Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parts, and particularly relates to an assembly auxiliary frame for a double-balanced crankshaft timing gear. Background Technique

[0002] An engine crankshaft is generally stored on a bracket. The bracket itself is only used for storing the crankshaft alone and cannot realize the assembly of the crankshaft timing gear on the bracket. At the same time, due to different size specifications of the crankshaft, different brackets are needed for storage.

[0003] At present, during the storage process of the timing gear, the timing gear needs to be carried to the bracket and then stored. This process cannot realize the automatic placement of the timing gear. When there are many timing gears, the handling burden of the staff is greatly increased, thereby reducing the placement efficiency of the timing gear. For this reason, we provide an assembly auxiliary frame for a double-balanced crankshaft timing gear to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an assembly auxiliary frame for a double-balanced crankshaft timing gear. Through the specific structural design of the placement component, clamping component, first power driving component and second power driving component, the problems such as the existing timing gear cannot be automatically placed are solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an assembly auxiliary frame for a double-balanced crankshaft timing gear, which includes a placement component, a clamping component, a first power driving component and a second power driving component. The placement component includes a bearing plate, and the bearing plate is installed on an external frame. The clamping component is installed above the bearing plate. The clamping components are symmetrically arranged on both sides of the gear. The clamping component includes two clamping plates, and the clamping plates are symmetrically arranged on the circumferential side of the gear bearing. The first power driving component is installed above the clamping component. The first power driving component includes a bidirectional threaded rod, and the two clamping components are controlled to move through the bidirectional threaded rod. The second power driving component is installed above the bearing plate. The second power driving component includes a driving rack, and the clamping component is driven to move through the driving rack.

[0007] The utility model is further arranged such that two placement frames are fixedly arranged on the top of the bearing plate. The two placement frames are symmetrically arranged. A plurality of placement grooves are opened on the top of the placement frames, and the placement grooves on the two placement frames correspond to each other one by one.

[0008] The present utility model is further configured such that two U-shaped frames are fixedly arranged on the top of the bearing plate, and the two U-shaped frames are symmetrically arranged on both sides of the placing rack. A connecting plate is fixedly arranged inside one of the U-shaped frames, and the other U-shaped frame is slidably matched with the driving rack. A moving plate is slidably arranged on one side of the connecting plate. A first motor is installed at the bottom of the moving plate, and the output end of the first motor penetrates through the top of the moving plate and is fixedly connected with a positioning threaded rod.

[0009] The present utility model is further configured such that the clamping assembly further includes a limiting frame, and the limiting frame is slidably matched with the clamping plate. One end of the clamping plate is fixedly provided with a linkage inclined plate, and the linkage inclined plate is slidably matched with the limiting frame.

[0010] The present utility model is further configured such that a pushing and pulling inclined plate is slidably arranged inside the limiting frame, and the pushing and pulling inclined plate is adapted to the corresponding linkage inclined plate. An ear plate is fixedly arranged on one side of the pushing and pulling inclined plate, and a cylinder is installed on one side of the limiting frame, and the output end of the cylinder is fixedly connected with the ear plate.

[0011] The present utility model is further configured such that the first power driving assembly further includes a moving frame, and two fixing plates are fixedly arranged at the bottom of the moving frame. A second motor is installed on one side of one of the fixing plates, and the output end of the second motor is fixedly connected with the bidirectional threaded rod.

[0012] The present utility model is further configured such that two positioning plates are slidably arranged at the bottom of the moving frame, and the two positioning plates are located between the two fixing plates. The other end of the cylinder is installed on one side of the corresponding positioning plate, and both of the positioning plates are in threaded fit with the bidirectional threaded rod.

[0013] The present utility model is further configured such that the second power driving assembly further includes a driving gear, and the driving gear is rotatably matched with the corresponding U-shaped frame. The driving gear is meshed with the driving rack, and a third motor is installed on the surface of the U-shaped frame near the driving gear, and the output end of the third motor is fixedly connected with the driving gear.

