Description

Technical Field

[0001] This utility model belongs to the technical field of tapping devices, specifically relating to a tapping device for machining mechanical parts. Background Technology

[0002] Tapping devices are used in the machining of mechanical parts. These devices are used to machine threads on workpieces, and they come in various types and functions to suit different industrial needs. However, existing tapping devices typically require multiple people to assist in changing taps, making the overall operation quite difficult and limiting their functionality.

[0003] The existing patent with publication number CN220497978U discloses a benchtop tapping machine that facilitates tap replacement. It is equipped with a support frame, fixed handles, ring springs, movable rods, mounting blocks, positioning blocks, and tap body. In use, the operator pulls the two fixed handles, which compresses the two ring springs. This causes the movable rod to drive the two mounting blocks to move in opposite directions, disengaging the mounting blocks from the positioning blocks and thus releasing the restriction on the tap body.

[0004] However, the above method requires pulling two fixed handles simultaneously when disassembling the tap, and there are many parts that require external force. Furthermore, during the installation process, not only does someone need to pull the fixed handles, but someone else also needs to push the tap in, which cannot be done by one person, thus increasing the difficulty of operation and having certain limitations. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a tapping device for machining mechanical parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tapping device for machining mechanical parts includes a base, a connecting rod fixedly mounted on the top of the base, a mounting box slidably mounted on the connecting rod in a vertical direction, a fixed seat and a sliding ring rotatably mounted on the bottom of the mounting box, the sliding ring slidably fitting onto the outer surface of the fixed seat; a second elastic element is provided inside the sliding ring, a tap is engaged inside the fixed seat, and several engagement grooves are formed on the outer surface of the tap; several locking blocks are slidably disposed inside the fixed seat, each locking block having a first elastic element; a mating block is fixedly mounted at one end of each locking block, the mating block engaging with the engagement grooves one-to-one, and a trapezoidal groove is formed at the other end of each locking block; several clearance grooves are formed inside the sliding ring, and a fixed block is fixedly mounted in each clearance groove, one end of the fixed block being inclined and engaging with the trapezoidal grooves one-to-one.

[0008] Furthermore, the top of the base is provided with a clamping assembly, which includes a first electric push rod. Two first electric push rods are fixedly installed on the base, and the two first electric push rods are symmetrically arranged on the two side walls of the base. The telescopic shaft of each first electric push rod is fixedly connected to a card seat. The two card seats are arranged facing each other, and both card seats are slidably engaged with the top of the base.

[0009] Furthermore, a second electric push rod is fixedly installed on the top of the connecting rod, and the telescopic shaft of the second electric push rod is fixedly connected to the top of the mounting box.

[0010] Furthermore, a motor is fixedly installed inside the mounting box, and the output shaft of the motor is coaxially and fixedly connected to the top of the mounting base.

[0011] Furthermore, the second elastic element includes a fixed rod, which is slidably disposed inside the sliding ring. The bottom of the fixed rod is located inside the sliding ring and is integrally provided with a disc. A second spring is sleeved on the outer surface of the sliding ring. The bottom of the second spring is fixedly connected to the top of the disc, and the top of the second spring is fixedly connected to the top inner wall of the sliding ring. The top of the fixed rod slidably passes through the sliding ring and is fixedly disposed with a T-shaped block. The bottom of the mounting box is provided with an annular T-shaped groove that slidably engages with the T-shaped block.

[0012] Furthermore, the first elastic element includes a limiting ring, and the outer surface of each block is both fixedly fitted with a limiting ring and a first spring; one end of the first spring is fixedly connected to the limiting ring, and the other end of the first spring is fixedly connected to the fixed seat.

[0013] This application has the following beneficial effects:

[0014] 1. By installing multiple locking blocks, the limiting effect on the tap can be improved, ensuring the stability of the tap during operation. Furthermore, regardless of the number of locking blocks set, this solution only requires pulling down the sliding ring to drive all the locking blocks to slide synchronously, allowing the locking blocks to release the limiting and locking of the tap. This makes the operation more convenient and does not require the assistance of multiple people, thereby ensuring the stability of the tap while reducing the difficulty of disassembly and installation.

[0015] 2. In this design, the sliding ring is wrapped around the outside of the fixed base, which makes it easier for the operator to apply tension to the sliding ring, further reducing the difficulty of operation and improving the overall practical effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A tapping device for machining mechanical parts includes a base 1. The top of the base 1 is provided with a clamping assembly and a connecting rod 4 is fixedly installed in the vertical direction. The clamping assembly includes a first electric push rod 2. Two first electric push rods 2 are fixedly installed on the base 1 and are symmetrically arranged on the two side walls of the base 1. The telescopic shaft of each first electric push rod 2 is fixedly connected to a retaining seat 3. The two retaining seats 3 are arranged facing each other and are slidably engaged with the top of the base 1.

[0024] The two first electric push rods 2 are activated, causing the two clamping seats 3 to slide towards each other, thereby clamping and limiting the workpiece to be processed.

