[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: in the tapping process of modern steel sleeves, sometimes for application requirements, it is necessary to perform positive tapping and reverse tapping on both ends of the steel sleeves. At present, positive tapping and reverse tapping are usually processed in two passes, so the materials need to be re-stacked and positioned, and the step processing steps are cumbersome and easily cause insufficient concentricity of positive tapping and reverse tapping. Therefore, the application discloses a tapping device for steel sleeves, which adopts the method of synchronous positive and reverse tapping. The specific equipment uses a processing table 1 as a support, and a feeding track is arranged on the processing table 1. The feeding track is used to feed the step positioner 2. The step positioner 2 steps the material through the processing station. A pair of control slide rails 3 are arranged on both sides of the step positioner 2 on the processing table 1. A pair of positive and reverse tapping devices are arranged on the pair of control slide rails 3 to perform positive tapping and reverse tapping respectively.

[0021] According to the instruction manual Figure 1-2 It can be known that the central axes of the pair of control rails 3 are parallel and staggered at least one station and a pair of sliding support seats 4 are installed on the pair of control rails 3. The pair of control rails 3 play a limiting role on the pair of sliding support seats 4. By synchronously controlling the relative movement of the pair of sliding support seats 4, the pair of tapping devices can be synchronously fed.

[0022] In the specific implementation process, a fixed frame 5 is arranged on the sliding support seat 4, and a control motor 6 is installed on the fixed frame 5. The fixed frame 5 is used to support the control motor 6. A transmission housing 7 is connected to the driving end of the control motor 6. A transmission device is arranged in the transmission housing 7. Specifically, gear transmission, sprocket transmission or pulley transmission can be used to make the control motor 6 drive the rotating flywheel 8 to rotate. A tapping spindle 9 is coaxially installed on the rotating flywheel 8. The head end of the tapping spindle 9 is connected to a tapping mounting seat 10. The tapping spindle 9 is driven to rotate by rotating the flywheel 8, and then the tapping spindle 9 drives the tapping mounting seat 10 rotates, and the tapping mounting seat 10 is used to install the tapping drill bit, wherein the above-mentioned tapping mounting seats 10 of the two sliding support seats 4 are respectively installed with a forward tapping drill bit 11 and a reverse tapping drill bit 12, which is convenient for forward tapping and reverse tapping of the workpiece, and the axes of the forward tapping drill bit 11 and the reverse tapping drill bit 12 are staggered at least one workstation. First, the material is forward tapped under the action of the stepping positioner 2, and when the forward tapping is completed, it moves to the next workstation under the push of the subsequent material, and the stepping positioner 2 is fixed before reverse tapping is performed, and finally the stepping material is unloaded, so that the forward and reverse tapping can be completed synchronously.

[0023] As a preferred solution, further, a tapping cooling water supply pipe 13 is connected to the positioner for cooling the tapping drill bit.

[0024] As a preferred solution, further, a pair of tapping sleeves 14 are respectively installed on the pair of sliding support seats 4, and the tapping sleeves 14 are sleeved outside the tapping spindle 9 to limit the tapping spindle 9.

[0025] As a preferred solution, further, the rotating flywheel 8 and the driving end of the control motor 6 are driven by a sprocket.

[0026] As a preferred solution, further, according to the attached description Figure 1-3 It can be known that the above-mentioned stepping positioner 2 includes a support frame 201, which is welded on the processing table 1 and connected to the end of the feeding track. A sliding groove 202 is provided on the support frame 201 on the axial plane of the positive tapping drill bit 11 and the reverse tapping drill bit 12, and a pair of tapping through holes 203 are provided on both sides of the sliding groove 202, and the pair of tapping through holes 203 correspond to the positive tapping drill bit 11 and the reverse tapping drill bit 12 respectively. A clamping positioning plate 204 is arranged on the sliding groove 202, and a plurality of wavy clamping grooves are provided on the bottom surface of the clamping positioning plate 204. A control cylinder 205 is connected to the top of the support frame 201, and the telescopic end of the control cylinder 205 is connected to the clamping positioning plate 204;

[0027] In the specific implementation process, the stepper positioner 2 is used to step and convey materials. The stepper positioner 2 uses a support frame 201 as a processing support shell. The end of the sliding groove 202 on it is connected to the feeding track. Due to the conveying effect of the conveying track, the material is pushed into the sliding groove 202. A pair of tapping holes 203 are arranged on the sliding groove 202, corresponding to the positive tapping drill bit 11 and the reverse tapping drill bit 12 respectively. The pair of tapping holes 203 are arranged in a staggered station. The workpiece first passes through the tapping corresponding to the positive tapping drill bit 11. The sliding support seat 4 mobilizes the forward tapping drill bit 11 to insert into the tapping hole 203 to perform forward tapping on the corresponding workpiece, and then controls the cylinder 205 to loosen the clamping positioning plate 204. Under the pushing action of the external material, the workpiece enters the tapping hole 203 of the corresponding reverse tapping drill bit 12 to complete the reverse tapping process. It should be pointed out that during operation, since the material is arranged in one direction in the sliding groove 202, the forward tapping drill bit 11 and the reverse tapping drill bit 12 move synchronously, and the two only need to be staggered in space.

[0028] As a preferred solution, further, the wavy clamping grooves on the clamping positioning plate 204 match the outer arc surface of the cylindrical pipe, and a loading clamping plate 206 is connected to the end of the clamping positioning plate 204. The loading clamping plate 206 is blocked at the end of the sliding groove 202. When the loading clamping plate 206 is pressed down, the end of the sliding groove 202 is blocked to avoid the problem of instability caused by the external material pushing the internal material during processing. The sliding groove 202 is provided with a discharge port 207 at one end corresponding to the loading clamping plate 206, and the material is automatically discharged after stepping into the discharge port 207.

[0029] From the above, it can be generally known that the steel bar sleeve tapping device has a step positioner 2 with a step feeding function arranged in the middle of the table top. The step positioner 2 limits the material while stepping the material. A pair of tapping devices are staggered on both sides of the stepping conveying station of the material. The pair of tapping devices move synchronously to perform forward and reverse thread processing on the workpiece, which effectively increases the processing efficiency when performing forward and reverse tapping on the same workpiece, and is more convenient for positioning and processing.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
