Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chain pusher adjustment tools, and in particular to a pusher adjustment tool for conveying chain failure. BACKGROUND

[0002] In modern industrial production, conveying chains are widely used in packaging, assembly lines and production lines, etc. The main function of conveying chains is to transport goods from one workstation to another, thereby realizing the automatic production process. The conveying chain is composed of a series of chain links, each of which is provided with a pusher for clamping the goods. These pushers can firmly clamp the goods to ensure that they do not slip or fall during transportation. However, due to various factors such as wear, pitch elongation or chain jumping, the conveying chain may fail during long-term use. When the conveying chain needs to be repaired or replaced, the pusher must be released from clamping the goods before subsequent disassembly or repair work can be carried out. Therefore, how to effectively release the pusher from clamping the goods to ensure safe and rapid repair work is a problem that needs to be solved in current industrial production.

[0003] The pusher adjustment tool for conveying chain failure with publication number CN111942836B has solved the problem of lack of tools for adjusting the angle of the pusher 200 in the prior art. However, similar structures still have many defects in actual use. For example, the existing pusher adjustment tool usually uses elastic members as supporting power to achieve the purpose of pusher adjustment and release of clamped workpieces. However, the supporting force of the elastic member is limited. When the weight of the pusher exceeds the supporting force that the elastic member can provide, an imbalance between the supporting force and the gravity will occur, resulting in the pusher being unable to turn to a horizontal position, thereby failing to achieve the purpose of releasing the pusher from clamping the workpiece. In addition, different specifications of pushers have different weights and sizes, and the elastic supporting force of the elastic member in the prior art cannot be adjusted for different specifications of pushers. This means that the elastic member can only be used within a limited range and cannot meet the stable adjustment requirements of different sizes and weights of pushers, thereby limiting the application range and stability of the adjustment state of the pusher adjustment tool.

[0004] Therefore, the above technical problems need to be solved. SUMMARY

[0005] In order to overcome the deficiencies of the prior art, the present application provides a push head adjusting tool for a conveying chain fault, so as to solve the problem that the supporting force of the elastic member is limited, when the weight of the push head exceeds the supporting force provided by the elastic member, the imbalance between the supporting force and the gravity will occur, so that the push head cannot be turned to the horizontal position, thereby failing to achieve the purpose of releasing the push head from clamping the workpiece, and the elastic supporting force cannot be adjusted for different specifications of the push head, the applicable range is limited, and the stable adjustment requirement of the push head of different sizes and weights cannot be met, thereby limiting the applicable range and the stability of the adjustment state of the push head adjusting tool.

[0044] The positioning seat 2 is clamped and installed on the top of the chain track 1, and is composed of a mounting plate 201, a clamping plate 202, a transmission bevel gear piece 203 and a connecting rod assembly 204. The inside of the mounting plate 201 is symmetrically provided with two groups of slide rail grooves 2011. The bottom of the mounting plate 201 is movably provided with two groups of clamping plates 202 through the slide rail grooves 2011 and the sliding blocks 2022. The inner side of the clamping plate 202 is fixedly provided with two groups of supporting wheels 2021. The center of the bottom of the mounting plate 201 is rotatably provided with the connecting rod assembly 204. The two ends of the connecting rod assembly 204 are movably connected to the inner sides of the two groups of clamping plates 202 through shaft bolts, respectively. The transmission bevel gear piece 203 is rotatably installed on one side of the bottom of the mounting plate 201 through a bearing seat.

[0045] The sliding block 2022 is fixedly installed on the top of the clamping plate 202.

[0046] The rotating movement of the transmission bevel gear piece 203 can be transmitted to the connecting rod assembly 204, so as to drive the two clamping plates 202 to move relatively, adjust the clamping range of the two clamping plates 202, and facilitate the clamping and positioning of chain tracks 1 of different specifications.

[0047] The supporting wheels 2021 keep in contact with the chain track 1, provide sufficient supporting force and friction force, and ensure that the positioning seat 2 will not deviate or slip, so that the positioning seat 2 can be tightly clamped and stably installed on the chain track 1.

[0048] The adjusting mechanism 3 is fixedly installed at the top of the positioning seat 2, and the adjusting mechanism 3 is composed of a mounting frame 301, a translation seat 302, a lifting seat 303 and a cam transmission assembly 304. The inside of the mounting frame 301 is fixedly installed with two guide sliding rails 3011. The bottom of the translation seat 302 is provided with two guide sliding grooves 3023, and the bottom of the translation seat 302 is movably installed at the top of the two guide sliding rails 3011 through the two guide sliding grooves 3023. Two groups of fixed plates 3021 are fixedly installed on the two sides of the translation seat 302, and the outer sides of the bottom ends of the two groups of fixed plates 3021 are rotatably installed with translation wheels 3022. The cam transmission assembly 304 is rotatably installed at the bottom of the inside of the mounting frame 301. Limiting frames 3024 are fixedly installed on the two sides of the translation seat 302, and the lifting seat 303 is movably installed at the top of the translation seat 302 through the limiting frames 3024.

