Description

Technical Field

[0001] The present invention relates to the field of processing spiral tracks of rubber tapping machines, and particularly to gear hobbing equipment for rubber tapping machine tracks and a production line for rubber tapping machine tracks. Background Art

[0002] A rubber tapping machine needs to be installed on a spiral track, which is arranged around the periphery of a rubber tree. The rubber tapping machine moves spirally upward along the track and cuts the epidermis of the rubber tree. Currently, a tooth surface is provided on the track, and the rubber tapping machine is provided with a driving gear that cooperates with the tooth surface. After the driving gear rotates, the rubber tapping machine moves. The general manufacturing process of the existing spiral track is as follows: a straight rod is bent into a spiral rod, and then a tooth surface is processed on the outer wall of the spiral rod. However, due to the large pitch of the spiral rod, it is difficult to clamp the spiral rod into the numerical control gear hobbing equipment, resulting in a high processing difficulty for the tooth surface of the track. Summary of the Invention

[0003] The purpose of the present invention is to provide a gear hobbing equipment for rubber tapping machine tracks and a production line for rubber tapping machine tracks to solve one or more technical problems existing in the prior art, and at least provide a beneficial alternative or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] A gear hobbing equipment for rubber tapping machine tracks, comprising:

[0006] A base;

[0007] A linear driving member, which is arranged on the base;

[0008] A rotary driving mechanism, which is arranged on the base. The linear driving member is connected to the rotary driving mechanism, and the linear driving member drives the rotary driving mechanism to move in the front-rear direction;

[0009] A fixture, which is connected to the rotary driving mechanism. The rotary driving mechanism drives the fixture to rotate around an axis extending in the front-rear direction. A spiral groove is provided on the outer wall of the fixture, and the spiral groove spirally extends around the rotation axis of the fixture;

[0010] A tool, which is arranged on the base. The tool is provided with a processing hole that penetrates through in the front-rear direction. The processing hole is located in front of the fixture. A plurality of inner helical teeth are provided on the inner side wall of the processing hole, and the inner helical teeth spirally extend around the rotation axis of the fixture. The extending direction of the inner helical teeth is perpendicular to the tangent direction of the spiral advancement of the fixture.

[0011] The beneficial effects of the present invention are as follows: The spiral rod is placed in the spiral groove of the fixture, and the linear driving member and the rotary driving mechanism jointly drive the fixture to advance spirally from the back to the front, so that the fixture extends into the machining hole of the tool. Since the extending direction of the internal inclined teeth on the inner side wall of the machining hole is perpendicular to the tangential direction of the spiral advance of the fixture, the internal inclined teeth can cut the spiral rod on the spirally advancing fixture, and the internal inclined teeth will not interfere with the spiral advance movement of the fixture. The multiple internal inclined teeth on the inner side wall of the machining hole cut the outer wall of the spiral rod to form a tooth surface, making the spiral rod processed into a track, and the tooth surface processing is relatively simple; moreover, the spirally advancing fixture drives the spiral rod to move relative to the internal inclined teeth, which helps to convert the torque into the pressure of the spiral rod relative to the internal inclined teeth, making the cutting of the spiral rod by the internal inclined teeth smoother.

[0012] As a further improvement of the above technical solution, the internal inclined teeth are divided into multiple steps from the back to the front, and the distances by which the multiple steps protrude towards the axis of the machining hole increase one by one from the back to the front.

[0013] The internal inclined teeth are divided into multiple steps. The rear end of the internal inclined teeth first cuts the spiral rod on the fixture, and the distances by which the multiple steps protrude increase one by one from the back to the front, so that the cutting amounts of the multiple steps gradually increase, avoiding the internal inclined teeth and the spiral rod getting stuck due to excessive cutting amount.

[0014] As a further improvement of the above technical solution, the distance difference between the distances by which every two adjacent steps protrude towards the axis of the machining hole is between 0.02 mm and 0.15 mm.

[0015] Controlling the cutting amount of each step between 0.02 mm and 0.15 mm helps to improve the service life of the internal inclined teeth and avoid the internal inclined teeth being damaged due to excessive cutting amount.

[0016] As a further improvement of the above technical solution, the rubber cutting machine track hobbing equipment further includes a limiting cylinder, the limiting cylinder is arranged in front of the tool, and the limiting cylinder is sleeved on the periphery of the fixture.

[0017] The limiting cylinder in front of the tool is sleeved on the periphery of the fixture, so as to limit the spiral rod, avoid the spiral rod shaking during the process of the internal inclined teeth of the tool cutting the spiral rod, and help to improve the accuracy of the tooth surface formed after the internal inclined teeth cut the spiral rod.

