DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] Please refer to Figures 1-3, A bench tapping machine shown in the figure, including a base 1. Inside the base 1, there is a rotating shaft 2. One end of the rotating shaft 2 is inserted and fitted with a motor 3. In the middle of the rotating shaft 2, there is a threaded connection with a slider 4. On one side of the slider 4, there is a second motor 5. On the other side of the slider 4, there is a tapping head 6. On one side of the tapping head 6, there is a fixture 7. Inside the fixture 7, there is an auxiliary positioning component 8. The auxiliary positioning component 8 includes a connecting head 801. On one side of the connecting head 801, there is a group of sliding rods 802. One end of the sliding rod 802 is fixedly connected to a pressing plate 803. At the central axis of the pressing plate 803, there is an adjusting rod 804. On both sides of the adjusting rod 804, there are springs 805. The adjusting rod 804 is threadedly connected to an adjusting plate 806. The adjusting plate 806 is slidably connected inside the fixture 7. In the present utility model, an auxiliary positioning component is provided inside the fixture. The auxiliary positioning component is composed of components such as a connecting head, sliding rods, a pressing plate, an adjusting rod, springs, and an adjusting plate. By matching the connecting head with the tapping head to form a connecting rod crank, during the tapping process, the auxiliary positioning component can ensure the stability and accuracy of the connecting rod crank. At the same time, it can prevent the tapping position deviation caused by the movement or instability of the workpiece, effectively avoiding the problem of over-tapping beyond the required position due to operation fatigue.

[0020] Furthermore, the fixture 7 includes a fixed bracket 701. Inside the fixed bracket 701, there is a sliding pair limit plate 702. The secondary limit plate 702 is rotatably connected to a positioning screw 703. The positioning screw 703 is rotatably connected to both sides of the main clamping plate 704. The main clamping plate 704 is slidably connected inside the fixed bracket 701. Through the fixture, rapid and accurate positioning of the workpiece is achieved. At the same time, in cooperation with the auxiliary positioning component, it ensures that the workpiece always remains stable during the tapping process, thereby avoiding the tapping error caused by the movement of the workpiece and enabling the fixture to adapt to a wider range of workpiece sizes.

[0021] Furthermore, an adjusting plate 806 is provided inside the main clamping plate 704. The adjusting plate 806 is slidably connected to the main clamping plate 704. A scale is provided at the bottom of the main clamping plate 704. By providing an adjusting plate inside the main clamping plate, the clamping force and position of the fixture can be adjusted more precisely. The adjusting plate can slide inside the main clamping plate. At the same time, through the scale, the operator can accurately know the sliding distance of the adjusting plate, thereby achieving precise control of the clamping position of the workpiece. This enables the operator to prevent the tapping position deviation caused by the movement or instability of the workpiece according to the actual size and shape of the workpiece, effectively avoiding the problem of over-tapping beyond the required position due to operation fatigue.

[0022] Furthermore, one end of the spring 805 is tightly pressed inside the main clamping plate 704, and the other end of the spring 805 is tightly pressed against one side of the pressure plate 803. The pressure plate 803 is slidably connected to the adjusting plate 806. By tightly pressing one end of the spring inside the main clamping plate and the other end tightly against one side of the pressure plate, the spring can provide a continuous pushing force between the main clamping plate and the pressure plate, ensuring the distance between the pressure plate and the adjusting plate, thereby achieving precise control of the clamping position of the workpiece, enabling the operator to prevent tapping position deviation caused by workpiece movement or instability according to the actual size and shape of the workpiece, and effectively avoiding the problem of tapping exceeding the required position due to operation fatigue.

[0023] Furthermore, connection holes are provided at both ends of the adjusting plate 806, and springs 805 are arranged inside the connection holes. The connection holes provided at both ends of the adjusting plate provide a stable installation position for the springs, ensuring that the springs can function precisely. The springs can provide a continuous pushing force between the main clamping plate and the pressure plate, ensuring the distance between the pressure plate and the adjusting plate, thereby achieving precise control of the clamping position of the workpiece, enabling the operator to prevent tapping position deviation caused by workpiece movement or instability according to the actual size and shape of the workpiece, and effectively avoiding the problem of tapping exceeding the required position due to operation fatigue.

[0024] Furthermore, a positioning rod 9 is provided in the middle of the slider 4. One end of the positioning rod 9 is fixedly connected to the middle of the fixed bracket 701. Through the positioning rod provided in the middle of the slider, one end of the positioning rod is fixedly connected to the middle of the fixed bracket, ensuring the stability and accuracy of the slider during movement. No matter how the slider moves, the positioning rod always provides a fixed reference point for it, thereby effectively preventing the deviation or shaking of the slider and ensuring that each processing meets the expected accuracy requirements.

[0025] In this solution, the working process is as follows: First, ensure that the base is firmly supported on the horizontal plane, then fix the item to be tapped on the fixture, and then adjust the auxiliary positioning component, tightly press the connecting head in the auxiliary positioning component against the tapping head, and then adjust the positions of the adjusting rod and the adjusting plate according to the tapping requirements. Then, when the motor is started, it directly drives the rotating shaft to rotate at a high speed, which is the power source for the operation of the slider.

[0026] The middle part of the rotating shaft is tightly connected to the slider by a thread. When the rotating shaft rotates, the slider will move precisely linearly along the rotating shaft. This design enables the slider to stop at the exact position where tapping is required, providing accurate positioning for the subsequent tapping operation.

[0027] One side of the slider is equipped with a second motor, which is specifically responsible for driving the tapping head to perform the tapping operation. When the slider moves to the predetermined position, the second motor will start, driving the tapping head to perform precise tapping on the workpiece.

[0028] Next to the tapping head is a specially designed fixture for firmly fixing the workpiece. Inside the fixture, there is an auxiliary positioning component. Through the coordinated action of components such as the connecting head, sliding rod, and pressing plate, this component can ensure that the workpiece remains stable during the tapping process without any movement or deflection.

[0029] The design of the adjusting plate and spring inside the fixture provides the fixture with an adaptive clamping force. The elasticity of the spring and the slidability of the adjusting plate enable the fixture to make fine adjustments according to the sizes and shapes of different workpieces, thus ensuring that each workpiece can be firmly clamped.

[0030] After the tapping head reaches a certain position, the pressing plate tightly presses against one side of the adjusting plate. At this time, the tapping head will continue to rotate but stop tapping, waiting for the staff to perform the next action.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
