Description

Technical Field

[0001] The invention belongs to the technical field of plastic part tapping, in particular to a plastic part tapping machine and a process thereof. Background Art

[0002] Plastic tapping refers to the process of using a drill to drill small holes in plastic parts. Among them, tapping is a common processing method used to drill threaded holes in plastic parts to facilitate the installation of screws or other fasteners. The tapping process requires the use of specialized tools and equipment, such as drills, tapping machines, etc.

[0003] The chips of plastic parts are easily filled on the tap. When the tap is reversed, even if the chips on the tap are removed in time, some chips will still remain on the inner surface of the plastic workpiece. The presence of these chips can easily cause the tap to stick and become stuck, thus affecting the accuracy of the internal thread processing of the plastic part. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention solves the technical problems by adopting a technical solution: a plastic tapping machine, comprising: a base, the top of the base is rotatably connected to a driving shaft, the outer wall of the driving shaft is fixedly connected to a turntable, and the outer wall of the base is fixedly connected to a bracket;

[0005] The plastic tapping machine also includes:

[0006] A drilling mechanism, the top of which is fixedly connected to the inner wall of the bracket;

[0007] The drilling mechanism includes a driving seat, the top of the driving seat is fixedly connected to the inner wall of the bracket, the bottom of the driving seat is rotatably connected to a tapping assembly, the bottom of the driving seat is fixedly connected to a positioning assembly, the inner wall of the positioning assembly is socketed with the outer wall of the tapping assembly, the bottom of the positioning assembly is fixedly connected to a connecting rod, and the bottom of the connecting rod is fixedly connected to a cleaning assembly, so that the generated debris and dust are affected by the airflow and diffused around the plastic plate, and finally enter the collecting assembly. With the assistance of the positioning assembly, after the tapping assembly is drilled in the plastic plate, it is rotated in the opposite direction of the original path and pulled out, and the axis of the tapping assembly is kept unchanged during the withdrawal. In the process of the tapping assembly moving away from the plastic plate, the cleaning assembly gradually approaches the tapping assembly to clean its surface and gaps.

[0008] Furthermore, fixing mechanisms are evenly arranged on the surface of the turntable, air suction holes are evenly opened on one side of the top of the turntable close to the fixing mechanism, and the bottom of the fixing mechanism is fixedly connected to the top of the turntable.

[0009] Furthermore, the fixing mechanism includes a fixing seat, the bottom of the fixing seat is fixedly connected to the top of the turntable, and moving blocks are evenly arranged on the top of the fixing seat, and the bottom of the moving block is slidably connected to the top of the fixing seat. The outer wall of the moving block is rotatably connected to a bent rod, and the end of the bent rod away from the moving block is fixedly connected to an M plate, and the outer wall of the M plate is fixedly connected to a collecting bucket, and the inner wall of the collecting bucket is in contact with the outer wall of the bent rod. A plastic plate is arranged at the central axis of the top of the fixing seat, and the bottom of the M plate is in contact with the top of the plastic plate. The rotation of the bent rod drives the M plate to be placed on the top of the plastic plate, so that the collecting bucket is close to the drilling position, thereby facilitating the blocking and collection of debris and dust generated during the drilling process, and maintaining the stability of the plastic plate during the drilling process.

[0010] Further, the positioning assembly includes a sleeve, the top of the sleeve is fixedly connected to the bottom of the driving seat, the interior of the sleeve is socketed with the outer wall of the tapping assembly, the inner wall of the sleeve is evenly provided with a telescopic rod, the top of the telescopic rod is fixedly connected to the bottom of the driving seat, the bottom of the telescopic rod is fixedly connected with a mounting ring, the outer wall of the mounting ring is socketed with the inner wall of the sleeve, the bottom of the mounting ring is fixedly connected to the top of the connecting rod, the outer wall of the connecting rod is socketed with the inner wall of the sleeve, the bottom of the sleeve is evenly provided with a telescopic column, the top of the telescopic column is fixedly connected to the bottom of the sleeve, the bottom of the telescopic column is fixedly connected with a fixing sleeve, the inner wall of the fixing sleeve is provided with an inclined surface, the telescopic column moves with the tapping assembly to move the fixing sleeve downward, the inclined surface arranged inside the fixing sleeve causes the airflow direction blown out of the tapping assembly to change downward, thereby causing the generated debris and dust to be blown away, and the auxiliary cleaning assembly maintains stability on the tapping assembly.

