Description

Technical Field

[0001] The utility model belongs to the technical field of drilling machines, and particularly relates to a tool locking tooling with multi - specification adaptability for a drilling machine. Background Art

[0002] A drilling machine mainly refers to a machine tool for machining holes in workpieces. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The structure of the drilling machine is simple, and the machining accuracy is relatively low. It can drill through - holes and blind - holes.

[0003] When the drilling machine equipment processes workpieces to different degrees, it is necessary to replace the tool to complete operations such as reaming, countersinking, boring, or tapping. Most tools are fixed by threads and bolts. When replacing the tool, it is necessary for workers to disassemble multiple bolts manually, which not only reduces the replacement efficiency, increases the labor of manual replacement, but also reduces the machining efficiency of the drilling machine equipment. Moreover, when the drilling machine replaces different tools, the lengths and thicknesses of these tools are sometimes different, resulting in inconvenience in effectively fixing the tools according to their thicknesses and lengths when the drilling machine fixes different tools, and leading to safety accidents where the tool detaches from the drilling machine during use.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] In view of the problems in the related art, the utility model provides a tool locking tooling with multi - specification adaptability for a drilling machine to overcome the above - mentioned technical problems existing in the prior related art.

[0006] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model provides a tool locking tooling with multi - specification adaptability for a drilling machine, which includes a telescopic housing. Clamping mechanisms are arranged at both ends inside the telescopic housing. A locking mechanism is arranged between the two clamping mechanisms, and a positioning mechanism is arranged outside the clamping mechanism.

[0008] The clamping mechanism includes an adjustment housing. The two adjustment housings are respectively located at both ends inside the telescopic housing and are fixedly connected to the telescopic housing. A plurality of positioning columns are slidably connected inside the adjustment housing. A positioning block is slidably connected to the outside of one end of the positioning column located inside the adjustment housing. A second spring is sleeved outside the positioning column, and both ends of the second spring are respectively fixedly connected to the positioning block and the adjustment housing.

[0009] Furthermore, the locking mechanism includes a fixed housing. A groove adapted to the fixed housing is opened inside the adjustment housing. The fixed housing is located inside the groove of the adjustment housing and is slidably connected to the adjustment housing.

[0010] Furthermore, a first telescopic column is fixedly connected to the outer side of the fixed shell. The top end of the first telescopic column is rotatably connected to a first bevel gear. A locking column is fixedly connected to the side of the first bevel gear away from the first telescopic column. The locking column is located inside the telescopic housing and is slidably connected to the telescopic housing.

[0011] Furthermore, a first spring is sleeved on the outer side of the first telescopic column. The two ends of the first spring are respectively fixedly connected to the two ends of the first telescopic column.

[0012] Furthermore, the positioning mechanism includes a moving ring. The moving ring is located on the outer side of the adjusting shell and is slidably connected to the adjusting shell. A plurality of fixing blocks are fixedly connected to the outer side of the moving ring. The number of the fixing blocks is equal to the number of the positioning columns. A connecting rod is rotatably connected between the fixing block and the positioning column.

[0013] Furthermore, threaded rods are arranged on the outer side of the moving ring. The thread directions of the two threaded rods are opposite. The two threaded rods are respectively located inside two of the fixing blocks and are threadedly connected to the fixing blocks. The two ends of the threaded rod are rotatably connected to a fixing plate. The fixing plate is fixedly connected to the adjusting shell.

[0014] Furthermore, two support plates are fixedly connected to the top of the fixed shell. The two support plates are respectively located on both sides of the first telescopic column. An annular sliding groove is formed on the side surface of the support plate and is rotatably connected to a second bevel gear. The second bevel gear is meshed with the first bevel gear. A second telescopic column is fixedly connected to the side surface of the second bevel gear. A threaded rod is fixedly connected to the end of the second telescopic column away from the second bevel gear.

[0015] The utility model has the following beneficial effects:

[0016] 1. By moving the moving ring, the fixing block pushes the connecting rod, so that the positioning column slides inside the adjusting shell, thereby pushing the positioning block to move. In this way, multiple positioning blocks can contact cutters with different thicknesses to clamp and fix cutters with different thicknesses. By moving the adjusting shell, the fixed shell is located inside the adjusting shell, so that multiple positioning blocks can contact both ends of the parts of cutters with different lengths located inside the device, thereby clamping and fixing cutters with different lengths. In this way, multi-point clamping and fixing of cutters with different thicknesses and lengths can be achieved, avoiding the cutter from detaching from the drilling machine during processing.

[0017] 2. In the present utility model, by rotating the locking column, the first bevel gear drives the two second bevel gears to rotate, thereby driving the threaded rod to drive the moving ring to move, so as to quickly complete the disassembly and replacement of the tool, avoiding the need for manual disassembly of multiple bolts during tool replacement, which increases the labor of workers and reduces the processing efficiency of the drilling machine. Through the first spring, the first telescopic column can drive the first bevel gear to disengage from the second bevel gear, so that the two second bevel gears are no longer in transmission connection. In this way, when a certain threaded rod drives the moving ring to move during the processing of the drilling machine, the other moving ring can clamp and fix the tool, thereby reducing the probability of the tool detaching from the drilling machine.