[0018] As a further improvement of the above technical solution, there are multiple spiral grooves, and the multiple spiral grooves are arranged side by side in the front-back direction.

[0019] The multiple spiral grooves are arranged side by side in the front-back direction, so that multiple spiral rods can be installed on the fixture, multiple tracks can be processed at one time, the processing efficiency is improved, and the limiting cylinder can limit multiple spiral rods at the same time to ensure the tooth surface processing accuracy of multiple spiral rods.

[0020] As a further improvement of the above technical solution, the rotary driving mechanism includes:

[0021] A guiding cylinder, on the inner side wall of which there is a guiding groove that spirally extends around the axis of the guiding cylinder;

[0022] A rotating cylinder, which is hinged to the linear driving member, the rotating cylinder is connected to the fixture, on the outer side wall of the rotating cylinder there is a guiding block that spirally extends around the axis of the rotating cylinder, and the guiding block cooperates with the guiding groove.

[0023] The guiding groove of the guiding cylinder cooperates with the guiding block of the rotating cylinder, and the linear driving member drives the rotating cylinder to move forward. The rotating cylinder advances in a spiral manner in a purely mechanical way, without the need to additionally set up an electric control device to drive the rotary driving mechanism, reducing the control difficulty of the rotary driving mechanism and the linear driving member.

[0024] As a further improvement of the above technical solution, on the outer side wall of the fixture there is also a limiting groove, the limiting groove is arranged at the end of the spiral groove, the track hobbing equipment of the rubber tapping machine further includes a limiting block, the limiting block is detachably connected to the limiting groove, the limiting block is provided with a limiting hole, and the limiting hole communicates with the end of the spiral groove.

[0025] After inserting the end of the spiral rod into the limiting hole of the limiting block, the limiting block is installed into the limiting groove, then the spiral rod is clamped into the spiral groove of the fixture, making the clamping of the spiral rod more convenient.

[0026] A track production line of a rubber tapping machine includes a spiral rod processing machine, a spiral rod shaping machine, and the track hobbing equipment of the rubber tapping machine as described above, which are arranged in sequence according to the processing order.

[0027] The straight rod is processed into a spiral rod by the spiral rod processing machine, then the spiral rod shaping machine is used to shape the spiral rod that has deformed after releasing internal stress, and then the spiral rod is placed into the spiral groove of the fixture. The linear driving member and the rotary driving mechanism jointly drive the fixture to advance spirally from back to front, so that the fixture extends into the processing hole of the tool. Since the extending direction of the internal helical teeth on the inner side wall of the processing hole is perpendicular to the tangential direction of the spiral advance of the fixture, the internal helical teeth can cut the spiral rod on the spirally advancing fixture, and the internal helical teeth will not interfere with the spiral advance movement of the fixture. The multiple internal helical teeth on the inner side wall of the processing hole cut the outer wall of the spiral rod to form a tooth surface, making the spiral rod processed into a track, and the tooth surface processing is relatively simple; and the spirally advancing fixture drives the spiral rod to move relative to the internal helical teeth, which helps to convert the torque into the pressure of the spiral rod relative to the internal helical teeth, making the cutting of the spiral rod by the internal helical teeth smoother.

[0028] As a further improvement of the above technical solution, the spiral rod processing machine includes:

[0029] A mold provided with a spiral channel;

[0030] A conveying pipe communicating with the spiral channel and extending horizontally;

[0031] A linear push rod extending into the conveying pipe and moving along the conveying pipe.

[0032] Put a straight rod into the conveying pipe, and then use the linear push rod to push the straight rod to move along the conveying pipe into the spiral channel. The linear push rod continues to push the straight rod to form it along the spiral channel and then process a spiral rod. Using a spiral rod processing machine, spiral rods meeting the requirements of the track of a rubber tapping machine can be processed. Moreover, the processing of the spiral rods is relatively convenient, eliminating the debugging and clamping operations, and the production efficiency is relatively high.

[0033] As a further improvement of the above technical solution, the spiral rod shaping machine includes:

[0034] An upper mold whose bottom surface spirally extends around a vertical axis;

[0035] A lower mold disposed below the upper mold. The top surface of the lower mold spirally extends around a vertical axis. The top surface of the lower mold is provided with a lower spiral groove that spirally extends along the top surface of the lower mold;

[0036] A driving mechanism connected to the upper mold or the lower mold, and the driving mechanism drives the upper mold and the lower mold to approach or separate from each other.

