Description

Technical Field

[0001] The present invention relates to the technical field of gear shaft housing processing, and particularly to an automatic arc cutting device for gear shaft housing processing. Background Technique

[0002] A gear shaft housing is a mechanical transmission device composed of a shaft gear and a housing, mainly used to reduce the rotational speed of the output shaft of the motor to meet the working requirements of the load shaft. At the same time, in order to eliminate the internal stress of the gear shaft housing and improve the service performance of the gear shaft housing, it is usually necessary to cut the gear shaft housing.

[0003] In the prior art for cutting gear shaft housings, generally, a cutting assembly is directly used to complete the cutting effect on the gear shaft housing. However, no matter what kind of cutting assembly, corresponding debris will be generated when cutting the gear shaft housing, and these debris often adhere to the surface of the gear shaft housing after cooling.

A fifth connecting rod is vertically installed at the bottom of the first top support rod. The fifth connecting rod is slidably arranged inside the connecting sleeve.

[0014] As an alternative solution of the automatic arc cutting equipment for gear shaft box machining according to the present invention, wherein: A sixth connecting rod is vertically installed at the top of the second top support rod. The sixth connecting rod is slidably arranged inside the connecting sleeve. A first spring for resetting is also arranged inside the connecting sleeve.

[0015] As an alternative solution of the automatic arc cutting equipment for the machining of gear shaft boxes according to the present invention, wherein: above the grinding belt, a third connecting rod for driving the first supporting rod to move is installed, a fourth connecting rod is arranged between the third connecting rod and the first supporting rod, and a knocking piece for cleaning the grinding belt is also installed on the third connecting rod, and a second connecting rod is vertically installed at the top of the third connecting rod.

[0018] The present invention has the following beneficial effects:

[0019] 1. For the automatic arc cutting equipment for the machining of gear shaft boxes, by arranging a grinding component on the moving seat, not only can the grinding component move horizontally along with the moving seat, so that after the arc cutting head finishes cutting the gear shaft box, the grinding component can immediately finish grinding the debris adhered to the gear shaft box in real time, but also during the process of the grinding component moving along with the moving seat through the arrangement of the hydraulic rod, a reciprocating longitudinal movement can be completed, thereby effectively improving the grinding effect of the grinding component on the gear shaft box.

[0020] 2. For the automatic arc cutting equipment for the machining of gear shaft boxes, after the sliding block moves, the first sliding rod arranged inside the sliding block will slide inside the moving sliding groove. Since the opening shape of the first moving position in the moving sliding groove is a kind of wave shape, and the wave crests and wave troughs are both arranged in a linear array, when the first sliding rod slides inside the first moving position, the first sliding rod will move up and down reciprocally, thereby driving the knocking piece to intermittently knock the grinding belt, so as to effectively complete the cleaning of the dust and debris adhered to the surface of the grinding belt, and thus extend the service life of the grinding belt.

[0021] 3. For the automatic arc cutting equipment used for machining the gear shaft housing, after the first sliding rod slides from the first moving position in the moving chute into the second moving position, the first sliding rod will drive the first top support rod to move further downward at this time, so that the second top support rod can complete the top support effect on the grinding belt. When the sliding block moves to the cutting position of the gear shaft housing, the protrusion generated when the second top support rod presses against the grinding belt also enables the grinding belt to complete the grinding effect on the cutting position of the gear shaft housing to a certain extent, thereby further improving the grinding efficiency of the grinding belt on the gear shaft housing.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Example 1, please refer to Figures 1-4 , an automatic arc cutting device for machining a gear shaft housing, including a cutting table 1, on which a cutting guard plate 101 is installed. When the cutting assembly 2 performs arc cutting on the gear shaft housing, corresponding flying chips will be generated by the gear shaft housing, and this part of the flying chips may cause damage to the safety of the operator. Through the setting of the cutting guard plate 101, this situation can be avoided to a certain extent.

