Description

Technical Field

[0001] The invention relates to the technical field of component turning and milling processing, in particular to a high-efficiency turning and milling processing device for a round bar end and a processing method thereof. Background Art

[0002] Under certain processing requirements, it is necessary to perform milling processing on the end of the round bar. For example, the mortise and tenon structure of chopsticks disclosed in the authorization announcement number CN220757127U requires milling processing for processing the connection between the chopstick head and the chopstick handle. When processing the end of this type of round bar, the conventional means is to clamp the round bar on a clamping fixture by manual or mechanical hands, clamp the corresponding milling cutter tool on the rotating spindle on the multi-axis CNC machine tool, and make the high-speed rotating milling cutter tool contact the milling part of the round bar body through the multi-axis movement of the rotating spindle to perform milling processing on the end of the round bar. This method has low work efficiency because the clamping fixture can generally only clamp one round bar. After the milling processing of the round bar is completed, it takes a long time to unload the round bar by mechanical hands or manual hands, and clamp the next round bar to be processed. This period of time consumes a long time, which is equivalent to the milling processing time of the end of the round bar. During this part of time, the tool of the machine tool cannot perform processing operations, resulting in low work efficiency and poor continuity, and also increases production costs.

[0003] Therefore, how to achieve efficient and low-cost continuous processing of a large number of round rod ends has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The technical problem to be solved by the present invention is: how to realize high-efficiency, low-cost and continuous processing of a large number of round rod ends.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A high-efficiency milling and turning processing device for round bar ends comprises 2n rotating clamping mechanisms arranged in a line along the X direction, the rotating clamping mechanism comprises a rotating seat rotatably connected to a frame and a pneumatic chuck connected to the rotating seat for clamping a round bar body, and a moving seat arranged in the Y direction of the rotating clamping mechanism, the moving seat is connected to the frame through an XY double-axis moving module, and n milling and turning mechanisms arranged in a line along the X direction are connected to the moving seat, the spacing between the central axes of two adjacent milling and turning mechanisms is a, the spacing between two adjacent rotating clamping mechanisms is b, and n is a natural number greater than 1; when n≥2, a=2b;

[0007] In the first state, each milling mechanism contacts the end of the round bar body clamped by the odd-numbered rotary clamping mechanism, and the even-numbered rotary clamping mechanism unloads and clamps the next round bar body;

[0008] In the second state, each milling mechanism contacts the end of the round rod body clamped by the even-numbered rotary clamping mechanism respectively, and the odd-numbered rotary clamping mechanism unloads and clamps the next round rod body.

[0009] Furthermore, in the structure of the high-efficiency milling and turning processing device for the end of a round rod, the central axis of the rotating seat is provided with a through hole for the axial passage of the round rod body, and the pneumatic chuck is located at the Y-direction end of the through hole.

[0010] Furthermore, in the above-mentioned high-efficiency turning and milling processing device structure of the round rod end, a feeding mechanism is provided on the Y-direction reverse side of each rotating seat, and the feeding mechanism includes a stacking trough for stacking the round rod bodies in a vertical direction, and a first cylinder located on the Y-direction reverse side of the bottom of the stacking trough, the round rod body located at the bottom of the stacking trough is coaxial with the through hole, the first cylinder is used to push the round rod body located at the bottom of the stacking trough into the through hole, the first cylinder is a two-stroke cylinder, the first stroke is used to push out the processed round rod body located at the pneumatic chuck, and the second stroke is used to push the round rod body in the through hole to the clamping position of the pneumatic chuck.

[0011] Furthermore, in the structure of the above-mentioned high-efficiency milling processing device for the end of a round rod, the feeding mechanism includes a material guide plate, which is located on one side above the stacking trough, and also includes a material shifting mechanism located below the material guide plate. The material shifting mechanism includes a rotating shaft with an axial direction in the Y direction, and a material shifting gear is coaxially connected to the rotating shaft. The material guide plate is provided with a bar hole for avoiding the material shifting gear, and the tooth tip of the material shifting gear is located at the bar hole.