[0025] A second electric push rod 5 is fixedly installed on the top of the connecting rod 4. The telescopic shaft of the second electric push rod 5 is fixedly mounted in a mounting box 6. A motor 7 is fixedly installed inside the mounting box 6. The output shaft of the motor 7 extends rotatably out of the mounting box 6 and is coaxially fixedly mounted in a fixed seat 8. A sliding ring 13 is coaxially slidably sleeved on the outer surface of the fixed seat 8. The sliding ring 13 is provided with several second elastic elements, which facilitate the reset of the sliding ring 13 after sliding.

[0026] The second elastic element includes a fixed rod 16, which is slidably disposed within the sliding ring 13. The bottom of the fixed rod 16 is located within the sliding ring 13 and is integrally formed with a disc. A second spring 17 is sleeved on the outer surface of the sliding ring 13. The bottom of the second spring 17 is fixedly connected to the top of the disc, and the top of the second spring 17 is fixedly connected to the top inner wall of the sliding ring 13. The top of the fixed rod 16 slidably passes through the sliding ring 13 and is fixedly disposed with a T-shaped block 18. The bottom of the mounting box 6 has an annular T-shaped groove that is limited and slidably engaged with the T-shaped block 18.

[0027] Pulling down the sliding ring 13 will compress the second spring 17. When the sliding ring 13 is released, it will return to its original position under the elastic action of the second spring 17.

[0028] The fixed base 8 has a tap 9 internally engaged. Several engagement grooves 23 are formed on the outer surface of the upper end of the tap 9, arranged in a circular array along the central axis of the tap 9. The fixed base 8 also has several movable slots, each containing a rectangular locking block 10. Each locking block 10 has a first elastic element, which is used to reset the locking block 10 after it has moved.

[0029] The first elastic element includes a limiting ring 21. Each locking block 10 is fixedly fitted with the limiting ring 21 and a first spring 12 on its outer surface located in the moving groove. The limiting ring 21 limits the sliding within the moving groove. One end of the first spring 12 is fixedly connected to the limiting ring 21, and the other end of the first spring 12 is fixedly connected to the inner wall of the moving groove.

[0030] Each locking block 10 has a fixed mating block 22 at one end. The number of mating blocks 22 and the number of locking slots 23 are equal and correspond one-to-one. Each mating block 22 is engaged with the corresponding locking slot 23 in a transmission engagement. The other end of each locking block 10 is located inside the sliding ring 13. Each locking block 10 has a trapezoidal groove 20 at the end inside the sliding ring 13, and the trapezoidal groove 20 has an inclined surface 11.

[0031] A plurality of clearance grooves 15 are formed inside the sliding ring 13, and a fixing block 14 is fixedly installed in each clearance groove 15. The fixing block 14 is fixedly installed on the top inner wall of the sliding ring 13, and the bottom of the fixing block 14 is inclined. The number of fixing blocks 14 is equal to that of the locking blocks 10 and they correspond one-to-one. The inclined end of each fixing block 14 is in transmission engagement with the inclined surface 11 of the trapezoidal groove 20 formed in the corresponding locking block 10.

[0032] Working principle: When in use, place the mechanical part to be tapped on the base 1, start the two first electric push rods 2, so that the two clamps 3 slide towards each other, thereby centering and clamping the part to be processed.

[0033] The second electric push rod 5 is activated, and its telescopic shaft pushes the tap 9 closer to the workpiece. During this process, the motor 7 is activated, and its output shaft drives the tap 9 to rotate via the fixed seat 8, thereby tapping the mechanical part. The rotation of the fixed seat 8 also drives the sliding ring 13 to rotate synchronously via the locking block 10. The rotation of the sliding ring 13 causes the T-shaped block 18 at the top of the fixed rod 16 to slide within the T-shaped groove.

[0034] When tap 9 needs to be disassembled and replaced, the operator only needs to pull down sliding ring 13. During the process of pulling down sliding ring 13, the compression deformation of second spring 17 gradually increases.

[0035] During the process of pulling down the sliding ring 13, the clearance groove 15 gradually moves to a position parallel to the bottom of the locking block 10. As the pull continues, the inclined end of the fixing block 14 contacts the inclined surface 11 of the trapezoidal groove 20, and the two slide against each other, causing the locking block 10 to slide away from the tap 9. During this process, the first spring 12 is gradually compressed, the locking block 10 gradually passes through the clearance groove 15, and the mating block 22 gradually disengages from the locking groove 23, thereby releasing the restriction on the tap 9 and completing the disassembly operation of the tap 9.

[0036] Then, insert the tap 9 to be replaced into the fixed seat 8, loosen the sliding ring 13, and the sliding ring 13 will slide back to its original position under the elastic action of the second spring 17. The fixed block 14 gradually disengages from the trapezoidal groove 20, and the snap-fit ​​groove 23 is also snapped into the snap-fit ​​groove 23 under the elastic action of the first spring 12, thus completing the replacement of the tap 9.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
