Description

Technical Field

[0001] The present application relates to the technical field of drilling and tapping equipment, and in particular to a drilling and tapping equipment for mechanical processing. Background Art

[0002] Drilling and tapping equipment is a metal processing equipment used for drilling and tapping on workpieces. Existing drilling and tapping equipment includes a clamping assembly. During the process of processing the workpiece, the clamping assembly clamps the workpiece, and the drilling assembly drills the positioned workpiece. After the drilling is completed, the tool changer switches the drilling tool to a tapping tool, or an additional independently driven tapping assembly is set to tap the drilled hole to form a threaded hole.

[0003] However, when traditional tapping and drilling equipment is used to drill and tap blind holes in workpieces, debris left over from the drilling process remains in the blind holes formed by drilling. Usually, a blowing component is required to purge the blind holes. However, the airflow formed by the purge mechanism will form a "dead zone" in the blind holes, making it difficult to completely clean the debris in the blind holes. This can easily lead to increased wear of the subsequent tapping tool tapping action and reduced tapping hole accuracy, affecting the service life of the tapping drill bit and the forming quality of the workpiece. Summary of the invention

[0004] The present application proposes a drilling and tapping device for mechanical processing, which has the advantages of improving the chip cleaning effect in the drill hole and improving the workpiece forming quality, and is used to solve the problem that the residual chips in the drilling and forming process are difficult to be completely cleaned by the blowing component.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a drilling and tapping equipment for mechanical processing, comprising a bracket, a drilling assembly and a tapping assembly, characterized in that a rotating disk is rotatably arranged on the inner side of the bracket, a driving motor for driving the rotating disk to rotate is fixedly arranged on the back side of the bracket, a support seat is arranged on the outer side of the rotating disk, a clamping assembly is arranged on the support seat, the number of the support seats is set to be several, and a purge mechanism is arranged at the bottom of the bracket.

[0006] The clamping assembly is used to clamp the workpiece during the rotation, drilling and tapping of the support seat. The rotating disk can rotate relative to the bracket to drive the support seat from the top of the rotating disk to the drilling assembly and then to the tapping assembly, so that the support seat rotates to the bottom of the rotating disk after passing the drilling assembly. When it rotates to the corresponding position of the tapping assembly, the purge mechanism can purge the workpiece corresponding to the support seat that has rotated to the bottom.

[0007] Furthermore, the clamping assembly includes two positioning plates, one side of the positioning plate is fixedly connected to a positioning rod, the outer movable sleeve of the positioning rod is provided with a No. 1 spring, one end of the positioning rod is fixedly connected to a moving block, a permanent magnet is fixedly set inside the moving block, and an electromagnet is fixedly set at the midpoint position on the top of the bracket, and the acting force between the electromagnet and the corresponding permanent magnet is an attractive force and the magnitude of the attractive force is greater than the elastic force of the corresponding No. 1 spring.

[0008] The workpiece is clamped on the support seat by the elastic force of the spring, so that the rotating disk can drive the workpiece on the support seat to rotate, and when the support seat rotates to the top, by adjusting the opening and closing of the electromagnet, the force between the permanent magnet and the electromagnet can drive the positioning plate to move, thereby adjusting the clamping state of the workpiece.

[0012] The No. 2 spring transmission drives the support seat to shrink toward the center of the rotating disk, and the outer wall of the adjusting arc plate drives the support seat away from the center of the rotating disk. The protrusion contacts the adjusting arc plate at different positions during the rotation process, and cooperates with the No. 2 spring to drive the support seat to move back and forth.

[0013] Furthermore, two hydraulic push rods are provided on both sides of the bracket, and the output ends of the hydraulic push rods are fixedly connected with a tightening block.

[0014] Before drilling or tapping the workpiece, the hydraulic push rod drives the clamping block to clamp the moving block to ensure that the positioning plate clamps the workpiece during the workpiece processing.

[0015] Furthermore, the purging mechanism includes a rotating tube, one end of which is fixedly connected to a connecting tube, one end of which is provided with a sliding tube, and one end of which is fixedly connected to a nozzle.

[0016] The air flow ejected from the nozzle is used to purge the blind hole drilled on the workpiece when the blind hole is in a downward tilted state.

[0017] Furthermore, the sliding tube is slidably connected to the connecting tube, the sliding tube is T-shaped, the aperture of the sliding tube is smaller than the aperture of the connecting tube, a baffle is fixedly connected at the midpoint of one side of the nozzle, the width of the baffle is matched with the diameter of the blind hole of the workpiece, a spray hole is opened on the inner side of the nozzle, the spray hole is connected with the sliding tube and is located on one side of the baffle, and a return spring is movably arranged on the outer side of the sliding tube.