[0014] The present utility model has the following beneficial effects:

[0015] In the present utility model, a first motor drives a first power driving assembly to move, and two clamping assemblies move synchronously. When the clamping assemblies move to both sides of the timing gear, the first power driving assembly drives two clamping plates to move towards each other until the timing gear is tightly clamped. Subsequently, the first motor is controlled to rotate in the reverse direction to drive the first power driving assembly to move in the reverse direction, and the two clamping assemblies move in the reverse direction. Above the placement rack, the two clamping assemblies are controlled to move along the bearing plate through a second power driving assembly. Subsequently, the first motor is continuously controlled to drive the first power driving assembly to move, and the two clamping assemblies move synchronously to drive the timing gear to move until the timing gear moves into the placement groove. This process can achieve the automatic placement of the timing gear and improve the placement efficiency of the timing gear.

[0016] In the present utility model, two air cylinders are controlled to drive corresponding ear plates to move. The push-pull inclined plate moves to drive the corresponding linkage inclined plate to move. Under the action of the elastic resetting member, the corresponding two clamping plates move towards each other. At this time, the two clamping plates clamp the bearing of the corresponding timing gear. At this time, the timing gear is tightly clamped by the clamping assembly, thereby improving the stability during the movement of the gear and greatly improving the placement accuracy of the gear.

[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] For the specific first embodiment, please refer to Figures 1-5 , the present invention is an assembly auxiliary rack for a double-balanced crankshaft timing gear, including a placing component 1, a clamping component 2, a first power driving component 3 and a second power driving component 4. The placing component 1 includes a bearing plate 101, and the bearing plate 101 is installed on an external frame. The clamping component 2 is installed above the bearing plate 101. The clamping component 2 is symmetrically arranged on both sides of the gear. The clamping component 2 includes two clamping plates 201, and the clamping plates 201 are symmetrically arranged on the circumferential side of the gear bearing. The first power driving component 3 is installed above the clamping component 2. The first power driving component 3 includes a bidirectional threaded rod 301, and the two clamping components are controlled to move through the bidirectional threaded rod 301. The second power driving component 4 is installed above the bearing plate 101. The second power driving component 4 includes a driving rack 401, and the clamping component 2 is driven to move through the driving rack 401.

[0028] Specifically, two placing racks 102 are fixedly arranged on the top of the bearing plate 101. The two placing racks 102 are symmetrically arranged. A plurality of placing grooves 103 are opened on the top of the placing rack 102, and the placing grooves 103 on the two placing racks 102 correspond to each other one by one.

[0029] Further, two U-shaped frames 104 are fixedly arranged on the top of the carrier plate 101. The two U-shaped frames 104 are symmetrically arranged on both sides of the placement rack 102. A connecting plate 105 is fixedly arranged inside one of the U-shaped frames 104. The other U-shaped frame 104 is slidably matched with the driving rack 401. A moving plate 106 is slidably arranged on one side of the connecting plate 105. A first motor 107 is installed at the bottom of the moving plate 106. The output end of the first motor 107 penetrates to the top of the moving plate 106 and is fixedly connected with a positioning threaded rod 108.

[0030] The operation process of this embodiment is as follows: In the initial state, the two clamping components 2 are farthest apart. The clamping component 2 is at the rightmost side of the carrier plate 101 (see the appendix Figure 1 for details). The two clamping plates 201 in the clamping component 2 are farthest apart. At this time, the timing gear to be placed is below the clamping component 2. Then, the first motor 107 drives the first power driving component 3 to move, and the two clamping components 2 move synchronously. When the clamping component 2 moves to both sides of the timing gear, the first power driving component 3 is used to control the two clamping components 2 to move towards each other until the two clamping components 2 correspond to the corresponding timing gear bearings (each clamping plate 201 is on the circumferential side of the corresponding timing gear bearing). At this time, the corresponding two clamping plates 201 are controlled to move towards each other. At this time, the timing gear is tightly clamped. Then, the first motor 107 is controlled to rotate in the reverse direction to drive the first power driving component 3 to move the two clamping components 2 synchronously in the reverse direction. When the two clamping components 2 move above the placement rack 102, the second power driving component 4 is used to control the two clamping components 2 to move leftward along the carrier plate 101 until the timing gear moves above the corresponding placement groove 103. Then, the first motor 107 is continuously controlled to drive the first power driving component 3 to move, and the two clamping components 2 move synchronously to drive the timing gear to move until the timing gear moves into the placement groove 103. Then, the two clamping plates 201 are controlled to move away from each other. At this time, the clamping of the timing gear is released. Then, the first motor 107 is controlled to drive the first power driving component 3 to move in the reverse direction, and the two clamping components 2 move synchronously to drive the timing gear to move in the reverse direction. Then, the second power driving component 4 is used to control the two clamping components 2 to move rightward along the carrier plate 101 until the two clamping components 2 return to the initial state.

