Description

Technical Field

[0001] This utility model relates to the field of tapping equipment technology, and in particular to a universal joint device for a tapping machine. Background Technology

[0002] Tapping machines are commonly used machining equipment for processing internal threads on workpieces, and are widely used in industries such as machinery manufacturing, hardware processing, automobiles, and electronics. By driving the tap to rotate and feed it axially, the tap cuts the workpiece material to form a standard internal thread structure.

[0003] The universal joint base is a key component used to provide mounting support for tapping machines and adjust the position of the tap. Its core function is to allow the tap to deflect at multiple angles and be flexibly positioned during the machining process, thereby adapting to the thread machining needs of complex workpieces or non-standard positions.

[0004] Currently, traditional universal joint devices are often fixed to the worktable with bolts. Although the position of the tap can be adjusted by the universal joint during tapping operations, due to the wide variety of workpieces being processed, there are often dead zones that cannot meet the requirements when adjusting the tap position by the universal joint. Therefore, the inventor has proposed an improved universal joint device. Utility Model Content

[0005] The purpose of this invention is to provide a universal joint device for a tapping machine, which allows for flexible adjustment of the installation position of the universal joint device to meet the needs of more processing areas.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a universal joint device for a tapping machine, including a worktable, a universal joint being provided on the worktable, and a tapping assembly being installed at the end of the universal joint;

[0007] The workbench is equipped with a movable guide rail, and a fixed component is installed inside the movable guide rail that can move along it. The bottom end of the universal joint is installed on the fixed component, and the installation position of the universal joint can be adjusted through the fixed component.

[0008] A further feature of this invention is that the movable guide rail includes a first track and a second track disposed on the workbench, the first track and the second track intersecting each other.

[0009] By adopting the above technical solution, more positional options are available for the movement of the universal joint.

[0010] A further feature of this invention is that the fixing component includes a mounting post whose upper surface is fixedly connected to a universal joint and a mounting sleeve whose upper surface is in sliding contact with the worktable, and the mounting post and the mounting sleeve are fixed together by a sliding post.

[0011] By adopting the above technical solution, the three components can be kept in a unified state, making it convenient to move the universal joint.

[0012] A further feature of this invention is that the bottom surface of the mounting column is in contact with the workbench, the mounting column, the mounting tube, and the sliding column are coaxial, and the outer side of the sliding column is in sliding contact with the first track and the second track.

[0013] By adopting the above technical solution, the universal joint can be moved along the first or second track by applying a thrust to the mounting column.

[0014] A further feature of this invention is that a positioning component is installed on the outside of the adhesive tube.

[0015] By adopting the above technical solution, the universal joint is fixed after the position is moved by the positioning component.

[0016] A further feature of this invention is that the positioning component includes a pressure ring slidably connected to the outside of the adhesive cylinder, a control component fixedly connected to the outside of the pressure ring, and a driving component for driving the pressure ring to move.

[0017] By adopting the above technical solution, the contact tightness between the pressure ring and the worktable is improved.

[0018] A further feature of this invention is that a slide rail is provided on the outer side of the adhesive tube, and the control component includes a slide frame that is slidably connected to the slide rail on the outer side and a driven block that is fixedly connected to the inner end of the slide frame. The slide frame is fixed to the outer side of the pressure ring.

[0019] By adopting the above technical solution, it is easy to make the pressure ring fit tightly or separate from the bottom surface of the worktable.

[0020] A further feature of this invention is that: an inclined groove is provided on the side of the driven block away from the slide, and the driving assembly includes a pressure rod that slides along the inner wall of the inclined groove at one end and a synchronization ring that is fixedly connected to the other end of the pressure rod. A bracket is fixedly installed inside the synchronization ring, and the bracket is fixed to the motor output shaft.

[0021] By adopting the above technical solution, the motor drives the bracket to rotate, thereby enabling the synchronous ring to drive the pressure rod to rotate.

[0022] A further feature of this invention is that the number of control components is set to four.

[0023] By adopting the above technical solution, the slide rail and pressure bar are also provided in four places, which can provide stable pressure to the pressure ring.

[0025] By adopting the above technical solution, the output shaft of the motor is fixed to the bracket after passing through the mounting plate.

[0026] The beneficial effects of this utility model are:

[0027] The universal joint can drive the tapping assembly and perform daily tapping operations. When there is a dead zone in the adjustment of the universal joint, the drive assembly can move the pressure ring, allowing the pressure ring to separate from the worktable. Then, the universal joint can be adjusted along the moving guide rail via the mounting column, thereby adjusting the universal joint to the appropriate area to meet the processing position requirements of the tapping machine. The drive assembly also ensures that the mounting column can be stably fixed to the worktable surface via the pressure ring during operation, improving installation stability, reducing dead zones in the universal joint during use, and improving the performance and processing convenience.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] This utility model embodiment specifically provides a universal joint device for a tapping machine. Please refer to [link / reference]. Figures 1-5 The system includes a worktable 1, on which a universal joint 11 is provided, and a tapping assembly 12 is installed at the end of the universal joint 11. The worktable 1 is also provided with a fixture 13 for holding the workpiece. The workpiece held in the fixture 13 is tapped by the tapping assembly 12. In practice, the above-mentioned components are all existing mature components, so their specific functions and structures will not be described in detail.