[0011] Furthermore, the tapping assembly includes a hydraulic rod, the top of the hydraulic rod is rotatably connected to the bottom of the driving seat, the bottom of the hydraulic rod is fixedly connected to a tube body, the bottom of the tube body is fixedly connected to a tapping head, and air outlet holes are evenly opened on the outer wall of the tube body close to the tapping head, so that gas is ejected from the air outlet holes. Under the action of the fixed sleeve, the airflow comes into contact with the debris generated by tapping, and the debris is cut off and quickly discharged by the strong airflow, thereby reducing the accumulation of debris.

[0012] Furthermore, the cleaning assembly includes a fixing ring, the outer wall of the fixing ring is fixedly connected to the bottom of the connecting rod, the inner wall of the fixing ring is symmetrically provided with an elastic rod, the outer wall of the elastic rod is slidably connected to the inner wall of the fixing ring, the outer wall of the fixing ring is symmetrically provided with a fixing tube, the outer wall of the fixing tube is fixedly connected to the outer wall of the fixing ring, the top of the elastic rod is fixedly connected to a counterweight block, the end of the elastic rod away from the counterweight block is fixedly connected to a cleaning block, and the outer wall of the cleaning block is symmetrically provided with serrated protrusions, the elastic rod moves along the fixing ring and the interior of the fixing tube in a direction close to the tapping head, so that the surface of the cleaning block contacts the tapping head, and since two serrated protrusions are provided at one end of the cleaning block close to the tapping head, the serrated protrusion and the gap of the tapping head are more closely fitted, thereby cleaning the gap inside the tapping head during the reverse rotation of the tapping head, and keeping the tapping head clean before the next tapping.

[0013] A process for a plastic part tapping machine comprises the following steps:

[0014] S1: The worker places the circular plastic plate in the fixed seat one by one, sucks air through the air suction hole, fixes the plastic plate with the moving block, and then the turntable drives the plastic plate to rotate to the bottom of the drilling mechanism;

[0015] S2: The driving seat drives the positioning assembly to move downward, so that the positioning assembly contacts the top of the plastic plate, and in the process of the driving seat driving the tapping assembly to move downward, the cleaning assembly is pressed away from the tapping assembly, and then the tapping and drilling are performed;

[0016] S3: During the tapping process, the tapping assembly blows air to the processing area so that the debris generated during tapping is blown into the collection bucket. After the tapping is completed, the tapping head is taken out by rotating in the reverse direction and moved upward, so that the cleaning assembly is close to the tapping head for cleaning;

[0017] S4: The turntable keeps rotating in one direction, making the plastic plate processing process smoother. After the tapping is completed, the worker takes out the processed workpiece.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The chips of plastic parts are easily filled on the tap. When the tap is reversed, even if the chips on the tap are removed in time, some chips will still remain on the inner surface of the plastic workpiece. The present invention provides a drilling mechanism, blows air outward during the working process of the tapping assembly, and the positioning assembly keeps the airflow downward, so that the generated debris and dust are affected by the airflow and diffused around the plastic plate, and finally enter the collecting assembly. With the assistance of the positioning assembly, after the tapping assembly completes drilling in the plastic plate, it is rotated and pulled out in the opposite direction of the original path, and the axis of the tapping assembly is kept unchanged during the pulling out. In the process of the tapping assembly moving away from the plastic plate, the cleaning assembly gradually approaches the tapping assembly to clean its surface and gaps.

[0020] 2. The present invention sets a fixing mechanism, and the negative pressure generated by suction enables the plastic plate to be stably placed on the fixing seat. When drilling, the bending rod rotates to drive the M plate to be placed on the top of the plastic plate, so that the collecting bucket is close to the drilling position, thereby facilitating the blocking and collection of debris and dust generated during the drilling process, thereby maintaining the stability of the plastic plate during the drilling process.

