Description

Technical Field

[0001] This utility model belongs to the field of tapping machine technology, and specifically relates to a tapping fixture for a tapping machine. Background Technology

[0002] A tapping machine is a machining device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges, using either through holes or blind holes of different specifications. Tapping machines are also called thread tapping machines, automatic tapping machines, etc. With the continuous advancement of industrial technology, the types and models of tapping machines have become increasingly diverse to meet the needs of different industries and fields.

[0003] A tapping fixture for a tapping machine is disclosed in Chinese Patent Network CN220347390U. It includes a worktable, a fixed block on the worktable, a sliding groove on each fixed block, a sliding rod slidably connected in the sliding groove, a clamping block connected to the sliding rod, a fixing structure between the sliding rod and the fixed block, a slot on the clamping block at a 90-degree angle, and several fixed blocks, sliding rods and clamping blocks on the worktable. A spring is sleeved on the sliding rod.

[0004] In the aforementioned case, although the tapping machine's tapping fixture can fix various different workpieces by using several clamping blocks to hold the workpiece, the process of clamping the workpiece requires manual adjustment and locking of each clamping block individually. This operation is cumbersome, consumes a lot of time and manpower, resulting in slow clamping efficiency, making it difficult to meet the needs of mass production and unfavorable for practical use.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is a tapping fixture for a tapping machine, including a base. Guide components are evenly and symmetrically installed inside the base. There are four sets of guide components. Clamping components are installed on the guide components. Locking components are installed on the clamping components. Fixing components and adjusting components are installed inside the base. The adjusting components are used to change the height of the fixing components so that the fixing components drive the locking components to move and lock them with the guide components. Thus, the position of the clamping components is locked by the locking components.

[0007] The guide assembly includes a guide rod, one end of which is mounted on the inner wall of the base. The clamping assembly is slidably mounted on the guide rod. A guide spring is mounted on the guide rod, one end of which contacts the inner wall of the base, and the other end of which contacts the surface of the clamping assembly.

[0008] Multiple guide grooves are evenly distributed around the center on the upper surface of the base. The number of guide grooves is the same as that of the clamping components, and they slide in a corresponding manner.

[0009] The clamping assembly includes a movable seat that is slidably mounted on a guide rod. A movable frame is mounted on the upper end of the movable seat and is slidably mounted in a guide groove. A clamping block is provided on the upper end of the movable frame and is used to clamp the workpiece.

[0010] The lower end of the movable base is provided with an installation groove. The locking component includes a locking block, which is slidably installed in the installation groove. The lower end of the locking block is located below the movable base, and the upper end of the locking block can contact the surface of the guide rod. Both sides of the upper surface of the locking block are provided with a return spring, and the upper end of the return spring contacts the top wall of the installation groove.

[0011] The fixing component includes a screw rod, the upper end of which is rotatably mounted on the inner top wall of the base. The fixing component also includes two fixing posts, which are vertically arranged inside the base. Fixing plates are threaded onto the screw rod, and the fixing plates are slidably mounted on the fixing posts. The upper surface of the fixing plates can contact the lower end of the locking block.

[0012] The adjustment assembly includes a worm gear and a rotating rod. The worm gear is coaxially mounted at the lower end of the screw. The rotating rod is horizontally inserted and rotatably mounted in the base. A worm is coaxially mounted on the rotating rod, and the worm meshes with the worm gear. A throttle handle is mounted on one end of the rotating rod.