[0037] Put the spiral rod into the lower spiral groove of the lower mold. Subsequently, the driving mechanism drives the upper mold and the lower mold to approach each other. The bottom surface of the upper mold and the lower spiral groove of the lower mold press the spiral rod tightly to shape and correct the spiral rod, so as to facilitate the subsequent gear hobbing equipment of the rubber tapping machine track to process a tooth surface on the spiral rod. The precision of the spiral rod after shaping and correction is relatively high, which helps to improve the precision of the tooth surface processed by the gear hobbing equipment of the rubber tapping machine track.

[0052] Referring to Figures 1 to 5 As shown, the following embodiments are made for the rail hobbing equipment of the rubber tapping machine of the present invention:

[0053] The rail hobbing equipment of the rubber tapping machine includes a base 100, a linear driving member 200, a rotary driving mechanism 300, a fixture 400, a cutter 500, and a limiting cylinder 600.

[0054] Referring to Figures 1 to 2 As shown, the base 100 extends in the front-rear direction. The base 100 includes four fixing columns extending in the front-rear direction, a plurality of support rods extending in the left-right direction, and a plurality of vertically arranged fixing plates. The four fixing columns are arranged in parallel. Seven fixing plates are connected to the four fixing columns to form a rectangular frame extending in the front-rear direction by the four fixing columns. A plurality of support rods are connected to the two lower fixing columns, and the bottoms of the plurality of support rods abut against the ground, so that the base 100 is stably placed on the ground.

[0055] Each fixing plate is provided with a fixing hole penetrating in the front-rear direction.

[0056] The linear driving member 200 is a hydraulic push rod. The linear driving member 200 is installed on the rear side of the base 100. The front and rear ends of the linear driving member 200 are respectively connected to the two adjacent fixing plates at the rearmost side. The movable push rod at the front end of the linear driving member 200 passes through the fixing hole and extends forward. The movable push rod of the linear driving member 200 moves in the front-rear direction.

[0057] Referring to Figure 2 As shown, the rotary driving mechanism 300 includes a guiding cylinder 310 and a rotary cylinder 320. The guiding cylinder 310 is fixed in the fixing hole of the third fixing plate counted from the back to the front. The outer side wall of the guiding cylinder 310 is connected to the fixing plate, and the guiding cylinder 310 is fixed to the base 100.

[0058] The guiding cylinder 310 is in a cylindrical shape. The guiding cylinder 310 is provided with an inner hole penetrating in the front-rear direction. The inner hole is a circular hole. The axis of the inner hole coincides with the axis of the movable push rod of the linear driving member 200. A guiding groove 311 is provided on the inner hole wall of the guiding cylinder 310. The guiding groove 311 spirally extends around the axis of the inner hole of the guiding cylinder 310. The front and rear ends of the guiding groove 311 respectively penetrate through the front and rear end faces of the guiding cylinder 310.

[0059] The rotary cylinder 320 is in a cylindrical shape. The outer side wall of the rotary cylinder 320 is provided with a guiding block 321. The guiding block 321 spirally extends around the axis of the rotary cylinder 320. The front and rear ends of the guiding block 321 extend to the front and rear end faces of the rotary cylinder 320.

[0060] The pitch of the guiding block 321 is the same as that of the guiding groove 311, and the outer diameter of the rotating cylinder 320 matches the inner diameter of the guiding cylinder 310. The rotating cylinder 320 is disposed through the guiding cylinder 310, and the guiding block 321 is slidably disposed in the guiding groove 311. When the rotating cylinder 320 moves in the front-rear direction, the guiding block 321 and the guiding groove 311 cooperate to make the rotating cylinder 320 advance or retreat in a spiral manner.

[0061] Refer to Figure 2 As shown, the movable push rod of the linear driving member 200 is hinged to the transmission rod. The transmission rod extends in the front-rear direction. After passing through the inner hole of the rotating cylinder 320, the transmission rod continues to pass through the fixing holes of a plurality of fixing plates and extends out in front of the base 100. The movable push rod of the linear driving member 200 drives the transmission rod to move in the front-rear direction.

[0062] Refer to Figure 2 As shown, the transmission rod is connected to the end face of the rotating cylinder 320, and the transmission rod is linked with the rotating cylinder 320. The rear end of the transmission rod is hinged to the movable push rod of the linear driving member 200, so that the transmission rod can rotate relative to the movable push rod of the linear driving member 200 about an axis extending in the front-rear direction. When the rotating cylinder 320 makes a spiral forward or backward movement relative to the guiding cylinder 310, the transmission rod also makes a spiral forward or backward movement.