[0037] The workbench 1 is provided with a movable guide rail 2, and a fixed component 3 is provided inside the movable guide rail 2, which can be moved along it. The bottom end of the universal joint 11 is installed on the fixed component 3. The installation position of the universal joint 11 can be adjusted through the fixed component 3, thereby improving the flexibility and convenience of tapping operations.

[0038] Specifically, the movable guide rail 2 includes a first rail 21 and a second rail 22 provided on the worktable 1. The first rail 21 and the second rail 22 intersect each other and are perpendicular to each other. The second rail 22 is provided in three places to provide more position options for the movement of the universal joint 11.

[0039] Furthermore, the fixing component 3 includes a mounting post 5 whose upper surface is fixedly connected to the universal joint 11 and a contact sleeve 6 whose upper surface is in sliding contact with the worktable 1. The mounting post 5 and the contact sleeve 6 are fixed together by a sliding post 7, so that the three can be kept in a unified state, which facilitates the movement of the universal joint 11.

[0040] Specifically, the bottom surface of the mounting column 5 is in contact with the workbench 1. The mounting column 5, the mounting sleeve 6, and the sliding column 7 are coaxial, and the outer side of the sliding column 7 is in sliding contact with the first track 21 and the second track 22. By applying a thrust to the mounting column 5, the universal joint 11 can be moved along the first track 21 or the second track 22 to achieve a change in position.

[0041] During implementation, a positioning component 8 is installed on the outside of the adhesive tube 6, which is used to fix the universal joint 11 after it has moved to a new position.

[0042] Furthermore, the positioning component 8 includes a pressure ring 81 that is slidably connected to the outside of the adhesive cylinder 6, a control component 82 that is fixedly connected to the outside of the pressure ring 81, and a drive component 83 that drives the pressure ring 81 to move. When the universal joint 11 is fixed, the top surface of the pressure ring 81 is tightly abutted against the worktable 1. The top surface of the pressure ring 81 is a rough surface. In practice, soft pads or anti-slip textures can also be added to improve the tightness of the contact between the pressure ring 81 and the worktable 1. When the pressure ring 81 applies force to the bottom surface of the worktable 1 and adheres tightly, the mounting column 5 is fixed, thereby fixing the universal joint 11.

[0043] Specifically, a slide rail 61 is provided on the outer side of the coating cylinder 6. The control component 82 includes a slide frame 821 that is slidably connected to the slide rail 61 on the outer side and a driven block 822 that is fixedly connected to the inner end of the slide frame 821. The slide frame 821 is fixed to the outer side of the pressure ring 81, so that the pressure ring 81 can be driven to move up and down synchronously by sliding the slide frame 821 up and down, thereby facilitating the pressure ring 81 to be attached to or separated from the bottom surface of the worktable 1.

[0044] The driven block 822 has a sloping groove 823 on the side away from the slide 821. The drive assembly 83 includes a pressure rod 831 with one end sliding along the inner wall of the sloping groove 823 and a synchronization ring 832 fixedly connected to the other end of the pressure rod 831. When the sloping groove 823 is tilted upward in the direction of looking up, the sloping groove 823 gradually tilts upward along the clockwise direction of the synchronization ring 832, so that when the synchronization ring 832 rotates counterclockwise, it can gradually press the sloping groove 823 upward through the pressure rod 831, so that the pressure ring 81 is forced to move upward and press against the bottom surface of the worktable 1.

[0045] During implementation, a bracket 833 is fixedly installed inside the synchronization ring 832. The bracket 833 is fixed to the output shaft of the motor 834. The motor 834 drives the bracket 833 to rotate, thereby enabling the synchronization ring 832 to drive the pressure rod 831 to rotate. Through the self-locking function of the motor 834, the pressure ring 81 is moved up or down and positioned, thus completing the position adjustment of the universal joint 11.

[0046] The number of control components 82 is set to four, that is, the number of slide rails 61 and pressure rods 831 is also set to four, so as to provide stable pressure to pressure ring 81 and improve the fixing effect.

[0047] The inner wall of the tube 6 is fixedly installed with a mounting plate 62. The outer side of the motor 834 is fixedly connected to the mounting plate 62. The output shaft of the motor 834 passes through the mounting plate 62 and is fixed to the bracket 833, so as to facilitate and stably drive the bracket 833 to rotate.

[0048] A collection box 4 is placed under the workbench 1, which can directly sweep the debris on the surface of the workbench 1 into the collection box 4 for collection and treatment when cleaning the surface, which is very convenient.

The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.
