However, in the process of transferring the fixture from the storage location to the slide rail, the applicant found that the traditional method of using robots has high transportation costs, and the robot will occupy a large space, resulting in low utilization of the factory space. Utility Model Content
[0003] The utility model aims to provide a multi-stock location fixture switching traction mechanism to solve the problem that the method of using a robot to transfer the fixture from the stock location to the slide rail is high in cost and leads to low utilization rate of the plant space.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The traction mechanism for switching multi-position clamps includes a traction motor slidably installed on the storage position, a traction wheel fixed on the clamp, and a traction hook fixed on the traction motor for hooking the traction wheel. It also includes support guide wheels rotatably arranged on both sides of the storage position and a limit wheel arranged on one side of the support guide wheel and capable of rolling along the side of the clamp.

The traction motor is connected to a reducer, and the reducer is connected to a traction gear. A rack is fixed on the storage position, and the traction gear is meshed with the rack. The traction gear rolls along the rack to drive the traction motor and the reducer to slide axially along the storage position.

[0007] Preferably, as an improvement, a positioning pin seat is provided at one end of the storage position away from the slide rail, a positioning pin is inserted into the positioning pin seat, the reducer is connected to a positioning hole plate, a positioning seat is provided on the storage position, and a positioning hole that can be connected to the positioning hole plate is opened on the positioning seat.
[0008] Preferably, as an improvement, the traction hook comprises a hook body, a hook groove is provided on the hook body, and two ends of the hook groove penetrate the hook body along the axial direction of the slide rail.
[0009] Preferably, as an improvement, guiding inclined surfaces are provided on the inner walls at both ends of the hook groove so that the two ends of the hook groove form a flared shape.
[0010] Preferably, as an improvement, a guide rail is provided on the storage position, the reducer is connected to a mounting seat, and the mounting seat is slidably connected to the guide rail via a slider.
[0011] Preferably, as an improvement, L-shaped protective side panels are provided on both sides of the guide rail, and a protective top panel is provided above the rack.
[0012] The principles and beneficial effects of this scheme are:
[0013] 1. In this solution, a traction motor is slidably arranged on the storage location, and a traction hook is arranged. When the fixture is transported from the processing location to the storage location along the slide rail, the traction hook hooks the traction wheel on the fixture, and drives the traction gear to roll along the rack to drive the traction motor and the traction hook to slide along the axial direction of the storage location as a whole, thereby pulling the fixture to the storage location, so that the fixture is mounted on the support guide wheel. The rotating support guide wheel allows the fixture to be easily pulled into the storage location, so that the fixture can be put into storage. Similarly, the traction motor and the traction hook can be driven to slide in the opposite direction on the storage location by the reverse rotation of the traction gear and the reverse rolling along the rack, so that the fixture in the storage location can be pushed onto the slide rail, so that the fixture can be taken out of storage. In this solution, a traction mechanism composed of a traction motor, a traction hook, a support guide wheel, a traction gear and a rack is directly integrated on the storage location to pull the fixture, so that the fixture moves directly along the storage location to realize the storage and out of storage of the fixture. Compared with the robot grabbing and transporting the fixture, the structure of this solution is simpler, and this solution is integrated on the storage location without occupying additional ground space.
[0014] 2. Setting the support guide wheel can replace the sliding friction between the fixture and the storage position with the rolling friction between the fixture and the support guide wheel, which can make the fixture easier to enter and exit the warehouse, reduce the resistance of the fixture entering and exiting the warehouse, thereby reducing the resistance of components such as the traction motor, traction gear and rack, and can effectively extend the service life of related components, thereby extending the service life of the equipment, reducing the frequency of equipment maintenance and replacement, and saving costs.
[0015] 3. The traction motor is driven to slide by using a traction gear and a rack. Compared with driving by an electrode screw, the structure of the traction gear and the rack is simpler, and the processing difficulty, processing cost and maintenance cost are lower.
[0016] 4. This solution sets a deceleration switch for entering the warehouse, a switch for entering the warehouse in place, a deceleration switch for leaving the warehouse, and a switch for leaving the warehouse in place on the warehouse position, which can make the fixture slow down and move into place when entering the warehouse in place and when leaving the warehouse in place, avoid sudden stops, and ensure the stability of the equipment. Specifically, when leaving the warehouse, when the switch touch plate triggers the deceleration switch for leaving the warehouse, the controller controls the traction motor to decelerate, and the traction motor decelerates slowly until the switch for leaving the warehouse in place is triggered and stops; similarly, when entering the warehouse, when the switch touch plate triggers the deceleration switch for entering the warehouse, the controller controls the traction motor to decelerate, and the traction motor decelerates slowly until the switch for entering the warehouse in place is triggered and stops. In addition, this solution also sets an anti-overtravel switch. When the anti-overtravel switch is triggered, the controller controls the alarm to sound, thereby achieving the function of preventing the fixture from overtravel.
[0017] 5. This solution sets up structures such as positioning pin seats, positioning pins, positioning hole plates, and positioning seats on the storage position. The positioning pins are inserted in the positioning pin seats during daily operation of the equipment. When the equipment is being repaired, the traction motor is in the storage state, the positioning holes on the positioning hole plate and the positioning seat are aligned, and the positioning pins are inserted into the positioning hole plate and the positioning holes to achieve the positioning of the traction motor, which can prevent the maintenance personnel from operating the traction motor incorrectly during the maintenance process and causing the traction motor to run.
[0018] 6. In this solution, the hook groove runs through the hook body along the axis direction of the slide rail, so that when the fixture is transported to the storage location, the traction wheel on the fixture can be inserted into the traction hook, and the traction wheel can be hooked without the need for additional movement of the traction hook. The two sides of the hook groove are expanded, so that the traction wheel can be smoothly inserted into the traction hook even if the fixture is slightly offset.
[0019] 7. Setting protective side plates on both sides of the guide rail can protect the side and top surfaces of the guide rail to prevent impurities from falling onto the guide rail and affecting the sliding of the slider; similarly, setting a protective top plate above the rack can also prevent impurities from falling into the tooth groove and affecting the rolling of the gear.