[0013] The lower part of the guide rod is set as a plane, and the upper end of the locking block can contact the plane, and the plane is provided with anti-slip protrusions.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a rotating handle to drive a worm gear and screw, causing the fixed plate to gradually rise. This, in turn, causes the locking block to rise and contact the plane of the guide rod, ultimately locking it in place. This fixes the locking block and guide rod, allowing the moving block and clamping block to follow suit and become fixed simultaneously, firmly securing the workpiece. This eliminates the need for individual operation of each clamping component, enabling simultaneous fixing of clamping components in any position, thus improving installation efficiency and enhancing practicality.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 6 As shown:

[0027] This embodiment provides a tapping fixture for a tapping machine, including a base 1. Guide components 2 are evenly and symmetrically installed inside the base 1. There are four sets of guide components 2. Clamping components 3 are slidably installed on the guide components 2. Locking components 4 are installed on the clamping components 3. A fixing component 5 and an adjusting component 6 are installed inside the base 1. The adjusting component 6 is used to change the height of the fixing component 5 so that the fixing component 5 drives the locking component 4 to move and lock it with the guide components 2. Thus, the position of the clamping component 3 is locked by the locking component 4.

[0028] The workpiece can be placed on the upper surface of the base 1 manually, and the clamping component 3 can be positioned in contact with its four sides. Since the clamping component 3 is slidably mounted on the guide component 2, the clamping component 3 can change its position on the guide component 2 arbitrarily when the locking component 4 is not locked to the guide component 2, so as to adapt to workpieces of different sizes or shapes. After the workpiece is stably placed on the base 1 and the clamping component 3 is in contact with its surface, the adjusting component 6 can be moved by driving it. The adjusting component 6 drives the fixing component 5 to move upward, which in turn drives the locking component 4 to move upward. The locking component 4 gradually contacts the guide component 2 and finally locks it, thus fixing the clamping component 3 in a fixed state and preventing it from moving. This allows the clamping component 3 to perform positioning operations on the workpiece, ensuring its stability during tapping operations. This device eliminates the need to individually fix each clamping component 3, and can simultaneously fix clamping components 3 in any position, improving installation efficiency and enhancing practicality.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the guide assembly 2 includes a guide rod 7, one end of which is mounted on the inner wall of the base 1. The clamping assembly 3 is slidably mounted on the guide rod 7. A guide spring 8 is mounted on the guide rod 7. One end of the guide spring 8 contacts the inner wall of the base 1, and the other end contacts the surface of the clamping assembly 3. The guide spring 8 enables the clamping assembly 3 to have a reset capability on the guide rod 7, so that when the workpiece is placed in the center of the base 1, the clamping assembly 3 can always contact its surface and fix it. At the same time, when the workpiece is removed and the locking assembly 4 is in an unlocked state, the guide spring 8 can drive the clamping assembly 3 back to its original position.

[0030] like Figure 1 , Figure 3 , Figure 6 As shown, multiple guide grooves 9 are evenly distributed around the center of the upper surface of the base 1. The number of guide grooves 9 is the same as that of the clamping components 3, and they are slidably engaged in a one-to-one correspondence. The clamping components 3 include a movable seat 10, which is slidably mounted on the guide rod 7. A movable frame 11 is mounted on the upper end of the movable seat 10 and is slidably mounted in the guide groove 9. A clamping block 12 is provided on the upper end of the movable frame 11. The clamping block 12 is used to clamp the workpiece. When it is necessary to place the workpiece, the clamping block 12 can be pulled first so that the clamping block 12 drives the movable frame 11 and the movable seat 10 to move to the end of the guide groove 9 that is far from the center of the base 1, so that the guide spring 8 is compressed. Then the workpiece is placed in the center of the base 1. At this time, the clamping block 12 is no longer pulled. The clamping block 12 can automatically contact the surface of the workpiece through the elastic force of the guide spring 8, thereby fixing the position of the clamping block 12 by the locking component 4 to fix the workpiece.

[0031] The clamping block 12 is provided with a slot at a 90-degree angle so that it can match square workpieces. The clamping block and the slot are set with an arc transition so that there are no sharp corners between the clamping block and the slot. This allows the clamping block to clamp round workpieces without creating indentations. The front end of the slot is set with an arc shape so that the arc at the front end of the slot can easily insert the workpiece between several clamping blocks when in use.