[0012] Furthermore, the structure of the above-mentioned high-efficiency turning and milling processing device for the ends of round rods also includes 2n material blocking mechanisms, which are movably connected to the frame and rotate the clamping mechanism to unload the material. When clamping the next round rod body, the material blocking mechanism blocks the Y direction of the pneumatic chuck and is used to limit the axial position of the round rod body. When the turning and milling mechanism contacts the end of the round rod body, the corresponding material blocking mechanism disengages from the axial direction of the pneumatic chuck.

[0013] Furthermore, in the above-mentioned high-efficiency milling and turning processing device structure of the round rod end, the material blocking mechanism includes a connecting rod and a second cylinder, the middle part of the connecting rod is pivotally connected to the frame, one end of the second cylinder is pivotally connected to the frame, and the other end is pivotally connected to one end of the connecting rod, and the other end of the connecting rod is provided with a material blocking member for blocking the pneumatic chuck in the Y direction.

[0014] The present invention also relates to a processing method of the above-mentioned round bar end turning and milling high-efficiency processing device, comprising the following steps:

[0015] Each turning and milling mechanism moves to the Y direction of each odd-numbered rotary clamping mechanism through the XY dual-axis moving module, and performs turning and milling processing on the end of the round rod body clamped by the pneumatic chuck of each odd-numbered rotary clamping mechanism; at the same time, the pneumatic chuck of each even-numbered rotary clamping structure releases the clamping of the processed round rod body, removes the round rod body from the pneumatic chuck, and clamps the next round rod body;

[0016] Each turning and milling mechanism moves to the Y direction of each even-numbered rotary clamping mechanism through the XY dual-axis moving module, and performs turning and milling processing on the end of the round rod body positioned and clamped by the pneumatic chuck of each even-numbered rotary clamping mechanism; at the same time, the pneumatic chuck of each odd-numbered rotary clamping structure releases the clamping of the processed round rod body, removes the round rod body from the pneumatic chuck, and clamps the next round rod body.

[0017] Furthermore, in the above processing method, the pneumatic chuck releases the grip of the processed round rod body, removes the round rod body from the pneumatic chuck, and clamps the next round rod body as follows:

[0018] The pneumatic chuck releases its grip on the processed round rod body, and the feeding mechanism feeds the unprocessed round rod body into the through hole, so that the processed round rod body is ejected from the pneumatic chuck from the Y direction. The blocking mechanism is controlled to move to the Y-direction end of the pneumatic chuck to axially position the next round rod body to be processed; the pneumatic chuck is controlled to clamp the round rod body.

[0019] Furthermore, in the above processing method, the feeding mechanism feeds the unprocessed round rod body into the through hole by controlling the first cylinder to move a first stroke, pushing the round rod body at the bottom of the stacking trough into the through hole, and pushing the processed round rod body at the pneumatic chuck out, and controlling the first cylinder to move a second stroke, so that the round rod body in the through hole is pushed to the clamping position of the pneumatic chuck, so that the Y-end of the round rod body contacts the material blocking mechanism.

[0020] Furthermore, in the above processing method, controlling the material blocking mechanism to move to the Y-direction end of the pneumatic chuck specifically includes: controlling the second cylinder to drive the connecting rod to swing, so that the material blocking member blocks the pneumatic chuck in the Y-direction.

[0021] The beneficial effect of the present invention is that after the round rod body is clamped on the pneumatic chuck, it can rotate with the rotating seat, so the milling cutter itself does not need to rotate. It only needs to control the XY dual-axis moving module to drive the moving seat to move in both directions, and switch back and forth between the first state and the second state, so that the round rod bodies on the two adjacent rotating seats can be operated alternately in the processing state and the loose clamping, unloading and clamping state. Since the turning and milling processing time of the end of the round rod body is basically the same as the duration of loose clamping, unloading and clamping, each rotating clamping mechanism always continues to work uninterruptedly in the process of loose clamping, unloading, clamping, turning and milling. Since the number of turning and milling mechanisms is only half of the number of rotating clamping mechanisms, and the turning and milling mechanisms do not need to be provided with a rotating machine tool spindle, the equipment cost is effectively reduced, and efficient and low-cost continuous processing is achieved.