[0036] A positioning groove 103 for positioning and placing the gear shaft housing is provided on the top surface of the cutting table 1. Through the setting of the positioning groove 103, the user can also effectively place the gear shaft housing to be cut on the cutting table 1. It should be noted that a positioning member for positioning and clamping the gear shaft housing is also provided inside the positioning groove 103. Such a positioning member is a commonly used positioning member in the art, and the user can adjust it according to the actual situation, and no more details will be described here.

[0037] The cutting assembly 2 is composed of a moving seat 201, an arc cutting base 202 and an arc cutting head 203. A moving lead screw 102 is installed on the cutting guard plate 101, and the moving seat 201 is threadedly arranged on the moving lead screw 102. Since an external motor is also installed on the cutting guard plate 101, and a fixed connection is formed between the output end of the external motor and the moving lead screw 102, when the gear shaft housing to be cut is positioned and clamped, the user can start the external motor. At this time, the moving lead screw 102 will rotate, thereby driving the moving seat 201 to perform synchronous lateral movement on the cutting table 1.

[0038] The electric arc cutting base 202 is vertically installed on the bottom surface of the moving seat 201, and an electric arc cutting head 203 is arranged on the electric arc cutting base 202. With this setting, when the moving seat 201 moves, the electric arc cutting base 202 and the electric arc cutting head 203 can synchronously follow the moving seat 201 to move horizontally, and then complete the electric arc cutting of the gear axle box during the subsequent movement.

[0039] A second chute 204 is formed on the moving seat 201. The grinding assembly 3 is composed of a grinding guard plate 301, a grinding belt 302 and a sliding block 304. A slider is installed on the side of the sliding block 304, and the slider is slidably arranged inside the second chute 204. A first connecting rod 303 for connection is also arranged between the grinding guard plate 301 and the sliding block 304. It should be noted that the slider only slides inside the second chute 204 and will not be separated from the second chute 204. Therefore, in this way, when the moving seat 201 moves, the entire grinding assembly 3 will follow the moving seat 201 to move synchronously.

[0040] The output end of a hydraulic rod 305 is also connected to the sliding block 304. With this setting, when the user moves the moving seat 201, the hydraulic rod 305 is synchronously started, so that when the sliding block 304 moves horizontally following the moving seat 201, a longitudinal moving effect on the moving seat 201 is completed. And since a first chute 104 for the hydraulic rod 305 to slide is formed on the cutting guard plate 101, this setting also avoids the situation that the hydraulic rod 305 gets stuck when moving. Refer to Figure 2 It can be seen that the hydraulic seat connected to the hydraulic rod 305 is slidably arranged inside the chute formed at the rear end of the cutting guard plate 101. With this setting, when the hydraulic rod 305 moves synchronously with the sliding block 304, it can also be carried out stably.

[0041] A splash guard 206 is vertically installed at the bottom of the moving seat 201. The splash guard 206 is provided to prevent the debris splashed when the electric arc cutting head 203 cuts the gear axle from affecting the grinding assembly 3. A driving shaft rod 320 and a driven shaft rod 321 are also arranged inside the grinding guard plate 301. A first connecting rotating rod 322 and a second connecting rotating rod 323 are respectively arranged on the driving shaft rod 320 and the driven shaft rod 321. The first connecting rotating rod 322 and the second connecting rotating rod 323 are both rotatably arranged on the grinding guard plate 301, and a grinding belt 302 is drivingly arranged on the driving shaft rod 320 and the driven shaft rod 321.

