irregular shapes, the drill fixture cannot well position and clamp them, resulting in poor stability during the processing process, thus affecting the processing effect of drill wear-resistant plates. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drill fixture for drill wear-resistant plates to solve the problem of poor clamping stability proposed in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A drilling rig clamp for a wear-resistant plate of a drilling rig, comprising a drilling rig clamp body, a clamping assembly, a limiting assembly and a sliding assembly; the drilling rig clamp body includes a U-shaped base and a fixed pressing plate for pressing against the wear-resistant plate of the drilling rig; the fixed pressing plate is connected to the U-shaped base by bolts; the clamping assembly is arranged on the U-shaped base; the clamping assembly includes a screw rod, a movable plate, a receiving groove, a transmission groove, a wedge-shaped block and a pressing block for clamping the wear-resistant plate of the drilling rig; the screw rod is inserted through the U-shaped base and is threadedly connected to the U-shaped base; the movable plate is connected to the end of the screw rod through the limiting assembly; a receiving groove is formed in the movable plate; two transmission grooves are symmetrically formed in the receiving groove; the wedge-shaped block is slidably arranged in the receiving groove; the pressing block is slidably arranged in the transmission groove through the sliding assembly, and the end of the pressing block extends to the outside through the transmission groove; the pressing block is in contact with the surface of the wear-resistant plate of the drilling rig.

[0007] Preferably, the movable plate is slidably matched with the U-shaped base.

[0008] Preferably, both sides of one end of the wedge-shaped block close to the fixed pressing plate are provided with inclined surface A.

[0009] Preferably, one end of the pressing block away from the fixed pressing plate is provided with inclined surface B, and the inclined surface B is in sliding contact with the inclined surface A.

[0011] Preferably, more than half of the volume of the ball head end of the ball head connecting rod is located in the limiting groove.

[0012] Preferably, the sliding assembly includes a sliding groove and a sliding block; at least one sliding groove is formed in the transmission groove; at least one sliding block is fixedly arranged on the pressing block; the sliding block is slidably matched with the sliding groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. By setting up the clamping assembly, during use, first place the drill rig wear-resistant plate on the U-shaped base, and position the drill rig wear-resistant plate between the fixed abutment plate and the movable plate. Then, rotate the rotating handle on the screw to make the screw rotate, thread the screw with the U-shaped base, and make the movable plate slide on the U-shaped base towards the fixed abutment plate through the limiting assembly. When one of the pressing blocks contacts the surface of the drill rig wear-resistant plate, at this time, the pressing block will slide in the transmission groove through the sliding assembly, causing the inclined surface B on the pressing block to squeeze the inclined surface A on the wedge block, making the wedge block slide in the receiving groove, and the other inclined surface A on the wedge block to squeeze the inclined surface B on the other pressing block, causing the other pressing block to slide in the other transmission groove through the sliding assembly, so that the two pressing blocks can automatically align and contact the drill rig wear-resistant plate through the wedge block until the other pressing block contacts the surface of the drill rig wear-resistant plate. At this time, the positioning and clamping of the drill rig wear-resistant plate are completed, and the drill rig wear-resistant plate can be processed. Compared with the prior art, the structure of the present utility model is simple and ingeniously designed, and can position and clamp the drill rig wear-resistant plate with an irregular shape, with relatively high stability.

By setting up the limiting groove and the ball head connecting rod, using the rotational cooperation between the ball head connecting rod and the limiting groove, and setting more than half of the volume of the ball head end of the ball head connecting rod to be located within the limiting groove, when the screw rotates, the ball head connecting rod will rotate within the limiting groove, enabling the movable plate to slide on the U-shaped base towards or away from the fixed abutment plate, so as to realize the positioning and clamping or loosening of the drill rig wear-resistant plate with an irregular shape.

[0016] 3. By setting up the sliding groove and the sliding block, when the pressing block slides in the transmission groove, the sliding block will slide in the sliding groove, and the sliding block and the sliding groove can limit the position of the pressing block to prevent the pressing block from disengaging from the sliding of the transmission groove, thereby affecting the normal use of the present utility model.

[0027] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a drill clamp for a drill wear-resistant plate, including a drill clamp body 1, a clamping assembly 2, a limiting assembly 3 and a sliding assembly 4; the drill clamp body 1 includes a U-shaped base 101 and a fixed pressing plate 102 for pressing against the drill wear-resistant plate; the fixed pressing plate 102 is connected to the U-shaped base 101 by bolts; the clamping assembly 2 is arranged on the U-shaped base 101;

[0028] The clamping assembly 2 includes a screw 201, a movable plate 202, a receiving groove 203, a transmission groove 204, a wedge block 205 and a pressing block 206 for clamping the drill wear-resistant plate; the screw 201 passes through the U-shaped base 101 and is threadedly connected to the U-shaped base 101; the movable plate 202 is connected to the end of the screw 201 through the limiting assembly 3; the movable plate 202 is slidably matched with the U-shaped base 101; a receiving groove 203 is opened in the movable plate 202; two transmission grooves 204 are symmetrically opened in the receiving groove 203; the wedge block 205 is slidably arranged in the receiving groove 203; the pressing block 206 is slidably arranged in the transmission groove 204 through the sliding assembly 4, and the end of the pressing block 206 passes through the transmission groove 204 and extends to the outside; the pressing block 206 is in contact with the surface of the drill wear-resistant plate; both sides of one end of the wedge block 205 close to the fixed pressing plate 102 are set as inclined surface A; one end of the pressing block 206 far from the fixed pressing plate 102 is set as inclined surface B, and the inclined surface B is in sliding contact with the inclined surface A.