[0032] like Figure 2 , Figure 6 , Figure 7 As shown, the lower end of the movable seat 10 has a mounting groove 13. The locking component 4 includes a locking block 14, which is slidably installed in the mounting groove 13. The lower end of the locking block 14 is located below the movable seat 10. The guide rod 7 is set as a plane at its lower part. The upper end of the locking block 14 can contact the plane, and the plane is provided with anti-slip protrusions. Both sides of the upper surface of the locking block 14 are provided with return springs 15. The upper end of the return spring 15 contacts the inner top wall of the mounting groove 13. In the initial state, the return spring 15 is in an uncompressed state, and the upper end of the locking block 14 does not contact the guide rod 7. When it is necessary to change the clamping block 12 to a fixed state to fix the workpiece, the fixing component 5 is raised by the adjusting component 6 so that the fixing component 5 and the locking block 14 are in contact. 4. When the lower end contacts the fixed component 5, as the fixed component 5 gradually rises, it will drive the return spring 15 to compress, causing the locking block 14 to move upward. The locking block 14 gradually contacts the plane set on the guide rod 7 and finally locks and clamps with it. The plane setting allows the locking block 14 to have higher friction with the guide rod 7, resulting in a more solid fixing effect. This fixes the locking block 14 and the guide rod 7 into a fixed state, causing the moving block to follow suit and become fixed, thereby fixing the clamping block 12 and firmly fixing the workpiece. When it is necessary to release the fixing operation between the locking block 14 and the guide rod 7, the fixed component 5 is driven to descend. At this time, the return spring 15 will drive the locking block 14 to descend rapidly, so that the locking block 14 is no longer clamped with the fixed block.

[0033] The locking block 14 is made of a highly wear-resistant material, which can improve its service life and ensure the locking force of the locking block 14. At the same time, it is equipped with an anti-slip groove at the top, which can increase its friction.

[0034] like Figure 2-7As shown, the fixing component 5 includes a screw 16, the upper end of which is rotatably mounted on the inner top wall of the base 1. The fixing component 5 also includes two fixing posts 17, which are vertically arranged inside the base 1. Fixing plates 18 are threaded onto the screw 16, and both fixing plates 18 are slidably mounted on the fixing posts 17. The upper surface of the fixing plates 18 can contact the lower end of the locking block 14. The adjusting component 6 includes a worm gear 19 and a rotating rod 20. The worm gear 19 is coaxially arranged at the lower end of the screw 16, and the rotating rod 20 is transversely inserted and rotatably mounted inside the base 1. A worm gear 21 is coaxially mounted on the moving rod 20. The worm gear 21 meshes with the worm wheel 19. A handle 22 is mounted on one end of the rotating rod 20. By rotating the handle 22, the worm gear 21 on the rotating rod 20 can be rotated, so that the worm gear 21 drives the worm wheel 19 to rotate, causing the screw 16 to rotate. This causes the fixed plate 18 to move vertically upward from the fixed column 17. As the fixed plate 18 gradually moves upward, it will come into contact with the locking block 14, making the locking block 14 and the guide rod 7 fixed, thus fixing the clamping block 12 and firmly fixing the workpiece.

[0035] The working principle of the tapping fixture for a tapping machine provided by this utility model is as follows: First, pull up the clamping block 12, so that the clamping block 12 drives the moving frame 11 and the moving seat 10 to move to the end of the guide groove 9 that is far from the center of the base 1, so that the guide spring 8 is compressed. Then, place the workpiece in the center of the base 1. At this time, the clamping block 12 is no longer pulled up. The clamping block 12 can automatically contact the surface of the workpiece through the elastic force of the guide spring 8. At this time, turn the handle 22, so that it drives the worm 21 to rotate, drives the worm wheel 19 and the screw 16 to rotate, thereby driving the fixed plate 18 to gradually rise, driving the locking block 14 to gradually rise, the reset spring 15 is compressed, and the locking block 14 gradually contacts the plane set on the guide rod 7 and finally locks and clamps it, so that the locking block 14 and the guide rod 7 become fixed, so that the moving block and the clamping block 12 become fixed in sync, and firmly fix the workpiece.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