[0020] The air flow directions of the air inlet channel and the air exhaust channel formed by the nozzles corresponding to different support seats and the baffles are opposite, so that the blind hole of a single workpiece is purged and cleaned twice in succession.

[0021] Furthermore, the rotating tube is rotatably sleeved with the bracket, a transmission gear is fixedly sleeved on one side of the rotating tube, an adjusting motor is fixedly connected to the front side of the bracket, an output end of the adjusting motor is transmission-connected with a driving gear, the driving gear and the transmission gear are meshed with each other, and the axis of the rotating tube is colinear with the axis of the rotating disk.

[0022] The motor drive is adjusted to drive the connecting pipe to rotate, so that the connecting pipe and the rotating disk rotate at the same angle. During the rotation, the blind hole is purged by blowing out airflow from the nozzle.

[0023] Furthermore, adjusting rods are threadedly sleeved on both sides of the support seat, one end of the adjusting rod is rotatably engaged with a limiting plate, the output end of the driving motor is rotatably connected to a rotating disk via a rotating shaft, and a collecting box is fixedly arranged at the bottom of the bracket.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1, as Figure 1-Figure 6 A drilling and tapping device for mechanical processing, comprising a bracket 1, a rotating disk 2 is rotatably arranged on the inner side of the bracket 1, a support seat 5 is arranged on the outer side of the rotating disk 2, the number of the support seats 5 is set to be several and the several support seats 5 are evenly spaced and arranged in a circular shape on the rotating disk 2, see Figure 2 , both sides of the support seat 5 are threadedly sleeved with an adjusting rod 6, one end of the adjusting rod 6 is rotatably clamped with a limiting plate 7, the bottom end of the limiting plate 7 is in contact with the top surface of the support seat 5, and the limiting plate 7 can only move relative to the support seat 5 in the axial direction of the adjusting rod 6. The front and back sides of the support seat 5 are provided with positioning plates 10, and the positioning plates 10 are in an inverted L shape. The positioning plates 10 cooperate with the limiting plates 7 to position the workpiece 34, see Figure 6 A positioning rod 9 is fixedly connected to one side of the positioning plate 10 , and a spring 13 is movablely sleeved on the outer side of the positioning rod 9 .

[0030] The first spring 13 is used to drive the two positioning plates 10 to approach the workpiece 34 to clamp the workpiece 34. The positioning rod 9 is slidably sleeved with the support seat 5. One end of the positioning rod 9 is fixedly connected to the moving block 8. The interior of the moving block 8 is fixedly provided with a permanent magnet 11. Figure 2 An electromagnet 12 is fixedly provided at the midpoint position of the top of the bracket 1, and the positions of the two moving blocks 8 located at the top of the rotating disk 2 correspond to the positions of the electromagnet 12 respectively. It also includes a drilling component 3 for drilling a workpiece 34 and a tapping component 4 for tapping the workpiece 34 on the basis of drilling. The drilling component 3 and the tapping component 4 are respectively located on both sides of the bracket 1. The unidirectional rotation direction of the rotating disk 2 is from the position of the electromagnet 12 to the drilling component 3 and then to the corresponding position of the tapping component 4. The acting force between the electromagnet 12 and the corresponding permanent magnet 11 is an attractive force, and the attractive force is greater than the elastic force of the corresponding No. 1 spring 13. A driving motor 33 is fixedly provided on the back of the bracket 1, and the output end of the driving motor 33 is rotatably connected to the rotating disk 2 through a rotating shaft.

[0031] The adjusting rod 6 is rotated in advance to drive the limit plate 7 to move, and the distance between the two limit plates 7 is adjusted to match the specifications of the workpiece 34. When in use, the electromagnet 12 is started, and the electromagnet 12 cooperates with the corresponding permanent magnet 11 rotated to the top of the rotating disk 2 to drive the moving block 8, and the moving block 8 drives the corresponding positioning rod 9 to move, and the positioning rod 9 drives the positioning plate 10 to move, so that the two positioning plates 10 move to remove the clamping of the tapped workpiece 34, and the tapped workpiece 34 is unloaded through the linear clamping component of the drilling and tapping equipment, and the workpiece 34 to be processed is clamped and placed on the support seat 5, or the workpiece 34 is manually loaded and unloaded. Two hydraulic push rods 14 are arranged on both sides of the bracket 1. The two hydraulic push rods 14 on one side of the bracket 1 are respectively located on the front and back sides of the bracket 1 and correspond to the positions of the moving block 8 respectively, and the output end of the hydraulic push rod 14 is fixedly connected with a tightening block 15.