[0029] The utility model is provided with a clamping assembly 2. When in use, first, place the drill rig wear-resistant plate on the U-shaped base 101, and make the drill rig wear-resistant plate located between the fixed pressing plate 102 and the movable plate 202. Then, rotate the rotating handle on the screw rod 201 to make the screw rod 201 rotate, thread the screw rod 201 with the U-shaped base 101, and make the movable plate 202 slide on the U-shaped base 101 towards the direction close to the fixed pressing plate 102 through the limiting assembly 3. When one of the pressing blocks 206 contacts the surface of the drill rig wear-resistant plate, at this time, the pressing block 206 will slide in the transmission groove 204 through the sliding assembly 4, so that the inclined surface B on the pressing block 206 presses the inclined surface A on the wedge block 205, making the wedge block 205 slide in the receiving groove 203, and the other inclined surface A on the wedge block 205 presses the inclined surface B on the other pressing block 206, making the other pressing block 206 slide in the other transmission groove 204 through the sliding assembly 4, so that the two pressing blocks 206 can automatically correct the contact with the drill rig wear-resistant plate through the wedge block 205 until the other pressing block 206 contacts the surface of the drill rig wear-resistant plate.

Compared with the prior art, the utility model has a simple structure and ingenious design, can position and clamp the drill rig wear-resistant plate with an irregular shape, and has high stability.

[0030] As a preferred implementation, the limiting assembly 3 includes a limiting groove 301 and a ball head connecting rod 302; a limiting groove 301 is opened on one side of the movable plate 202 close to the screw rod 201; the ball head connecting rod 302 is fixedly arranged on one side of the screw rod 201 close to the movable plate 202; the ball head connecting rod 302 is rotationally matched with the limiting groove 301; more than half of the volume of the ball head end of the ball head connecting rod 302 is located in the limiting groove 301.

[0031] The utility model is provided with the limiting groove 301 and the ball head connecting rod 302. By using the rotational matching of the ball head connecting rod 302 and the limiting groove 301, and setting more than half of the volume of the ball head end of the ball head connecting rod 302 to be located in the limiting groove 301, when the screw rod 201 rotates, the ball head connecting rod 302 will rotate in the limiting groove 301, so that the movable plate 202 can slide on the U-shaped base 101 towards the direction close to or away from the fixed pressing plate 102, so as to realize the positioning and clamping or loosening of the drill rig wear-resistant plate with an irregular shape.

[0032] As a preferred implementation, the sliding assembly 4 includes a sliding groove 401 and a sliding block 402; two sliding grooves 401 are symmetrically opened on both sides of the inner wall of the transmission groove 204; two sliding blocks 402 are symmetrically fixedly arranged on both sides of the pressing block 206; the sliding block 402 is slidably matched with the sliding groove 401.

[0033] By providing a sliding groove 401 and a sliding block 402, when the pressing block 206 slides within the transmission groove 204, the sliding block 402 will slide within the sliding groove 401. The sliding block 402 and the sliding groove 401 can restrict the position of the pressing block 206, preventing the pressing block 206 from disengaging from the sliding within the transmission groove 204, thereby affecting the normal use of the present utility model.

[0034] Working principle: During use, first, place the drill rig wear-resistant plate on the U-shaped base 101 and position the drill rig wear-resistant plate between the fixed pressing plate 102 and the movable plate 202. Then, rotate the rotating handle on the screw rod 201 to rotate the screw rod 201. Since the screw rod 201 is threadedly connected to the U-shaped base 101, the ball head connecting rod 302 rotates within the limiting groove 301, causing the movable plate 202 to slide on the U-shaped base 101 towards the fixed pressing plate 102. When one of the pressing blocks 206 comes into contact with the surface of the drill rig wear-resistant plate, at this time, the pressing block 206 slides within the transmission groove 204, causing the sliding block 402 to slide within the sliding groove 401. The inclined surface B on the pressing block 206 presses against the inclined surface A on the wedge-shaped block 205, causing the wedge-shaped block 205 to slide within the receiving groove 203. The other inclined surface A on the wedge-shaped block 205 presses against the inclined surface B on the other pressing block 206, causing the other pressing block 206 to slide within the other transmission groove 204 and the sliding block 402 to slide within the sliding groove 401. In this way, the two pressing blocks 206 can automatically align and come into contact with the drill rig wear-resistant plate through the wedge-shaped block 205 until the other pressing block 206 comes into contact with the surface of the drill rig wear-resistant plate. At this point, the positioning and clamping of the drill rig wear-resistant plate are completed, and the drill rig wear-resistant plate can then be processed.

[0035] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
