Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to a large-size clamping device for drilling and clamping a cylinder body oil cylinder oil channel. Background Art

[0002] The clamp is the main actuator of the full hydraulic drilling rig. It is located at the front end of the drilling rig and is mainly used to remove or install the drill rod during the drilling process to prevent the drill rod and drilling tools from slipping. At present, the clamps used for drilling rigs are all horizontal cylinder clamps, which are mainly composed of cylinder body, hydraulic cylinder and claws. The hydraulic cylinders are arranged at both ends of the cylinder body, and the cylinder oil channels on the cylinder body are used to drive the cylinders. The cylinder oil channels of the clamp body are connected to the external hydraulic oil pump station. The specifications and models of the clamps vary, mainly based on the independent standards of the manufacturers. Regarding the processing of the clamp, especially the processing of the oil cylinder oil channel on the large-sized clamp cylinder, the following problems currently exist in production: the length of the large-sized clamp cylinder is slightly larger than that of the conventional clamp cylinder, which makes it impossible to cooperate with the radial drilling machine commonly used in the workshop. The main reason is that if the clamp cylinder is directly placed vertically on the base of the radial drilling machine, the radial drilling machine has limited vertical drilling space and cannot accommodate or adapt to the length of the clamp cylinder. Therefore, it is impossible to drill it in the vertical direction, resulting in the inability to complete the cylinder oil channel drilling operation well. At present, one way to solve the above problem is to purchase a larger-sized drilling machine, but the cost is high. Many companies are unwilling to purchase it for cost considerations, or use horizontal drilling operations, but the drilling accuracy is not enough and the processing quality cannot be guaranteed. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to propose a large-size clamp cylinder oil channel drilling and clamping tooling, which can be adapted to the oil channel drilling processing operations of various large-sized clamp cylinder bodies, and can be adapted to the existing conventional radial arm drilling machine, thereby solving the current problem of difficult machining of the clamp cylinder oil channel.

[0004] The technical solutions adopted by the utility model to solve the above problems are as follows:

[0005] The large-size clamp cylinder oil channel drilling clamping tool is arranged on the ground at one side of the radial drilling machine, and a sinking groove is arranged on the ground. The clamping tool comprises a fixing seat and a fastening assembly arranged on the top of the fixing seat, wherein the fixing seat is arranged in the sinking groove, and the center of the fixing seat is provided with a mounting hole for loading and fixing the clamp cylinder body; the fastening assembly comprises a positioning column, a vertical shaft and a clamping plate, the positioning column and the vertical shaft are respectively vertically fixedly arranged on the top of the fixing seat, and the vertical shaft is located in the gap between the mounting hole and the positioning column, the height of the vertical shaft is higher than the height of the positioning column, and the clamping plate is provided with a strip hole along its length direction, and the clamping plate is sleeved on the vertical shaft through the strip hole, and the vertical shaft is located at the upper side of the clamping plate. A fastening bolt for fixing the clamping plate is arranged, so that after the clamp cylinder is loaded, the clamping plate is pressed against the clamp cylinder and the positioning column, and the clamp cylinder body is pressed and fixed by the fastening bolt.

[0006] As a preferred solution of the above technical solution, the vertical shaft and the positioning column are located in the same radial direction of the mounting hole.

[0007] As a preferred solution of the above technical solution, the fixing seat is a seat body with a cylindrical structure whose shape matches the sinking groove, and a limiting ring with a flange structure abutting against the ground is arranged on the top of the fixing seat, and the fastening components are all arranged on the limiting ring.

[0008] As a preferred solution of the above technical solution, the inner diameter of the center hole of the limiting ring is consistent with the hole diameter of the mounting hole, so that the center hole of the limiting ring and the mounting hole are connected to form an integrated assembly hole, and the total depth of the assembly hole is greater than 50% of the length of the single side cylinder body of the clamp cylinder body and less than 80% of the length of the single side cylinder body of the clamp cylinder body.

[0009] As a preferred solution of the above technical solution, the thickness of the limiting ring does not exceed 90 mm.

[0010] As a preferred solution of the above technical solution, the height of the positioning column is flush with the end surface height of the single-side cylinder body after the clamp cylinder body is fixed, so that the clamping plate maintains a horizontal state to complete the pressing and fixing of the clamp cylinder body.