[0042] A moving rack 207 is provided on the splash guard 206. One end of the first connecting rotating rod 322 close to the splash guard 206 is installed with a moving gear 324. The moving gear 324 meshes with the moving rack 207. Through the above setting, when the sliding block 304 longitudinally moves on the moving seat 201, through the meshing between the moving rack 207 and the moving gear 324, the driving shaft rod 320 can be effectively rotated. After the driving shaft rod 320 rotates, the grinding belt 302 provided on the driving shaft rod 320 and the driven shaft rod 321 will also rotate synchronously. At this time, the arc cutting head 203 moves under the movement of the moving seat 201, and partial arc cutting of the gear box is also completed. And due to the arc cutting around the cutting part of the gear box, some debris adheres to it. At this time, the longitudinally moving and rotating grinding belt 302 can effectively complete the grinding effect on the adhered debris. Moreover, since the movement of the sliding block 304 is realized by the extension of the hydraulic rod 305, therefore, the user only needs to control the hydraulic rod 305 to reciprocate and stretch during the movement of the moving seat 201, which can effectively drive the sliding block 304 to longitudinally move back and forth on the moving seat 201, and then effectively let the grinding belt 302 complete the reciprocating grinding effect on the debris around the cutting part of the gear box.

[0043] In this embodiment: After the gear box is positioned and installed, the user can start the external motor. When the external motor drives the moving screw rod 102 to rotate, the moving seat 201 will drive the arc cutting base 202 and the arc cutting head 203 to synchronously move horizontally on the moving screw rod 102, thereby completing the arc cutting effect on the gear box.

[0044] When the moving seat 201 moves to the position of the gear box, the user can start the hydraulic rod 305, so that the sliding block 304 longitudinally moves on the moving seat 201. And through the setting of the moving rack 207 and the moving gear 324, when the sliding block 304 moves, the grinding belt 302 will also rotate accordingly, so as to effectively complete the grinding of the debris adhering to the cutting part of the gear box;

[0045] At the same time, since the movement of the sliding block 304 is realized based on the telescopic movement of the hydraulic rod 305, therefore, by reciprocating the telescopic movement of the hydraulic rod 305, the sliding block 304 will longitudinally move back and forth on the moving seat 201, so that the grinding belt 302 can reciprocally complete the grinding effect on the debris adhering to the cutting part of the gear box, thereby effectively improving the grinding efficiency of the grinding assembly 3.

[0046] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that debris may remain on the grinding belt 302 after the grinding belt 302 grinds the gear box. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer toFigures 1-8 , a third chute 307 is provided inside the sliding block 304, one end of a first sliding rod 306 is slidably arranged inside the third chute 307, and a fixed connection is formed between one end of the first sliding rod 306 and the second connecting rod 308. The other end of the first sliding rod 306 is slidably arranged inside the moving chute 205. The moving chute 205 is composed of a first moving position 2051 and a second moving position 2052. The first moving position 2051 and the second moving position 2052 are alternately arranged and communicated with each other. The shape of the first moving position 2051 is a kind of wave shape, and the wave crests and wave troughs are both arranged in a linear array. It should be noted that the first sliding rod 306 is in the first moving position 2051 at the initial position. Therefore, when the sliding block 304 moves longitudinally on the moving seat 201, the first sliding rod 306 arranged inside the sliding block 304 will slide inside the first moving position 2051.

[0047] A first supporting rod 312 and a second supporting rod 310 are also arranged between the driving shaft rod 320 and the driven shaft rod 321. The first supporting rod 312 is used to support the upper surface of the grinding belt 302, and the second supporting rod 310 is used to support the lower surface of the grinding belt 302.

[0048] A third connecting rod 309 for driving the first supporting rod 312 to move is installed above the grinding belt 302. A fourth connecting rod 311 is arranged between the third connecting rod 309 and the first supporting rod 312. And a knocking member 319 for cleaning the grinding belt 302 is also installed on the third connecting rod 309. The second connecting rod 308 is vertically installed at the top of the third connecting rod 309. Through the above settings, when the first sliding rod 306 moves to the wave crest in the first moving position 2051, the first sliding rod 306 will drive the second connecting rod 308 to move upward, and then drive the third connecting rod 309 and the first supporting rod 312 to move upward synchronously. Since the length of the grinding belt 302 is fixed, when the first supporting rod 312 moves upward, the first supporting rod 312 will support the upper surface of the grinding belt 302, so that the lower surface of the grinding belt 302 is more taut, so that the lower surface of the grinding belt 302 can more closely complete the grinding effect on the debris adhered to the cutting part of the gearbox, thereby improving the grinding efficiency of the grinding belt 302. It should be noted that the length of the grinding belt 302 itself is not slack. Driven by the rotation of the driving shaft rod 320, it can initially meet the grinding effect on the debris adhered to the gearbox. By moving the first supporting rod 312 upward, it is also to further improve the grinding effect of the grinding belt 302, so that the grinding belt 302 can more thoroughly grind some more tightly adhered debris.