[0049] The mounting frame 301 provides a core platform for fixing and installing the translation seat 302. The two guide sliding rails 3011 in the mounting frame 301 cooperate with the guide sliding grooves 3023 at the bottom of the translation seat 302, so that the translation movement of the translation seat 302 can be performed in a predetermined direction.

[0050] Every two fixed plates 3021 form a group, and the two groups of fixed plates 3021 are located on the two sides of the translation seat 302, respectively. Therefore, two translation wheels 3022 located on the same side of the four translation wheels 3022 are dynamically connected by resisting the two sides of the translation cam 3042, respectively.

[0051] The fixed plates 3021 and the rotatably installed translation wheels 3022 on the two sides of the translation seat 302 can be stably moved on the guide sliding rails 3011 through the driving of the cam transmission assembly 304, so that the stability and reliability of the movement are improved.

[0052] The lifting seat 303 is composed of a lifting plate 3031, two guide frames 3032 and two adjusting frames 3034. The tops of the two guide frames 3032 are fixedly installed on the two sides of the bottom of the lifting plate 3031. The lifting plate 3031 is provided with two symmetrical adjusting sliding grooves 3033 on one side. The lifting plate 3031 is provided with the two adjusting frames 3034 through the two adjusting sliding grooves 3033 on one side, respectively.

[0053] The cam transmission assembly 304 is composed of a spline transmission assembly 3041, two translation cams 3042 and two lifting cams 3043. The interiors of the two translation cams 3042 and the two lifting cams 3043 are provided with spline holes. Each translation cam 3042 and a lifting cam 3043 form a group. The two translation cams 3042 are respectively sleeved on the outer sides of the two ends of the spline transmission assembly 3041 through the spline holes. The two lifting cams 3043 are respectively sleeved on the outer sides of the two ends of the spline transmission assembly 3041 through the spline holes, and the lifting cam 3043 is located on the outer side of the translation cam 3042.

[0054] It should be noted that the cam transmission assembly 304 is the key driving device, through the cooperation of the spline transmission assembly 3041, two translation cams 3042 and two lifting cams 3043, the cam transmission assembly 304 can realize two-layer driving function; on the one hand, it drives the translation seat 302 to move through the translation cam 3042; on the other hand, it drives the lifting seat 303 to rise through the lifting cam 3043;

[0055] The limiting frame 3024 at both ends of the translation seat 302 supports the movable installation of the lifting seat 303 as a connecting piece, so that the lifting seat 303 can move with the translation seat 302;

[0056] The cam transmission assembly 304 drives the translation seat 302 to move along the guide rail 3011 through the translation wheel 3022 and the fixed plate 3021, and the moving translation seat 302 drives the lifting seat 303 to move horizontally through the limiting frame 3024; at the same time, the cam transmission assembly 304 drives the lifting seat 303 to move up, specifically, the cam transmission assembly 304 drives the lifting plate 3031 to move up through the two guide frames 3032, and the lifting plate 3031 moving up drives the two adjusting frames 3034 to move up;

[0057] The adjusting frame 3034 in the horizontally moving lifting seat 303 is inserted into the bottom of the push head piece 102, and then the adjusting frame 3034 moving up lifts one end of the push head piece 102, so as to adjust the push head piece 102 to a horizontal state, and release the clamping of the workpiece by the two push head pieces 102, so as to take out the workpiece;

[0058] It should be noted that the driving mechanism 4 provides driving force for the adjusting mechanism 3, so that the adjusting mechanism 3 can more accurately and quickly complete the task of adjusting the state of the push head piece 102;

[0059] Specifically, the spline transmission assembly 3041 is driven to rotate by the driving mechanism 4, the rotating spline transmission assembly 3041 drives the two ends of the translation cam 3042 and the lifting cam 3043 to rotate synchronously, the two rotating translation cams 3042 respectively horizontally abut against the two translation wheels 3022 arranged oppositely, the moving translation wheels 3022 drive the translation seat 302 to move stably on the guide rail 3011 through the fixed plate 3021; the moving translation seat 302 cooperates with the two guide frames 3032 through the two adjusting frames 3034, so that the lifting plate 3031 can move with the translation seat 302, and the moving lifting plate 3031 drives the two adjusting frames 3034 at one end to move to the bottom of the sinking end of the push head piece 102;

[0060] The two lifting cams 3043 rotating simultaneously upwardly abut the two guide frames 3032, drive the lifting plate 3031 to move upwardly, the lifting plate 3031 moving upwardly drives the two adjusting frames 3034 to move upwardly, and one end of the push head 102 sinks and lifts upwardly; the push head 102 is rotated to a horizontal state around the shaft bolt through the horizontal movement and the lifting movement of the adjusting frame 3034 at the same time, which can effectively release the clamping of the push head 102 on the workpiece and facilitate the quick taking and placing of the workpiece;