[0063] Refer to Figures 1 to 3 As shown, the fixture 400 is in a cylindrical shape. A plurality of spiral grooves 410 are provided on the outer side wall of the fixture 400. Each spiral groove 410 spirally extends around the axis of the fixture 400, and the plurality of spiral grooves 410 are arranged side by side in the front-rear direction.

[0064] The transmission rod is connected to the axis of the fixture 400, and the transmission rod drives the fixture 400 to make a spiral forward or spiral movement.

[0065] A limiting groove 420 is further formed on the outer side wall of the fixture 400. There are two limiting grooves 420, and the two limiting grooves 420 are respectively disposed at two ends of the spiral groove 410, and the limiting groove 420 communicates with the end of the spiral groove 410.

[0066] Refer to Figure 3 As shown, the shape of the limiting block 430 matches the shape of the limiting groove 420, and the limiting block 430 is in interference fit with the limiting groove 420, so as to facilitate the limiting block 430 to be clamped into the limiting groove 420 and prevent the limiting block 430 from falling off from the limiting groove 420.

[0067] The outer wall of the limiting block 430 is provided with a plurality of limiting holes 431. Each limiting hole 431 penetrates through the limiting block 430. The shape of the limiting hole 431 matches the shape of the spiral groove 410. The plurality of limiting holes 431 are arranged side by side in the front-back direction. So that after the user inserts a plurality of spiral rods into the plurality of limiting holes 431 of the limiting block 430, then inserts the limiting block 430 into the limiting groove 420, and makes the plurality of spiral rods be placed in the spiral groove 410.

[0068] There are two limiting blocks 430. The two limiting blocks 430 are respectively installed at the two ends of the spiral rod. The two limiting blocks 430 are inserted into the two limiting grooves 420 one by one, so that the spiral rod is fixed to the outer wall of the fixture 400.

[0069] Refer to Figures 1 to 3 As shown, the limiting cylinder 600 is in a cylindrical shape. There are two limiting cylinders 600. The two limiting cylinders 600 are distributed at intervals in the front-back direction. The limiting cylinder 600 located at the rear is connected to the fourth fixing plate counted from back to front. The limiting cylinder 600 located at the front is connected to the sixth fixing plate counted from back to front. The transmission rod passes through the inner holes of the two limiting cylinders 600. The two limiting cylinders 600 are relatively fixed to the base 100.

[0070] The inner hole diameter of each limiting cylinder 600 matches the outer diameter of the fixture 400. There is a gap between the inner hole wall of the limiting cylinder 600 and the outer side wall of the fixture 400, so as to prevent the inner hole of the limiting cylinder 600 from hindering the spiral forward or backward movement of the fixture 400. And the gap between the inner hole wall of the limiting cylinder 600 and the outer side wall of the fixture 400 is not greater than the distance that the spiral rod extends out of the fixture 400, so that the inner hole wall of the limiting cylinder 600 can press against the spiral rod located on the outer wall of the fixture 400.

[0071] Refer to Figures 3 to 4 As shown, the tool 500 is installed in the fixing hole of the fifth fixing plate counted from back to front. The tool 500 is relatively fixed to the fixing plate, so the tool 500 is fixed on the base 100. The tool 500 is in a circular ring shape. The tool 500 is provided with a processing hole 510 that penetrates in the front-back direction. The processing hole 510 is a circular hole. The axis of the processing hole 510 coincides with the rotation axis of the fixture 400.

[0072] Refer to Figure 3 And Figure 4 As shown, a plurality of inner helical teeth 520 are provided on the inner hole wall of the processing hole 510. The plurality of inner helical teeth 520 are evenly spaced along the circumferential direction of the processing hole 510. Figures 2 to 4 In, only part of the inner helical teeth 520 are drawn for easy observation. Actually, the plurality of inner helical teeth 520 cover the inner hole wall of the processing hole 510.

[0073] The distance that the inner helical teeth 520 protrude towards the axis of the machining hole 510 is greater than the distance that the spiral rod extends outside the fixture 400, so as to facilitate the inner helical teeth 520 to cut the outer wall of the spiral rod.

[0074] Referring to Figure 4 As shown, each inner helical tooth 520 spirally extends around the axis of the machining hole 510. The inner helical teeth 520 are gradually twisted to the right from the back to the front. The inner helical teeth 520 are divided into 20 steps 521 from the back to the front. All the steps 521 extend towards the axis of the machining hole 510. The distances that multiple steps 521 protrude towards the axis of the machining hole 510 increase one by one from the back to the front. The distance difference between every two adjacent steps 521 protruding towards the axis of the machining hole 510 is between 0.02 mm and 0.15 mm. In this embodiment, the distance difference between every two adjacent steps 521 protruding towards the axis of the machining hole 510 is 0.05 mm.