[0049] When the first slide bar 306 moves to the trough in the first moving position 2051, the first slide bar 306 will drive the second connecting rod 308 to move downward, and then drive the third connecting rod 309 and the first supporting rod 312 to move downward. Since the knocking member 319 is also installed on the third connecting rod 309, when the first supporting rod 312 descends and releases the support for the polishing belt 302, and the polishing belt 302 also tends to be in a horizontal state, at this time, the continuously descending third connecting rod 309 will drive the knocking member 319 to complete the contact with the upper surface of the polishing belt 302, and then complete the knocking on the upper surface of the polishing belt 302, so as to complete the cleaning effect of the dust and debris adhering to the surface of the polishing belt 302.

[0050] At the same time, since the peaks and troughs in the first moving position 2051 are arranged in a linear array, the first slide bar 306 will move up and down reciprocally during the sliding process in the first moving position 2051, and this reciprocating up and down movement further improves the cleaning efficiency of the above-mentioned polishing belt 302. It should be noted that since a suction member 325 is also provided inside the polishing guard plate 301, and the suction member 325 is an existing suction technology in the art, users can adjust it according to the actual situation and their own needs. The setting of the suction member 325 is to enable the knocking member 319 to knock on the polishing belt 302, and the dust and debris generated by the polishing belt 302 can be adsorbed by the suction member 325, thereby effectively extending the service life of the polishing belt 302.

[0051] In this embodiment: after the slider 304 moves, the first slide bar 306 provided inside the slider 304 will slide inside the moving chute 205. Since the opening shape of the first moving position 2051 in the moving chute 205 is a wavy shape and is arranged in a linear array, during the sliding process of the first slide bar 306 inside the first moving position 2051, the first slide bar 306 will move up and down reciprocally, and then drive the knocking member 319 to intermittently complete the knocking on the polishing belt 302, so as to effectively complete the cleaning effect of the dust and debris adhering to the surface of the polishing belt 302, and further extend the service life of the polishing belt 302.

[0052] Embodiment 3, the purpose of this embodiment is to facilitate the solution of the problem that it is difficult to polish the cutting part of the gearbox. This embodiment is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1-8, according to Embodiment 2, it can be seen that the first moving position 2051 and the second moving position 2052 are alternately arranged and connected. Therefore, when the first sliding rod 306 completes the sliding of the first section of the first moving position 2051, the first sliding rod 306 will slide into the second moving position 2052. Since the opening position of the second moving position 2052 is further closer to the bottom surface of the moving seat 201 on the basis of the trough position of the first moving position 2051, when the first sliding rod 306 slides from the first moving position 2051 into the second moving position 2052, at this time, the first sliding rod 306 will further move downward on the basis of the maximum downward movement position of the first moving position 2051, and at this time, the sliding block 304 just moves directly above the cutting position of the gear shaft housing.

[0053] A connecting sleeve 314 is also provided between the first top strut 312 and the second top strut 310. A fifth connecting rod 313 is vertically installed at the bottom of the first top strut 312, and the fifth connecting rod 313 is slidably arranged inside the connecting sleeve 314. A sixth connecting rod 315 is vertically installed at the top of the second top strut 310, and the sixth connecting rod 315 is slidably arranged inside the connecting sleeve 314. Through the above setting, when the first top strut 312 moves, the second top strut 310 will move accordingly following the first top strut 312. However, when the first sliding rod 306 slides in the second moving position 2052 to a position parallel to the trough of the first moving position 2051, at this time, the first top strut 312 will drive the second top strut 310 to move into contact with the polishing belt 302. Before this, the second top strut 310 will not come into contact with the polishing belt 302. Therefore, even if the first sliding rod 306 still drives the first top strut 312 to move downward, the second top strut 310 will be restricted by the polishing belt 302 and thus unable to move. However, the fifth connecting rod 313 provided on the first top strut 312 will move downward accordingly inside the connecting sleeve 314 under the continuous downward movement of the first top strut 312. Moreover, this setting also ensures that when the first top strut 312 moves reciprocally up and down before, the second top strut 310 will not affect the polishing belt 302.

