Description

Technical Field

[0001] This utility model relates to the field of anchor drilling machine processing technology, and in particular to a clamping device for anchor drilling machines. Background Technology

[0002] In mining, tunneling, and other engineering projects, rock bolt support is a core technology for ensuring rock mass stability, and its quality directly depends on the machining precision of the rock bolt itself. The rock bolt itself, as a slender rod-shaped component with a very high length-to-diameter ratio, is usually made of materials such as threaded steel. Before final assembly, it requires a series of precision machining processes, including thread turning, heat treatment, and spraying an anti-corrosion coating.

[0003] In the machining process of anchor bolts for anchor drilling rigs, clamping slender rod-shaped workpieces is a fundamental step in ensuring the accuracy of processes such as thread machining. When clamping the workpiece, the operator must frequently and repeatedly turn the screw manually to drive the jaws. This reliance on manual screw tightening for positioning is difficult to control precisely and consistently over multiple operations, potentially leading to insufficient clamping force causing the workpiece to loosen during machining, or excessive clamping damaging the workpiece surface and precision threads. Therefore, there is an urgent need for a clamping device that facilitates the positioning of anchor bolts for anchor drilling rigs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping device for anchor drilling rigs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A clamping device for an anchor drilling rig includes a base, a lower clamping seat fixedly disposed on the top of the base, an upper clamping seat vertically movably disposed above the lower clamping seat, and a lower side plate and an upper side plate fixedly disposed on both sides of the lower clamping seat and the upper clamping seat, respectively; a fixing frame is fixedly disposed on the base, and locking members are movably disposed on both sides of the fixing frame, and the locking members have locking cavities adapted to the corresponding lower side plate and upper side plate.

[0006] In addition, a preferred structure is that both sides of the lower clamp are provided with fixing plates facing outward, and the other end of each fixing plate is connected to a fixing frame.

[0007] In addition, a preferred structure is that each of the fixing plates is provided with a sliding groove, and the bottom of each locking member is provided with a slider that matches the sliding groove.

[0008] In addition, a preferred structure is that multiple guide posts are fixed vertically upward on the top of the upper clamp, and all the guide posts pass through the fixing frame.

[0009] Furthermore, in a preferred configuration, a lower magnetic component is fixedly disposed on the top of the upper clamp, and an upper magnetic component that is compatible with and repulses the lower magnetic component is fixedly disposed on the fixing frame.

[0010] In addition, in a preferred structure, a pull plate is fixedly provided on the top of each locking member, and a bolt is rotatably provided on the pull plate through a bearing. The two ends of the bolt are respectively provided with a threaded part and a knob. Fixing blocks are provided on both sides of the upper clamp, and each fixing block is provided with a threaded groove that matches the threaded part.

[0011] The beneficial effects of this utility model are as follows: by quickly engaging the locking component with the lower and upper side plates, and locking it with the engagement of the bolt and the screw groove, the upper and lower clamping seats are quickly closed and fixed, replacing the traditional operation of frequently rotating the lead screw, improving clamping efficiency, and avoiding inconsistencies in manual operation force while providing sufficient clamping force. This can effectively prevent damage to the workpiece surface and ensure processing accuracy and safety. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5A clamping device for an anchor drilling rig includes a base 1. A lower clamping seat 2 is fixedly mounted on the top of the base 1, and an upper clamping seat 3 is vertically movably mounted above the lower clamping seat 2. A lower side plate 21 and an upper side plate 31 are fixedly mounted on the sides of the lower clamping seat 2 and the upper clamping seat 3, respectively. A fixing frame 11 is fixedly mounted on the base 1. Locking members 4 are movably mounted on both sides of the fixing frame 11, and the locking members 4 have locking cavities 41 that are adapted to the corresponding lower side plate 21 and upper side plate 31.

[0016] The lower clamp 2 has a fixing plate 22 on both sides facing outward, and the other end of the fixing plate 22 is connected to the fixing frame 11.

[0017] Each of the fixed plates 22 has a sliding groove 221, and the bottom of each locking member 4 is provided with a slider that matches the sliding groove 221. Through the matching arrangement between the slider and the sliding groove 221, smooth movement of the locking member 4 can be achieved. This is prior art and will not be described in detail.

[0018] The upper clamp 3 has multiple guide posts 33 fixed vertically upward on its top, and all guide posts 33 pass through the fixing frame 11. The guide posts 33 provide vertical guidance for the upper clamp 3, thereby improving the stability of the upper clamp 3 during movement.

[0019] The upper clamp 3 has a lower magnetic component 34 fixedly mounted on its top, and an upper magnetic component 12 that is compatible with and repulsors the lower magnetic component 34 is fixedly mounted on the fixing frame 11. Through the compatible and repulsive magnetic force between the lower magnetic component 34 and the upper magnetic component 12, the upper clamp 3 can be pushed downwards, and with the weight of the upper clamp 3 itself, the workpiece can be clamped more effectively.

[0020] Among them, the top of the locking component 4 is fixedly provided with a pull plate 42, and the pull plate 42 is rotatably provided with a bolt 43 through the installation bearing. The two ends of the bolt 43 are respectively provided with a threaded part 431 and a knob 432. The upper clamp 3 is provided with a fixing block 32 on both sides, and the fixing block 32 is provided with a threaded groove 321 that matches the threaded part 431.

[0021] In this embodiment, silicone pads are provided on the inner walls of both the lower clamp 2 and the upper clamp 3. By clamping the lower clamp 2 and the upper clamp 3 to the outside of the workpiece, the workpiece can be positioned. This is existing technology, so it will not be described in detail.

[0022] Furthermore, when the user needs to clamp the workpiece, simply place the workpiece between the lower clamp 2 and the upper clamp 3. At this time, the lower side plate 21 and the upper side plate 31 are tightly pressed together. Then, simply push the locking members 4 on both sides towards the center to lock the lower side plate 21 and the upper side plate 31 into the locking cavity 41. In this way, the lower side plate 21 and the upper side plate 31 can be fixed through the locking cavity 41, thereby achieving fixed clamping between the lower clamp 2 and the upper clamp 3.

[0023] Finally, simply rotate the bolt 43 by knob 432 to engage the threaded part 431 on the bolt 43 into the threaded groove 321, thereby fixing the locking part 4 and thus fixing and clamping the workpiece.

[0024] Furthermore, when the user needs to release the workpiece clamping, simply rotate the knobs 432 on both sides to release the engagement between the threaded portion 431 and the threaded groove 321. Then, simply pull the locking members 4 on both sides outward to release the locking cavity 41 from fixing the lower side plate 21 and the upper side plate 31. Finally, simply lift the upper clamp 3 upward to directly remove the workpiece.

[0025] Furthermore, the magnetic force between the upper magnetic component 12 and the lower magnetic component 34, combined with the gravity of the upper clamp 3, can achieve initial positioning of the workpiece. With the engagement and locking between the threaded part 431 and the threaded groove 321, further positioning of the workpiece can be achieved to ensure the positioning effect of the workpiece.

[0026] In this invention, the locking member 4 engages quickly with the lower side plate 21 and the upper side plate 31, and the bolt 43 engages with the screw groove 321 to lock, thereby achieving rapid closure and fixation of the upper clamping seat 3 and the lower clamping seat 2. This replaces the traditional operation of frequently rotating the lead screw, improves clamping efficiency, provides sufficient clamping force while avoiding inconsistencies in manual operation force, effectively prevents damage to the workpiece surface, and ensures processing accuracy and safety.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