[0032] After the loading is completed, the electromagnet 12 is turned off, and the No. 1 spring 13 is reset to drive the positioning plate 10 to clamp the workpiece 34 to be drilled. The driving motor 33 is started to drive the rotating disk 2 to rotate the rated angle. The rotation of the rotating disk 2 drives the support seat 5 to rotate, so that the workpiece 34 at the tapping assembly 4 moves to the top of the rotating disk 2, and the support seat 5 corresponding to the workpiece 34 to be drilled moves to the corresponding position of the drilling assembly 3. The support seat 5 between the drilling assembly 3 and the tapping assembly 4 moves along the rotation direction of the rotating disk 2, so that the support seat 5 corresponding to the single workpiece 34 to be tapped moves to the corresponding position of the tapping assembly 4. After the rotation of the rotating disk 2 is completed, the hydraulic push rod 14 drives the clamping block 15 to move and clamp the moving block 8. In the subsequent drilling and tapping process, it is ensured that the positioning plate 10 has sufficient clamping force on the workpiece 34, and the drilling assembly 3 and the tapping assembly 4 respectively drill and tap the workpiece 34 at the corresponding position.

[0033] A rotating tube 18 is provided on the front of the bracket 1, one end of which is fixedly connected to a connecting tube 19, the rotating tube 18 is connected to the air supply assembly through a pipeline, the connecting tube 19 is U-shaped and one end of the connecting tube 19 is provided with a sliding tube 20, one end of the sliding tube 20 is fixedly connected to a nozzle 21, the position of the nozzle 21 corresponds to the position of the drill hole on the workpiece 34, the nozzle 21 is located at the bottom of the rotating disk 2, and a collecting box 23 is fixedly provided at the bottom of the bracket 1, and the support seat 5 drives the workpiece 34 to move to the rotating disk 2. When the disk 2 is at the bottom position, gas is introduced into the rotating tube 18, and the gas is ejected from the nozzle 21 after passing through the connecting tube 19 and the sliding tube 20. When the drilling hole is in the state of opening downward, air flow blowing is performed, so that the debris in the blind hole drilling is blown out of the blind hole under the combined action of gravity and air flow, and enters the collection box 23 for collection, thereby improving the cleaning effect of the debris in the blind hole, avoiding additional wear of the tapping tool during the subsequent tapping of the blind hole, extending the service life of the tapping tool, and improving the tapping forming quality of the subsequent blind hole.

[0034] Embodiment 2, as Figure 1-Figure 3 , Figure 5 and Figure 7 On the basis of the first embodiment, the bottom of the bracket 1 is fixedly connected with an adjusting arc plate 16, see Figure 2 A protrusion 17 is fixedly connected to the middle of the top of the support seat 5, and the bottom surface of the protrusion 17 is an arc-shaped surface, see Figure 7 A sliding rod 25 is fixedly connected to the bottom of the support seat 5, and a fixed cylinder 24 is slidably sleeved on the outer side of the sliding rod 25. The fixed cylinder 24 is fixedly sleeved with the rotating disk 2. The rotation of the rotating disk 2 drives the fixed cylinder 24 to rotate. The rotation of the fixed cylinder 24 drives the sliding rod 25 to rotate. The sliding rod 25 drives the support seat 5 to rotate. The sliding rod 25 is T-shaped. The sliding rod 25 can slide relative to the fixed cylinder 24 without separating from the fixed cylinder 24.

[0035] A guide rod 28 is fixedly connected to the top of the support seat 5. A guide groove 27 is provided on one side of the fixed cylinder 24. The guide rod 28 is slidably sleeved in the guide groove 27. The guide groove 27 cooperates with the guide rod 28 to limit the rotation of the support seat 5 relative to the fixed cylinder 24 without affecting the sliding rod 25 relative to the fixed cylinder 24. A second spring 26 is movably sleeved in the fixed cylinder 24. One end of the second spring 26 abuts against the end with a larger diameter of the sliding rod 25 to push the sliding rod 25 to retract into the fixed cylinder 24. See Figure 3 , the outer wall of the adjustment arc plate 16 is wavy.