[0021] 3. The present invention sets a positioning component so that the cleaning component is away from the tapping component, and then starts tapping. The telescopic rod contracts during the downward movement of the tapping component, but keeps the position of the mounting ring unchanged. The telescopic column moves with the tapping component to move the fixing sleeve downward. The inclined surface set inside the fixing sleeve changes the direction of the airflow blown out of the tapping component downward, thereby blowing away the generated debris and dust, and the auxiliary cleaning component keeps the tapping component stable.

[0022] 4. The present invention sets a cleaning assembly. Under the action of the gravity of the counterweight block itself, the elastic rod moves along the inside of the fixing ring and the fixing tube toward the tapping head, so that the surface of the cleaning block contacts the tapping head. Since two serrated protrusions are set at one end of the cleaning block close to the tapping head, the serrated protrusions and the gap of the tapping head are more closely fitted, so that the gap inside the tapping head is cleaned during the reverse rotation of the tapping head, and the tapping head is kept clean before the next tapping.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0034] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a plastic tapping machine and its process are described as follows.

[0035] It comprises: a base 1, the top of the base 1 is rotatably connected to a driving shaft 6, the outer wall of the driving shaft 6 is fixedly connected to a turntable 2, and the outer wall of the base 1 is fixedly connected to a bracket 3;

[0036] The plastic tapping machine also includes:

[0037] A drilling mechanism 4, the top of which is fixedly connected to the inner wall of the bracket 3;

[0038] The surface of the turntable 2 is evenly provided with fixing mechanisms 5 , and the top of the turntable 2 near the fixing mechanisms 5 is evenly provided with air suction holes 7 , and the bottom of the fixing mechanisms 5 is fixedly connected to the top of the turntable 2 .

[0039] During work, the worker places the plastic plate 503 to be processed on the turntable 2, fixes the plastic plate 503 by sucking air through the suction hole 7, fixes the circular plastic plate 503 by the fixing mechanism 5, and then drives the turntable 2 to rotate by the driving shaft 6 to move the plastic part to the bottom of the drilling mechanism 4, and then the drilling mechanism 4 taps the plastic plate 503 downwards. The debris generated during the tapping process will be blown outward by the drilling mechanism 4, and the debris will be collected by the fixing mechanism 5.

[0040] The fixing mechanism 5 includes a fixing seat 501, the top of which is provided with a hole corresponding to the position of the air suction hole 7, the bottom of the fixing seat 501 is fixedly connected to the top of the turntable 2, the top of the fixing seat 501 is evenly provided with moving blocks 502, the bottom of the moving blocks 502 is slidably connected to the top of the fixing seat 501, the outer wall of the moving block 502 is rotatably connected to a bending rod 504, the end of the bending rod 504 away from the moving block 502 is fixedly connected to an M-plate 505, the outer wall of the M-plate 505 is fixedly connected to a collecting bucket 506, the collecting bucket 506 is made of a flexible material, the inner wall of the collecting bucket 506 is in contact with the outer wall of the bending rod 504, a plastic plate 503 is provided at the central axis of the top of the fixing seat 501, and the bottom of the M-plate 505 is in contact with the top of the plastic plate 503.

[0041] The circular plastic plate 503 is placed on the fixed seat 501, and the four groups of movable blocks 502 are close to each other so that the plastic plate 503 is clamped in the middle of the fixed seat 501. At this time, the plastic plate 503 blocks the air suction hole 7, and the negative pressure generated by the suction enables the plastic plate 503 to be stably placed on the fixed seat 501. When drilling, the bending rod 504 rotates to drive the M plate 505 to be placed on the top of the plastic plate 503, so that the collecting bucket 506 is close to the drilling position, thereby facilitating the blocking and collection of the debris and dust generated during the drilling process, and maintaining the stability of the plastic plate 503 during the drilling process.

[0042] The drilling mechanism 4 includes a driving seat 401, the top of the driving seat 401 is fixedly connected to the inner wall of the bracket 3, the bottom of the driving seat 401 is rotatably connected to a tapping assembly 404, the bottom of the driving seat 401 is fixedly connected to a positioning assembly 402, the inner wall of the positioning assembly 402 is socketed with the outer wall of the tapping assembly 404, the bottom of the positioning assembly 402 is fixedly connected to a connecting rod 403, and the bottom of the connecting rod 403 is fixedly connected to a cleaning assembly 405.