[0037] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0038] Please refer to Figures 1 to 7 The specific embodiment of the present invention relates to a high-efficiency milling and turning processing device for round bar ends, comprising 2n rotating clamping mechanisms 1 arranged in a line along the X direction, the rotating clamping mechanism 1 comprising a rotating seat 11 rotatably connected to a frame and a pneumatic chuck 12 connected to the rotating seat 11 for clamping a round bar body 7, and a moving seat 3 arranged in the Y direction of the rotating clamping mechanism 1, the moving seat 3 is connected to the frame through an XY double-axis moving module 2, and n milling and turning mechanisms 4 arranged in a line along the X direction are connected to the moving seat 3, the spacing between the central axes of two adjacent milling and turning mechanisms 4 is a, and the spacing between two adjacent rotating clamping mechanisms 1 is b, and n is a natural number greater than 1; when n≥2, a=2b;

[0039] In the first state, each milling mechanism 4 contacts the end of the round bar body 7 clamped by the odd-numbered rotary clamping mechanism 1, and the even-numbered rotary clamping mechanism 1 unloads and clamps the next round bar body 7;

[0040] In the second state, each milling mechanism 4 contacts the end of the round rod body 7 clamped by the even-numbered rotary clamping mechanism 1 , and the odd-numbered rotary clamping mechanism 1 unloads and clamps the next round rod body 7 .

[0041] In the above implementation mode, refer to Figure 1 The number of the rotating clamping mechanisms 1 is 8, that is, n=4, and the number of the corresponding turning and milling mechanisms 4 is 4, and the distance between the central axes of two adjacent turning and milling mechanisms 4 is twice the distance between two adjacent rotating clamping mechanisms 1.

[0042] In the above implementation mode, refer to Figure 7 The frame is provided with a bearing seat, and the rotating seat 11 is rotatably connected to the frame through the bearing seat, referring to Figures 1 to 7 The eight rotating seats 11 can be driven to rotate synchronously by a driving mechanism, for example, a motor can drive the eight rotating seats 11 to rotate synchronously at the same time through a pulley transmission or other transmission methods.

[0043] In the above embodiments, the pneumatic chuck 12 is an existing device purchased from outside, which can realize the centering clamping of round bars and is generally used for clamping machine tool tools. The working principle of this part will not be elaborated here.

[0044] In the above embodiment, the turning and milling mechanism 4 includes a milling cutter connected to the tool holder. Since the round rod body 7 can rotate with the rotating seat 11 after being clamped on the pneumatic chuck 12, the milling cutter itself does not need to rotate. It only needs to control the XY dual-axis moving module 2 to drive the moving seat 3 to move in both directions, and switch back and forth between the first state and the second state, so that the round rod bodies 7 on the two adjacent rotating seats 11 can be operated alternately in the processing state and the loose clamping, unloading and clamping state. Since the turning and milling processing time of the end of the round rod body 7 and the duration of loose clamping, unloading and clamping are basically the same, each rotating clamping mechanism 1 always works continuously and uninterruptedly in the process of loose clamping, unloading, clamping and turning and milling. Since the number of turning and milling mechanisms 4 is only half of the number of rotating clamping mechanisms 1, and the turning and milling mechanism 4 does not need to be provided with a rotating machine tool spindle, the equipment cost is effectively reduced, and efficient and low-cost continuous processing is achieved.

[0045] As a preferred embodiment, a through hole 111 is provided in the central axis portion of the rotating seat 11 for the round rod body 7 to pass axially, and the pneumatic chuck 12 is located at the Y-direction end of the through hole 111 .

[0046] Preferably, a feeding mechanism 5 is provided on the Y-direction reverse side of each rotating seat 11, and the feeding mechanism 5 includes a stacking trough 51 for vertically stacking the round rod body 7, and a first cylinder 52 located on the Y-direction reverse side of the bottom of the stacking trough 51, the round rod body 7 located at the bottom of the stacking trough 51 is coaxial with the through hole 111, and the first cylinder 52 is used to push the round rod body 7 located at the bottom of the stacking trough 51 into the through hole 111. The first cylinder 52 is a double-stroke cylinder, and the first stroke is used to push out the processed round rod body 7 located at the pneumatic chuck 12, and the second stroke is used to push the round rod body 7 in the through hole 111 to the clamping position of the pneumatic chuck 12.