[0075] Referring to Figure 3 And Figure 4 As shown, the extending direction of the inner helical teeth 520 is perpendicular to the tangent direction of the spiral forward movement of the fixture 400.

[0076] The working process of the rubber tapping machine track hobbing equipment is as follows:

[0077] The linear drive 200 pulls the fixture 400 backward to make a spiral backward movement, so that the spiral groove 410 of the fixture 400 is separated backward from the limit cylinder 600. The operator disassembles the two limit blocks 430, inserts the ends of multiple spiral rods into the limit holes 431 of the two limit blocks 430 one by one, and then installs the two limit blocks 430 into the limit grooves 420 one by one, so that multiple spiral rods are fixed in the spiral groove 410 of the fixture 400.

[0078] The linear drive 200 pushes the fixture 400 forward to make a spiral forward movement. The fixture 400 drives multiple spiral rods to move forward into the limit cylinder 600. The limit cylinder 600 limits multiple spiral rods. Then the spiral rods extend into the machining hole 510 of the tool 500. Multiple inner helical teeth 520 cut the spiral rods making a spiral forward movement, so that tooth surfaces are formed on the outer walls of multiple spiral rods facing the inner helical teeth 520, and the rubber tapping machine track is machined.

[0079] Finally, the fixture 400 moves to the front of the limit cylinder 600 located in the front, so that the two limit blocks 430 and multiple spiral rods are exposed, so as to facilitate the operator to take out the multiple machined tracks and re-clamp the spiral rods to be machined.

[0080] Referring to Figures 6 to 8 As shown, the following embodiments are made for the rubber tapping machine track production line of the present invention:

[0081] The rubber tapping machine rail production line includes a screw rod processing machine 700, a screw rod shaping machine 800, and a gear hobbing device for rubber tapping machine rails.

[0082] As shown in Figure 6 the figure, the screw rod processing machine 700, the screw rod shaping machine 800, and the gear hobbing device for rubber tapping machine rails are arranged in sequence according to the processing order of the rubber tapping machine rails.

[0083] As shown in Figure 7 the figure, the screw rod processing machine 700 includes a fixing frame, a mold 710, a conveying pipe 720, and a linear push rod 730. The mold 710, the conveying pipe 720, and the linear push rod 730 are all arranged on the fixing frame.

[0084] The interior of the mold 710 is provided with a spiral channel that spirally extends around the vertical axis. The spiral channel penetrates the top end face and the bottom end face of the mold 710. The rear end of the conveying pipe 720 is connected to the top end of the spiral channel, and the conveying pipe 720 extends in the front-rear direction.

[0085] The linear push rod 730 is a hydraulic push rod. The linear push rod 730 extends into the front end of the conveying pipe 720. A straight rod is placed into the conveying pipe 720. The linear push rod 730 pushes the straight rod backward to move to the top end of the spiral channel. Subsequently, the linear push rod 730 continues to push the straight rod backward so that the straight rod bends and forms along the spiral channel, and the straight rod is extruded into a spiral rod.

[0086] As shown in Figure 8 the figure, the screw rod shaping machine 800 includes an upper mold 810, a lower mold 820, and a driving mechanism. The upper mold 810 and the lower mold 820 are arranged opposite to each other up and down. Both the upper mold 810 and the lower mold 820 are circular arcs extending up and down.

[0087] The bottom surface of the upper mold 810 spirally extends around the vertical axis. The top surface of the lower mold 820 extends around the vertical axis. The top surface of the lower mold 820 is provided with a lower spiral groove 821. The lower spiral groove 821 spirally extends along the top surface of the lower mold 820. The bottom surface of the upper mold 810 is provided with an upper spiral groove. The upper spiral groove spirally extends along the bottom surface of the upper mold. The upper spiral groove and the lower spiral groove 821 are arranged opposite to each other up and down.

[0088] The driving mechanism is connected to the lower mold 820. The driving mechanism drives the lower mold 820 to move upward, so that the lower spiral groove 821 and the upper spiral groove close together. The cross-sectional shapes of the upper spiral groove and the lower spiral groove 821 are both circular arcs.

[0089] After placing the spiral rod into the lower spiral groove 821, the driving mechanism drives the lower mold 820 to move upward, so that the lower spiral groove 821 and the upper spiral groove close together. The lower spiral groove 821 and the upper spiral groove straighten and correct the spiral rod. Then, the straightened spiral rod is taken out and placed into the gear hobbing device for rubber tapping machine rails. The gear hobbing device for rubber tapping machine rails processes the outer wall of the spiral rod to produce a tooth surface.