[0054] It should be noted that limit plates are provided on both the fifth link 313 and the sixth link 315. The purpose of setting the limit plates is to enable the fifth link 313 and the sixth link 315 to only slide inside the connecting sleeve 314 and will not separate from the connecting sleeve 314. Therefore, when the fifth link 313 moves further downward, the limit plate provided on the fifth link 313 will contact the limit plate provided on the sixth link 315. Since the downward movement of the first slide bar 306 has not stopped at this time, when the first slide bar 306 continues to move downward, the limit plate provided on the sixth link 315 will be squeezed by the limit plate provided on the fifth link 313, thereby driving the second support rod 310 to continue to move. And at this time, the second support rod 310 has already completed the contact with the grinding belt 302. Therefore, when the second support rod 310 continues to move downward, the lower surface of the grinding belt 302 will be supported by the second support rod 310, so that a certain bulge will be generated on the surface of the grinding belt 302 at this place. And this bulge also enables the grinding belt 302 to effectively complete the grinding effect on the cutting part of the gearbox, thereby further improving the grinding effect on the gearbox.

[0055] A fourth chute 317 is also provided inside the grinding guard plate 301. A second spring 318 for resetting is provided inside the fourth chute 317. Both ends of the first support rod 312 are slidably provided inside the corresponding fourth chute 317. By providing the fourth chute 317, not only can the first support rod 312 move more stably when moving, but also when the first support rod 312 moves further downward, the second spring 318 will be squeezed at this time. When the first support rod 312 is reset later, it can be quickly reset by the reset elastic force of the second spring 318.

[0056] A first spring 316 for resetting is also provided inside the connecting sleeve 314. The setting of the first spring 316, on the one hand, is to enable the second support rod 310 to be quickly reset by the reset elastic force of the first spring 316 after the subsequent first support rod 312 is reset. On the other hand, the elastic force of the first spring 316 can also ensure that the second support rod 310 will have a certain distance of downward movement space, so that after the first support rod 312 moves further downward, the second support rod 310 can complete the support effect on the grinding belt 302, and then complete the grinding effect on the cutting part of the gearbox.

[0057] When the first slide bar 306 slides from the second moving position 2052 in the moving chute 205 into the next first moving position 2051, the second top support bar 310 will be reset accordingly, and the extrusion and support effect on the grinding belt 302 will be released. Moreover, the movement of the first slide bar 306 inside the next first moving position 2051 will also repeat the effect of the second embodiment. When the hydraulic rod 305 retracts, the slider 304 will be reset on the moving seat 205 accordingly and repeat the moving effect of the second embodiment and the above. It should be noted that at this time, the rotation direction of the grinding belt 302 is reversed, so the grinding direction of the grinding belt 302 on the gearbox will also change, thereby further improving the grinding effect on the gearbox. And so on.

[0058] In this embodiment: When the first slide bar 306 slides from the first moving position 2051 in the moving chute 205 into the second moving position 2052, the first slide bar 306 will drive the first top support bar 312 to move further downward, so that the second top support bar 310 can complete the support effect on the grinding belt 302. When the slider 304 moves to the cutting position of the gearbox, due to the protrusion generated by the second top support bar 310 when supporting the grinding belt 302, the grinding belt 302 can also complete the grinding effect on the cutting position of the gearbox to a certain extent, so as to further improve the grinding efficiency of the grinding belt 302 on the gearbox.