[0047] In the above embodiment, the stacking trough 51 cooperates with the double-stroke first cylinder 52, and the rotating shaft 515 structure with a through hole 111 in the middle axis portion, and the double-stroke pushing method of the first cylinder 52 is used to realize the continuous automatic operation of unloading and clamping the round rod body 7 on the corresponding pneumatic chuck 12, omitting the loading and unloading structure through the complex mechanical arm, greatly saving the production cost. Moreover, in the process of pushing the material by the first cylinder 52, since the rotating seat 11 always keeps rotating, it has a certain regulating and sorting effect on the round rod body 7 axially moving in the through hole 111, ensuring that the round rods in the through hole 111 are neatly stacked and pushed forward, further improving the clamping accuracy.

[0048] Preferably, the feeding mechanism 5 includes a material guide plate, which is located on one side above the stacking trough 51, and a material shifting mechanism located below the material guide plate. The material shifting mechanism includes a rotating shaft 515 with an axial direction in the Y direction, and a material shifting gear 516 is coaxially connected to the rotating shaft 515. The material guide plate is provided with a bar hole 5121 for avoiding the material shifting gear 516, and the tooth tip of the material shifting gear 516 is located at the bar hole 5121.

[0049] Preferably, the feeding mechanism 5 includes a material guide plate, which is an N-shaped structure consisting of a first vertical plate 513, an inclined plate 511, an arc plate 512 and a second vertical plate 514 connected in sequence, a stacking trough 51 is formed between the second vertical plate 514 of one material guide plate and the first vertical plate 513 of another adjacent material guide plate, and a strip hole 5121 is provided on the arc plate 512. The feeding mechanism 5 also includes a material shifting mechanism arranged below the inclined plate 511 and the arc plate 512, and the material shifting mechanism includes a rotating shaft 515 with an axial direction in the Y direction, and a material shifting gear 516 is coaxially connected to the rotating shaft 515, and the tooth tip of the material shifting gear 516 is located at the strip hole 5121.

[0050] In the above implementation mode, refer to Figure 4 The unprocessed round rod bodies 7 can be stacked above each inclined plate 511. By controlling the rotation of the rotating shaft 515, the material-moving gear 516 rotates, and the round rod bodies 7 at the strip holes 5121 are moved through the tip of its teeth, and are orderly moved into the stacking groove 51, so that the round rod bodies 7 are automatically and orderly stacked longitudinally in the stacking groove 51.

[0051] Preferably, it also includes 2n material blocking mechanisms 6, which are movably connected to the frame. When the rotating clamping mechanism 1 unloads and clamps the next round rod body 7, the material blocking mechanism 6 blocks the Y direction of the pneumatic chuck 12 and is used for axial limitation of the round rod body 7. When the turning and milling mechanism 4 contacts the end of the round rod body 7, the corresponding material blocking mechanism 6 disengages from the axial direction of the pneumatic chuck 12.

[0052] In the above embodiment, before the first cylinder 52 performs the second stroke movement, by controlling the movement of the material blocking mechanism 6, the end of the round rod body 7 located at the pneumatic chuck 12 pushed by the second stroke movement of the first cylinder 52 can be axially positioned, thereby better ensuring the subsequent turning and milling processing accuracy.

[0053] Preferably, the material blocking mechanism 6 includes a connecting rod 62 and a second cylinder 61, the middle part of the connecting rod 62 is pivoted to the frame, one end of the second cylinder 61 is pivoted to the frame, and the other end is pivoted to one end of the connecting rod 62, and the other end of the connecting rod 62 is provided with a material blocking member 63 for blocking the pneumatic chuck 12 in the Y direction.