[0018] Of course, when implementing any product of the present utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the utility model.

[0030] Please refer to Figures 1-6 As shown, the present utility model is a tool locking tool for multi - specification adaptation of a drilling machine, including a telescopic housing 1. Clamping mechanisms 3 are provided at both ends inside the telescopic housing 1. A locking mechanism 2 is provided between the two clamping mechanisms 3. A positioning mechanism 4 is provided outside the clamping mechanism 3.

[0031] The clamping mechanism 3 includes an adjusting housing 301. The two adjusting housings 301 are respectively located at both ends inside the telescopic housing 1 and are fixedly connected to the telescopic housing 1. A plurality of positioning columns 302 are slidably connected inside the adjusting housing 301. A positioning block 303 is slidably connected to the outside of one end of the positioning column 302 inside the adjusting housing 301. A second spring 304 is sleeved on the outside of the positioning column 302. The two ends of the second spring 304 are respectively fixedly connected to the positioning block 303 and the adjusting housing 301.

[0032] When a tool needs to be replaced, place the tool inside one of the adjusting shells 301. When the tool enters, it pushes the positioning block 303 to move and slide on the outside of the positioning column 302. At the same time, when the positioning block 303 moves, the second spring 304 fixedly connected to its top can be compressed. When the positioning block 303 loses the thrust, under the action of the self-elastic force of the second spring 304, it can push the positioning block 303 to clamp and fix the tool. Furthermore, during the continuous movement of the tool, it can cooperate with another set of clamping mechanisms 3, repeat the above steps and clamp and fix the tool, so as to be able to perform multi-point clamping and fixing on the tool.

[0033] Through the action of the self-elastic force of the second spring 304 of the present utility model, it can push the positioning block 303 to clamp and fix the outside of the tool, avoiding the position of the tool not being limited when the tool is locked, resulting in the deviation of the position of the tool after subsequent tool locking. Then rotate the locking mechanism 2 to move the positioning mechanism 4, thereby pushing the clamping mechanism 3 to move and clamp and fix the outside of the tool, so as to clamp and fix tools of different thicknesses and lengths.

[0034] In one embodiment, for the above-mentioned locking mechanism 2, the locking mechanism 2 includes a fixed shell 201. A groove adapted to the fixed shell 201 is opened inside the adjusting shell 301. The fixed shell 201 is located inside the groove of the adjusting shell 301 and is slidably connected to the adjusting shell 301.

[0035] By manually pushing the adjusting shell 301 according to the length of the tool when installing the tool, the fixed shell 201 can slide inside the adjusting shell 301, so that the device can perform multi-point clamping on both sides of the two ends where the tool needs to be fixed according to the length of the tool.

[0036] In one embodiment, for the above-mentioned fixed shell 201, a first telescopic column 205 is fixedly connected to the outside of the fixed shell 201. A first bevel gear 202 is rotatably connected to the top of the first telescopic column 205. A locking column 204 is fixedly connected to the side of the first bevel gear 202 away from the first telescopic column 205. The locking column 204 is located inside the telescopic housing 1 and is slidably connected to the telescopic housing 1.

[0037] By manually rotating the locking column 204 to make the first bevel gear 202 rotate, and driving the second bevel gear 408 to rotate. Since the two ends of the second telescopic column 406 are respectively fixedly connected to the second bevel gear 408 and the threaded rod 404, the threaded rod 404 is rotated accordingly, and the positioning mechanism 4 is moved through the fixing block 402 threadedly connected to the outside, so that when the device fixes the tool, only by rotating the locking column 204 alone, multi-point clamping of the tool can be performed.

[0038] In one embodiment, for the above-mentioned first telescopic column 205, a first spring 203 is sleeved outside the first telescopic column 205, and both ends of the first spring 203 are fixedly connected to both ends of the first telescopic column 205 respectively.

[0039] Through the elastic force of the first spring 202 itself, the first bevel gear 202 fixedly connected to its top can be pushed to rise, so that the first bevel gear 202 is disengaged from the second bevel gear 408, thereby avoiding touching the threaded rod 404.

[0040] In one embodiment, for the above-mentioned positioning mechanism 4, the positioning mechanism 4 includes a moving ring 401. The moving ring 401 is located outside the adjusting shell 301 and is slidably connected to the adjusting shell 301. A plurality of fixing blocks 402 are fixedly connected to the outside of the moving ring 401. The number of the fixing blocks 402 is equal to the number of the positioning columns 302. A connecting rod 403 is rotatably connected between the fixing block 402 and the positioning column 302.

[0041] By pushing the moving ring 401 to move, the fixing blocks 402 fixedly connected to its outer surface can be moved. When the fixing blocks 402 move, the connecting rods 403 hinged inside them can be driven to move. Since one end of the connecting rod 403 is hinged to one end of the positioning column 302, and the outer surface of the positioning column 302 is slidably arranged inside the adjusting shell 301, when the connecting rod 403 moves, the positioning column 302 can be driven to slide inside the adjusting shell 301, and the positioning block 303 fixedly connected to one end of it can be driven to move, thereby facilitating the adjustment of the position of the positioning block 303 so that it can be suitable for clamping and fixing tools of different thicknesses.