[0011] As a preferred solution of the above technical solution, the sinking groove is located in an area within the maximum stroke adjustment range of the radial drilling machine.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The large-size clamping tool described in the present application is completely independent of the traditional existing radial drilling machine. It is mainly arranged on one side of the drilling machine and can be used in conjunction with the radial drill as a fixed tool. It can effectively solve the problem of the limited vertical lifting stroke and limited vertical drilling operation space of the radial drilling machine itself, which makes it impossible to adapt to the processing problem of the cylinder oil channel of the long-sized clamp cylinder body. The clamping tool has a simple overall structure, low manufacturing cost, and very high practicality. It can effectively improve production efficiency and solve practical problems in practical operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] As shown in the figure, this embodiment discloses a large-size clamp cylinder oil channel drilling clamping fixture, which is arranged on the ground 2 on one side of the radial drilling machine 1, and a sinking groove 3 is arranged on the ground 2, and the sinking groove 3 is located in the area within the maximum stroke adjustment range of the radial drilling machine 1. The clamping fixture includes a fixing seat 4 and a fastening assembly arranged on the top of the fixing seat 4, wherein the fixing seat 4 is arranged in the sinking groove 3, and the center of the fixing seat 4 is provided with a mounting hole 41 for loading and fixing the clamp cylinder 9;

[0021] The fastening assembly includes a positioning column 5, a vertical shaft 6 and a clamping plate 7. The positioning column 5 and the vertical shaft 6 are respectively fixed vertically on the top of the fixing seat 4, and the vertical shaft 6 is located in the gap between the mounting hole 41 and the positioning column 5. The height of the vertical shaft 6 is higher than the height of the positioning column 5. The clamping plate 7 is provided with a strip hole 71 along its length direction. The clamping plate 7 is sleeved on the vertical shaft 6 through the strip hole 71. The vertical shaft 6 is located on the upper side of the clamping plate 7 and is provided with a fastening bolt 8 for fixing the clamping plate 7, so that after the clamping cylinder is loaded, the clamping plate 7 is pressed against the clamping cylinder and the positioning column 5, and the clamping cylinder body 9 is pressed and fixed by the fastening bolt 8.

[0022] In this embodiment, the vertical shaft 6 and the positioning column 5 are located on the same radial direction of the mounting hole 41, the fixing seat 4 is a cylindrical seat body whose shape matches the sinking groove 3, and a limiting ring 42 of a flange structure abutting against the ground 2 is provided on the top of the fixing seat 4, and the fastening components are all arranged on the limiting ring 42.

[0023] In this embodiment, the inner diameter of the center hole of the limiting ring 42 is consistent with the hole diameter of the mounting hole 41, so that the center hole of the limiting ring 42 is connected with the mounting hole 41 to form an integrated assembly hole, and the total depth of the assembly hole is greater than 50% of the single-side cylinder body length of the clamp cylinder 9 and less than 80% of the single-side cylinder body length of the clamp cylinder 9.

[0024] In this embodiment, the thickness of the limit ring 42 does not exceed 90 mm, and the height of the positioning column 5 is flush with the end surface height of the single-sided cylinder body after the clamp cylinder 9 is fixed, so that the clamping plate 7 remains horizontal to complete the pressing and fixing of the clamp cylinder 9.

[0025] During use, it is necessary to install the clamping tool in the sinking groove 3 in advance, and then vertically place the clamp cylinder body 9 to be processed into the mounting hole 41 on the fixing seat 4. Due to the existence of the sinking groove 3, the bottom of the clamp cylinder body 9 is placed below the ground 2, which in disguise "lowers" the length of the clamp rod body 9 or the height in the vertical state, so that it can be adapted to the traditional radial drilling machine 1. Since the position of the sinking groove 3 is within the maximum rotation adjustment range of the radial drilling machine 1, the drill bit of the radial drilling machine 1 can be directly aligned with the clamp cylinder body 9 to complete the vertical drilling cylinder oil channel processing operation.

[0026] For fixing the clamp cylinder 9, see Figure 1 and Figure 2After the clamp cylinder 9 is placed in the fixing seat 4, the central opening on the clamp cylinder 9 can just cooperate with the fastening assembly. Specifically, the height of the positioning column 5 is just flush with the end surface height of the single-side cylinder of the clamp cylinder 9, that is, the bottom wall height 2 at the central opening, so that the clamping plate 7 can be directly pressed horizontally between the clamp cylinder 9 and the positioning column 5, and then tightened by the fastening bolts 8, so that the clamp cylinder 9 is fixed on the fixing seat 4, completing the fixation of the clamp cylinder 9.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