[0043] After the plastic plate 503 is moved to the position directly below the drilling mechanism 4, the driving seat 401 drives the tapping assembly 404 to move downward, so that the bottom of the cleaning assembly 405 contacts the top of the plastic plate 503, so that the cleaning assembly 405 can be away from the tapping assembly 404. During the operation of the tapping assembly 404, air is blown outward, and the positioning assembly 402 keeps the airflow downward, so that the generated debris and dust are affected by the airflow and diffused around the plastic plate 503, and finally enter the collecting assembly. With the assistance of the positioning assembly 402, after the tapping assembly 404 completes the drilling in the plastic plate 503, it is pulled out by rotating in the opposite direction of the original path, and the axis of the tapping assembly 404 is kept unchanged during the pulling out. In the process of the tapping assembly 404 moving away from the plastic plate 503, the cleaning assembly 405 gradually approaches the tapping assembly 404 to clean its surface and gaps.

[0044] Example 2, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of embodiment 1, the positioning assembly 402 includes a sleeve 4021, the top of the sleeve 4021 is fixedly connected to the bottom of the driving seat 401, the inside of the sleeve 4021 is sleeved with the outer wall of the tapping assembly 404, the inner wall of the sleeve 4021 is evenly provided with telescopic rods 4022, the top of the telescopic rod 4022 is fixedly connected to the bottom of the driving seat 401, and the bottom of the telescopic rod 4022 is fixedly connected with a mounting ring 4023, and the mounting ring 4023 is installed. The outer wall of the ring 4023 is sleeved with the inner wall of the sleeve 4021, the bottom of the mounting ring 4023 is fixedly connected to the top of the connecting rod 403, the outer wall of the connecting rod 403 is sleeved with the inner wall of the sleeve 4021, the bottom of the sleeve 4021 is evenly provided with telescopic columns 4024, the top of the telescopic columns 4024 is fixedly connected to the bottom of the sleeve 4021, the bottom of the telescopic columns 4024 is fixedly connected with a fixing sleeve 4025, and the inner wall of the fixing sleeve 4025 is provided with an inclined surface 4026.

[0045] Before tapping, the telescopic rod 4022 moves downward, driving the connecting rod 403 at the bottom of the mounting ring 4023 downward, so that the cleaning component 405 first contacts the top of the plastic plate 503 and presses downward, thereby moving the cleaning component 405 away from the tapping component 404, and then tapping begins. The telescopic rod 4022 contracts during the downward movement of the tapping component 404, but keeps the position of the mounting ring 4023 unchanged. The telescopic column 4024 moves with the tapping component 404, so that the fixing sleeve 4025 moves downward. The inclined surface 4026 set inside the fixing sleeve 4025 changes the direction of the airflow blown out of the tapping component 404 downward, thereby blowing away the generated debris and dust, and assisting the cleaning component 405 to keep the tapping component 404 stable.

[0046] The tapping assembly 404 includes a hydraulic rod 4041, the top of which is rotatably connected to the bottom of the driving seat 401, the bottom of the hydraulic rod 4041 is fixedly connected to a tube body 4042, the bottom of the tube body 4042 is fixedly connected to a tapping head 4044, and air outlet holes 4043 are evenly opened on one side of the outer wall of the tube body 4042 close to the tapping head 4044.

[0047] During operation, the hydraulic rod 4041 drives the tapping head 4044 at the bottom of the tube body 4042 downward to drill and tap the plastic plate 503. The tube body 4042 is externally connected to an air pump, and air flow is input during the tapping process to cause the gas to be ejected from the air outlet 4043. Under the action of the fixed sleeve 4025, the air flow comes into contact with the debris generated by the tapping, and the debris is cut off and quickly discharged through the strong air flow, thereby reducing the accumulation of debris.