[0031] Specific Embodiment 2, on the basis of Specific Embodiment 1, the clamping assembly 2 further includes a limit frame 202, and the limit frame 202 is slidably matched with the clamping plate 201 (an elastic reset member is provided between the clamping plate 201 and the limit frame 202). One end of the clamping plate 201 is fixedly provided with a linkage inclined plate 203, and the linkage inclined plate 203 is slidably matched with the limit frame 202. A push-pull inclined plate 204 is slidably arranged inside the limit frame 202, and the push-pull inclined plate 204 is adapted to the corresponding linkage inclined plate 203. One side of the push-pull inclined plate 204 is fixedly provided with an ear plate 205, and a cylinder 206 is installed on one side of the limit frame 202. The output end of the cylinder 206 is fixedly connected to the ear plate 205.

[0032] Specifically, the first power driving assembly 3 further includes a moving frame 302. Two fixing plates 303 are fixedly provided at the bottom of the moving frame 302. A second motor 304 is installed on one side of one of the fixing plates 303. The output end of the second motor 304 is fixedly connected to the bidirectional threaded rod 301. Two positioning plates 305 are slidably arranged at the bottom of the moving frame 302. The two positioning plates 305 are located between the two fixing plates 303. The other end of the cylinder 206 is installed on one side of the corresponding positioning plate 305. Both of the two positioning plates 305 are in threaded cooperation with the bidirectional threaded rod 301. When the two clamping assemblies 2 need to approach each other, control the second motor 304 to rotate to drive the bidirectional threaded rod 301 to rotate, and the two positioning plates 305 move in the direction of approaching each other. At this time, the two positioning plates 305 drive the corresponding two clamping assemblies 2 to move in the direction of approaching each other. When the two clamping assemblies 2 need to move away from each other, control the second motor 304 to rotate in the reverse direction to drive the bidirectional threaded rod 301 to rotate in the reverse direction, and the two positioning plates 305 move in the direction of moving away from each other. At this time, the two positioning plates 305 drive the corresponding two clamping assemblies 2 to move in the direction of moving away from each other.

[0033] Further, the second power driving assembly 4 further includes a driving gear 402. The driving gear 402 is rotatably matched with the corresponding U-shaped frame 104. The driving gear 402 is meshed with the driving rack 401. A third motor 403 is installed on the surface of the U-shaped frame 104 near the driving gear 402. The output end of the third motor 403 is fixedly connected to the driving gear 402. As Figure 1 shown, in the initial state, the moving frame 302 is at the rightmost side. When the moving frame 302 needs to move to the left, drive the third motor 403 to drive the driving gear 402 to rotate. The driving rack 401 moves to the left to drive the moving frame 302 to move to the left. When the moving frame 302 needs to move to the right, drive the third motor 403 to rotate in the reverse direction to drive the driving gear 402 to rotate in the reverse direction. The driving rack 401 moves to the right to drive the moving frame 302 to move to the right.

[0034] The operation process of this embodiment is as follows: In the initial state, the two clamping plates 201 within the same clamping assembly 2 are farthest apart, and the elastic resetting member is compressed. When the clamping plate 201 is on the circumferential side of the spur gear, the two cylinders 206 are controlled simultaneously to drive the corresponding ear plates 205 to move. The push-pull inclined plate 204 moves to drive the corresponding linkage inclined plate 203 to move. Under the action of the elastic resetting member, the corresponding two clamping plates 201 move towards each other. At this time, the two clamping plates 201 clamp the bearing of the corresponding spur gear. When the spur gear needs to be unclamped, the two cylinders 206 are controlled to drive the corresponding ear plates 205 to move in the reverse direction. The push-pull inclined plate 204 moves in the reverse direction to push the corresponding linkage inclined plate 203, and the elastic resetting member is compressed. Under the thrust, the corresponding two clamping plates 201 move away from each other. At this time, the clamping of the spur gear can be released.