[0036] When the rotating disk 2 drives the support seat 5 to rotate to a position close to the bottom of the rotating disk 2, with the blind hole opening of the workpiece 34 facing downward, the outer wall of the adjusting arc plate 16 abuts against the protrusion 17. As the support seat 5 rotates relative to the adjusting arc plate 16, the outer wall of the adjusting arc plate 16 pushes the protrusion 17 and then drives the support seat 5 to move, the No. 2 spring 26 resets and cooperates with the sliding rod 25 to drive the support seat 5 to move alternately, so that the support seat 5 rotates and reciprocates in the radial direction of the rotating disk 2, and then the workpiece 34 reciprocates in the axial direction of the blind hole when facing the blind hole, so that the debris in the blind hole can be more easily separated from the blind hole under the action of gravity, further improving the cleaning effect and efficiency of the blind hole.

[0037] Embodiment three, as Figure 1 , Figure 3 , Figure 5 and Figure 6On the basis of the second embodiment, the sliding tube 20 is slidably connected with the connecting tube 19, and the sliding tube 20 is T-shaped. A reset spring 35 is movably arranged on the outer side of the sliding tube 20, which is used to drive the sliding tube 20 to reset after the air supply is stopped. The sliding tube 20 can slide in the axial direction of the connecting tube 19 without being separated from the connecting tube 19. The aperture size of the sliding tube 20 is smaller than the aperture size of the connecting tube 19. A baffle 22 is fixedly connected at the midpoint position of one side of the nozzle 21. The width of the baffle 22 is adapted to the diameter of the blind hole of the workpiece 34. A spray hole 29 is provided on the inner side of the nozzle 21. The spray hole 29 is connected to the sliding tube 20 and is located on one side of the baffle 22. The number of connecting tubes 19 is set to two, and the two connecting tubes 19 correspond to the two support seats 5 respectively.

[0038] After the rotating disk 2 rotates the rated angle, gas is introduced into the connecting pipe 19. When the airflow enters the sliding pipe 20, it drives the sliding pipe 20 to extend out of the connecting pipe 19, so that the nozzle 21 is close to the blind hole, and the nozzle 21 drives the baffle 22 to extend into the blind hole of the workpiece 34. The distance that the baffle 22 extends into the blind hole is less than the opening depth of the blind hole. The blind hole is separated by the opening part by the baffle 22 to form an intake channel and an exhaust channel. The nozzle holes 29 of the nozzles 21 corresponding to the two connecting pipes 19 correspond to different sides of the baffle 22, respectively, so that the airflow directions of the intake channel and the exhaust channel formed by the two nozzles 21 and the corresponding baffle 22 are opposite, thereby forming a lateral airflow at the bottom of the blind hole, reducing the "dead zone" of the airflow in the blind hole, and reducing the debris at the outlet of the blind hole driven by the airflow to be blown back into the blind hole, thereby further improving the purging and cleaning effect of the debris in the blind hole.

[0039] Embodiment 4, as Figure 1 , Figure 3-Figure 6 On the basis of the third embodiment, the rotating tube 18 is rotatably sleeved with the bracket 1, and a transmission gear 30 is fixedly sleeved on one side of the rotating tube 18. The front side of the bracket 1 is fixedly connected with an adjusting motor 31. The output end of the adjusting motor 31 is transmission-connected with a driving gear 32. The driving gear 32 and the transmission gear 30 are meshed with each other. When the rotating disk 2 rotates, the adjusting motor 31 is synchronously started to drive the driving gear 32 to rotate. The driving gear 32 rotates to drive the transmission gear 30 to rotate. The transmission gear 30 drives the rotating tube 18 to rotate. The axis of the rotating tube 18 is colinear with the axis of the rotating disk 2. The rotating tube 18 drives the connecting tube 19 to rotate. The connecting tube 19 and the rotating disk 2 rotate synchronously at the same angular velocity, so that the workpiece 34 moves back and forth while the nozzle 21 cooperates with the baffle 22 to perform a purge. After the purge is completed, the purge is stopped, the connecting sliding tube 20 is reset, and the motor drives the connecting tube 19 to reset.

[0040] The baffle 22 moves relative to the workpiece 34 in the axial direction of the blind hole, so that the spacing between the bottom of the blind hole of the workpiece 34 and the baffle 22 changes alternately, so that the opening size of the connecting part of the conduction channel and the exhaust channel separated by the baffle 22 changes alternately, thereby making it easier to form air flow turbulence, further reducing the possibility of "dead zone" in the air flow flow channel, and further improving the cleaning effect of debris. In addition, the baffle 22 contacts the bottom of the blind hole, and the workpiece 34 reciprocates to cooperate with the nozzle 21 to drive the baffle 22 to move intermittently, reducing the possibility of debris adhering to the baffle 22, avoiding cross-contamination of debris that may remain in the baffle 22, and further improving the reliability of the drilling and tapping equipment.

[0041] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