[0048] The cleaning assembly 405 includes a fixing ring 4051, the outer wall of the fixing ring 4051 is fixedly connected to the bottom of the connecting rod 403, the inner wall of the fixing ring 4051 is symmetrically provided with elastic rods 4053, the elastic rods 4053 can be bent but cannot be stretched, the outer wall of the elastic rods 4053 is slidably connected to the inner wall of the fixing ring 4051, the outer wall of the fixing ring 4051 is symmetrically provided with fixing tubes 4052, the outer wall of the fixing tubes 4052 is fixedly connected to the outer wall of the fixing ring 4051, the top of the elastic rod 4053 is fixedly connected to a counterweight block 4056, the end of the elastic rod 4053 away from the counterweight block 4056 is fixedly connected to a cleaning block 4054, and the outer wall of the cleaning block 4054 is symmetrically provided with serrated protrusions 4055.

[0049] When the connecting rod 403 moves downward, the bottom of the counterweight block 4056 first contacts the top of the plastic plate 503 and continues to move, so that the top of the counterweight block 4056 drives the elastic rod 4053 to be pulled out upward, and the elastic rod 4053 moves along the inner wall of the fixing ring 4051 and the fixing tube 4052. At this time, the end of the elastic rod 4053 close to the counterweight block 4056 is pulled out of the fixing ring 4051, so that the cleaning block 4054 is away from the tapping head 4044. After the tapping is completed, the counterweight block 4056 is lifted up during the upward movement of the tapping head 4044. Under the action of its own gravity, the elastic rod 4053 moves along the inside of the fixing ring 4051 and the fixing tube 4052 toward the tapping head 4044, so that the surface of the cleaning block 4054 contacts the tapping head 4044. Since two serrated protrusions 4055 are provided at one end of the cleaning block 4054 close to the tapping head 4044, the serrated protrusions 4055 and the gap between the tapping head 4044 fit more closely, thereby cleaning the internal gap of the tapping head 4044 during the reverse rotation, and keeping the tapping head 4044 clean before the next tapping.

[0050] A process for a plastic part tapping machine comprises the following steps:

[0051] S1: The worker places the circular plastic plate 503 in the fixing seat 501 in sequence, and the air suction hole 7 sucks air, and the plastic plate 503 is fixed with the moving block 502, and then the turntable 2 drives the plastic plate 503 to rotate to the bottom of the drilling mechanism 4;

[0052] S2: The driving seat 401 drives the positioning assembly 402 to move downward, so that the positioning assembly 402 contacts the top of the plastic plate 503, and in the process of the driving seat 401 driving the tapping assembly 404 to move downward, the cleaning assembly is pressed away from the tapping assembly 404, and then the tapping and drilling are performed;

[0053] S3: During the tapping process, the tapping assembly 404 blows air to the processing area, so that the debris generated during the tapping is blown into the collection bucket 506. After the tapping is completed, the tapping head 4044 is taken out by reverse rotation and moved upward, so that the cleaning assembly is close to the tapping head 4044 for cleaning;

[0054] S4: The turntable 2 keeps rotating in one direction, so that the processing of the plastic plate 503 is smoother. After the tapping is completed, the worker takes out the processed workpiece.

[0055] The specific workflow is as follows:

[0056] When working, the worker places the circular plastic plate 503 on the fixed seat 501, and the four groups of moving blocks 502 are close to each other, so that the plastic plate 503 is clamped in the middle of the fixed seat 501. At this time, the plastic plate 503 blocks the air suction hole 7, and the negative pressure generated by the suction enables the plastic plate 503 to be stably placed on the fixed seat 501. When drilling, the bending rod 504 rotates to drive the M plate 505 to be placed on the top of the plastic plate 503, so that the collecting bucket 506 is close to the drilling position, and then the driving shaft 6 drives the turntable 2 to rotate, so that the plastic part moves to the bottom of the drilling mechanism 4, and the driving seat 401 drives the tapping assembly 404 moves downward so that the bottom of the cleaning component 405 contacts the top of the plastic plate 503, so that the cleaning component 405 can be away from the tapping component 404. During the operation of the tapping component 404, air is blown outward, and the positioning component 402 keeps the airflow downward, so that the generated debris and dust are affected by the airflow and diffused around the plastic plate 503, and finally enter the collecting component. With the assistance of the positioning component 402, after the tapping component 404 completes the drilling in the plastic plate 503, it is rotated and pulled out in the opposite direction of the original path. The debris generated during the tapping process will be blown outward by the drilling mechanism 4, and the debris will be collected by the fixing mechanism 5.