[0061] The spline transmission assembly 3041 is connected with the driving mechanism 4 through a worm gear transmission, the worm gear transmission has a self-locking function, so that the push head 102 is locked in a horizontal state and rigidly supported during the process of releasing the clamping of the push head 102, so as to avoid the push head 102 from overturning due to gravity imbalance and ensure that the push head 102 of different specifications can be maintained in a horizontal state;

[0062] As shown in Figure 10 , the adjusting frame 3034 is composed of a lifting frame 3035, a threaded rod 3036, a nut 3037 and a contact wheel 3038, the bottom end of the contact wheel 3038 is rotatably installed at the bottom end of the lifting frame 3035, the bottom end of the threaded rod 3036 is fixedly installed at the top end of the lifting frame 3035, the top end of the threaded rod 3036 extends to the top of the mounting frame 301 through the adjusting sliding slot 3033, and the nut 3037 is threadedly sleeved on the outside of the threaded rod 3036;

[0063] It should be noted that the position of the nut 3037 on the outside of the threaded rod 3036 is rotated to release the locking of the threaded rod 3036, so that the threaded rod 3036 moves in the adjusting sliding slot 3033, the distance between the two lifting frames 3035 is adjusted, the specifications of the conveying chain condition 101 are adjusted, and the adjusting frame 3034 is suitable for conveying chain conditions 101 of different specifications; the lifting frame 3035 contacts the push head 102 through the contact wheel 3038, the rotatability of the contact wheel 3038 reduces the friction with the bottom surface of the push head 102, and the push head 102 can be flexibly overturned around the shaft.

[0064] As shown in Figures 11 to 12 , the spline transmission assembly 3041 is composed of a worm gear 3044, two transmission rods 3045, two first spline rods 3046, two second spline rods 3047 and two mounting wheels 3048, one end of each of the two transmission rods 3045 is fixedly installed at both ends of the worm gear 3044, one end of each of the two first spline rods 3046 is fixedly installed at the other end of each of the transmission rods 3045, one end of each of the two second spline rods 3047 is inserted into the other end of each of the two first spline rods 3046 through spline, one end of each of the two mounting wheels 3048 is inserted into the other end of each of the two second spline rods 3047 through spline, and the other end of each of the two mounting wheels 3048 is rotatably inserted into the inner wall of the mounting frame 301.

[0065] It should be noted that the worm gear 3044 as the power source of the whole assembly, through the fixed installation of the transmission rod 3045 at both ends to the first spline rod 3046 torque transmission; the first spline rod 3046 is connected with the second spline rod 3047 through spline, driving the second spline rod 3047 to rotate synchronously; through the transmission of torque step by step, the whole assembly can efficiently and stably transmit power; and the installation wheel 3048 connected by spline supports the worm gear 3044, so as to realize the effect of stable power transmission; through the spline connection of the first spline rod 3046, the second spline rod 3047 and the installation wheel 3048, the installation and disassembly process is simplified.

[0066] As shown in Figures 7 to 8 The driving mechanism 4 is composed of a servo motor 401 and a worm gear 402. The servo motor 401 is fixedly installed on one side of the mounting frame 301. One end of the worm gear 402 is fixedly connected with the output end of the servo motor 401 through a shaft. The worm gear 402 is meshingly connected with the worm gear 3044.

[0067] It should be noted that the servo motor 401 drives the worm gear 402 to rotate through the shaft at the output end. The rotation of the worm gear 402 is transmitted to the worm gear 3044 through the shaft, so that the worm gear 3044 and the worm gear 402 form a worm and gear transmission relationship, and the worm and gear has a self-locking characteristic. After stopping transmission, mechanical locking is formed, effectively preventing the worm gear 3044 and the worm gear 402 from rotating again due to external factors or other loads, and realizing the locking function.

[0068] As shown in Figures 3 to 5 The connecting rod assembly 204 is composed of a rotating plate 2041, a traction rod 2042 and two linkage bevel gears 2043. The rotating plate 2041 is rotatably installed at the center of the bottom of the mounting plate 201. The linkage bevel gears 2043 are fixedly installed at the center of the bottom of the rotating plate 2041. One side of the linkage bevel gears 2043 is meshingly connected with one end of the transmission bevel gear 203. One end of the two traction rods 2042 is respectively installed at both ends of the bottom of the rotating plate 2041 through shaft bolts. The other end of the two traction rods 2042 is respectively movably connected with the inner sides of the two clamping plates 202 through shaft bolts.

[0069] It should be noted that the rotating transmission bevel gear 203 drives the rotating plate 2041 to rotate through the meshingly connected linkage bevel gears 2043. The rotation of the rotating plate 2041 will cause the angle of the traction rod 2042 to change, thereby driving the two clamping plates 202 to open and close. This is convenient for adjusting the clamping spacing of the two clamping plates 202 according to the specifications of the chain track 1, and ensures that the two clamping plates 202 are stably clamped on the chain track 1.