[0054] In the above embodiment, a round rod body 7 at the bottom of the stacking trough 51 is pushed into the through hole 111 by the first cylinder 52, so that there are multiple round rod bodies 7 in the through hole 111 at the same time, and the multiple round rod bodies 7 are arranged axially. When the round rod body 7 on the pneumatic chuck 12 of a certain rotating clamping mechanism 1 completes the turning and milling processing, the pneumatic chuck 12 is controlled to release the clamping, and the first stroke of the first cylinder 52 is to push a round rod at the bottom of the stacking trough 51 into the through hole 111, so that the round rod body 7 located at the pneumatic chuck 12 is pushed out and falls to the bottom. A conveyor belt moving along the X direction can also be set below the pneumatic chuck 12 to receive and transport the fallen processed round rod body 7. Then control the second cylinder 61 to drive the stopper 63 to move to the Y position of the central axis of the pneumatic chuck 12, so that the stopper 63 and the Y end of the pneumatic chuck 12 maintain a fixed distance, and then control the first cylinder 52 to move the second stroke, so that the end of the next round rod body 7 is against the stopper 63 for positioning, and then control the pneumatic chuck 12 to clamp the round rod body 7, and then control the second cylinder 61 to drive the stopper 63 to move and separate from the end of the round rod body 7, and then control the XY dual-axis moving module 2 to drive the turning and milling mechanism 4 to contact the end of the round rod body 7 for turning and milling, and repeat this process.

[0055] The present invention also relates to a processing method of the above-mentioned round bar end turning and milling high-efficiency processing device, comprising the following steps:

[0056] Each turning and milling mechanism 4 moves to the Y direction of each odd-numbered rotary clamping mechanism 1 through the XY dual-axis moving module 2, and performs turning and milling processing on the end of the round rod body 7 positioned and clamped by the pneumatic chuck 12 of each odd-numbered rotary clamping mechanism 1; at the same time, the pneumatic chuck 12 of each even-numbered rotary clamping structure releases the clamping of the processed round rod body 7, removes the round rod body 7 from the pneumatic chuck 12, and clamps the next round rod body 7;

[0057] Each turning and milling mechanism 4 is moved to the Y direction of each even-numbered rotating clamping mechanism 1 through the XY dual-axis moving module 2, and the end of the round rod body 7 positioned and clamped by the pneumatic chuck 12 of each even-numbered rotating clamping mechanism 1 is turned and milled; at the same time, the pneumatic chuck 12 of each odd-numbered rotating clamping structure releases the clamping of the processed round rod body 7, removes the round rod body 7 from the pneumatic chuck 12, and clamps the next round rod body 7.

[0058] Preferably, in the above processing method, the pneumatic chuck 12 releases the clamping of the processed round rod body 7, removes the round rod body 7 from the pneumatic chuck 12, and clamps the next round rod body 7 specifically as follows:

[0059] The pneumatic chuck 12 releases its grip on the processed round rod body 7, and the feeding mechanism 5 feeds the unprocessed round rod body 7 into the through hole 111, so that the processed round rod body 7 is pushed out of the pneumatic chuck 12 from the Y direction. The material blocking mechanism 6 is controlled to move to the Y-direction end of the pneumatic chuck 12 to axially position the next round rod body 7 to be processed; the pneumatic chuck 12 is controlled to clamp the round rod body 7.

[0060] Preferably, in the above-mentioned processing method, the feeding mechanism 5 feeds the unprocessed round rod body 7 into the through hole 111 by: controlling the first cylinder 52 to move the first stroke, pushing the round rod body 7 at the bottom of the stacking trough 51 into the through hole 111, and pushing the processed round rod body 7 located at the pneumatic chuck 12 out, and controlling the first cylinder 52 to move the second stroke, so that the round rod body 7 in the through hole 111 is pushed to the clamping position of the pneumatic chuck 12, so that the Y-direction end of the round rod body 7 contacts the material blocking mechanism 6.

[0061] Preferably, in the above processing method, controlling the material blocking mechanism 6 to move to the Y-direction end of the pneumatic chuck 12 specifically includes: controlling the second cylinder 61 to drive the connecting rod 62 to swing, so that the material blocking member 63 blocks the pneumatic chuck 12 in the Y-direction.