[0042] In one embodiment, for the above-mentioned threaded rod 404, threaded rods 404 are arranged outside the moving ring 401. The thread directions of the two threaded rods 404 are opposite. The two threaded rods 404 are respectively located inside two of the fixing blocks 402 and are threadedly connected to the fixing blocks 402. Both ends of the threaded rod 404 are rotatably connected to a fixing plate 407, and the fixing plate 407 is fixedly connected to the adjusting shell 301.

[0043] By rotating the threaded rod 404, the fixing blocks 402 threadedly connected to its outside can be moved. Since the fixing blocks 402 are fixedly connected to the moving ring 401, a plurality of groups of fixing blocks 402 can be moved together, so that a plurality of groups of connecting rods 403 can be pushed simultaneously, so that a plurality of groups of positioning columns 302 can push a plurality of groups of positioning blocks 303 to clamp the tool at multiple points.

[0044] In one embodiment, for the above-mentioned support plate 405, two support plates 405 are fixedly connected to the top of the fixed housing 201. The two support plates 405 are respectively located on both sides of the first telescopic column 205. An annular chute is formed on the side surface of the support plate 405 and is rotatably connected to a second bevel gear 408. The second bevel gear 408 is meshed with a first bevel gear 202. A second telescopic column 406 is fixedly connected to the side surface of the second bevel gear 408. One end of the second telescopic column 406 away from the second bevel gear 408 is fixedly connected to a threaded rod 404.

[0045] The position of the second bevel gear 408 can be supported and limited by the support plate 405, enabling the first bevel gear 202 to be meshed with the second bevel gear 408. Since the two ends of the second telescopic column 406 are respectively fixedly connected to the second bevel gear 408 and the threaded rod 404, after the length of the device is adjusted according to the length of the tool to be fixed, when the distance between the threaded rod 404 and the second bevel gear 408 changes, the threaded rod 404 can still rotate following the second bevel gear 408.

[0046] In summary, by means of the above technical solution of the present invention, the telescopic housing 1 is fixedly installed with the output end of the drilling machine. When a tool needs to be replaced, the tool is placed into the interior of one of the adjustment housings 301. When the tool enters, it pushes the positioning block 303 to move and slide on the outside of the positioning column 302. At the same time, when the positioning block 303 moves, the second spring 304 fixedly connected to its top end can be compressed. When the positioning block 303 loses the thrust, under the action of the self-elastic force of the second spring 304, it can push the positioning block 303 to clamp and fix the tool. Furthermore, during the continuous movement of the tool, it can cooperate with another set of clamping mechanisms 3, repeat the above steps to clamp and fix the tool. Then, manually move the adjustment housing 301 to make the fixed housing 201 enter the interior of the adjustment housing 301. Then, press the locking column 204 to make the first bevel gear 202 contact the second bevel gear 408, and then rotate the locking column 204 to make the first bevel gear 202 drive the second bevel gear 408 to rotate. Then, the second bevel gear 408 enables the second telescopic column 406 to drive the threaded rod 404 to rotate, so that one of the fixing blocks 402 moves and drives the remaining fixing blocks 402 to move through the moving ring 401. The multiple fixing blocks 402 move together, and thus the positioning column 302 can push the positioning block 303 to move to clamp the tool through the connecting rod 403.

[0047] Through the above technical solutions: 1. By moving the moving ring 401, the fixed block 402 is driven to push the connecting rod 403, so that the positioning column 302 slides inside the adjusting housing 301, thereby pushing the positioning block 303 to move. In this way, multiple positioning blocks 303 can contact cutters of different thicknesses to clamp and fix cutters of different thicknesses. By moving the adjusting housing 301, the fixed housing 201 is located inside the adjusting housing 301, so that multiple positioning blocks 303 can contact both ends of the parts of cutters of different lengths located inside the device to clamp and fix cutters of different lengths. In this way, multi-point clamping and fixing of cutters of different thicknesses and lengths is achieved, avoiding the cutter detaching from the drilling machine during processing.

[0048] 2. In the present utility model, by rotating the locking column 204, the first bevel gear 202 drives two second bevel gears 408 to rotate, so that the threaded rod 404 drives the moving ring 401 to move, thereby quickly completing the disassembly and replacement of the cutter. This avoids the need to manually disassemble multiple bolts during cutter replacement, which increases the labor of workers and reduces the processing efficiency of the drilling machine. Through the first spring 203, the first telescopic column 205 can drive the first bevel gear 202 to disengage from the second bevel gear 408, so that the two second bevel gears 408 are no longer in driving connection. In this way, when a certain threaded rod 404 drives the moving ring 401 to move during the processing of the drilling machine, the other moving ring 401 can clamp and fix the cutter, thereby reducing the probability of the cutter detaching from the drilling machine.