The limiting wheel 41 can roll along the side of the clamp 1 to limit the two sides of the clamp 1.
[0030] A switch touch plate 51 is bolted to one side of the mounting seat 46. The switch touch plate 51 is arranged along the axial direction of the storage position 3 and the front and rear ends of the switch touch plate 51 are integrally formed with an upward section. A deceleration switch for outgoing storage and a switch for outgoing storage in position are installed on the side of one end of the storage position 3 close to the slide rail, and a deceleration switch for entering storage 5 and a switch for entering storage in position 52 are installed on the side of the other end of the storage position 3.

[0031] A locating pin seat 62 is bolted to one end of the storage position 3 away from the slide rail, a locating pin 63 is inserted into the locating pin seat 62, a locating hole plate 6 is bolted to the mounting seat 46, a locating seat 61 is bolted to one side of the locating pin seat 62, and a locating hole that can be communicated with the locating hole plate 6 is opened on the locating seat 61.
[0032] The working principle of this embodiment is:
[0033] When fixture 1 is put into storage, fixture 1 is transported along the slide rail to the storage location 3 ( Figure 2 The traction motor 4 is located at the entrance of the storage position 3, and the traction hook 43 is located on the right side of the fixture 1. When the fixture 1 reaches the entrance of the storage position 3, the traction wheel 2 on it can directly be inserted into the hook groove 432 on the traction hook 43 from the front side end of the hook groove 432, so as to achieve the docking of the traction hook 43 and the traction wheel 2. Then the traction motor 4 drives the traction gear to rotate, and the traction gear rolls along the rack 42 to the left end of the storage position 3, thereby driving the traction motor 4 to slide from the right end to the left end of the storage position 3, thereby pulling the fixture 1 into the storage position 3 to achieve the storage of the fixture 1. In the process of the fixture 1 moving from right to left on the storage position 3, the fixture 1 is mounted on the support guide wheel 40 and the support guide wheel 40 is forced to rotate by friction, so that the storage of the fixture 1 is easier. In the process of storage, the limit wheel 41 rolls along the side of the fixture 1, which can limit and guide the fixture 1, thereby improving the storage stability of the fixture 1.
[0034] When the fixture 1 is about to enter the warehouse, the switch touch plate 51 pushes the warehouse deceleration switch 5 to swing, and the warehouse deceleration switch 5 is triggered. The warehouse deceleration switch 5 sends a signal to the controller, and the controller controls the traction motor 4 to decelerate, so that the traction motor 4 decelerates and runs. When the traction motor 4 continues to run until the switch touch plate 51 pushes the warehouse entry switch 52, the warehouse entry switch 52 is triggered, and the warehouse entry switch 52 sends a signal to the controller, and the controller controls the traction motor 4 to stop running, and the fixture 1 is put into the warehouse. If the traction motor 4 continues to run unexpectedly, the switch touch plate 51 will push the anti-overtravel switch 53, and the anti-overtravel switch 53 will be triggered. The anti-overtravel switch 53 sends a signal to the controller, and the controller controls the alarm to sound an alarm, reminding the operator that the traction motor 4 is overtravel.
[0035] When the clamp 1 is taken out of the warehouse, the traction motor 4 drives the traction gear to rotate in the opposite direction, so that the traction gear rolls along the rack 42 from the left end to the right end of the rack 42, thereby driving the traction motor 4 to slide from the left end to the right end of the storage position 3, and then pushing the clamp 1 hooked on the traction hook 43 from the storage position 3 to the slide rail, completing the removal of the clamp 1 from the warehouse.
[0036] When the clamp 1 is about to be in place for outbound delivery, the switch touch plate 51 pushes the outbound delivery deceleration switch to swing, and the outbound delivery deceleration switch is triggered. The outbound delivery deceleration switch sends a signal to the controller, and the controller controls the traction motor 4 to decelerate, so that the traction motor 4 decelerates and runs. When the traction motor 4 continues to run until the switch touch plate 51 pushes the outbound delivery switch, the outbound delivery switch is triggered, and the outbound delivery switch sends a signal to the controller. The controller controls the traction motor 4 to stop running, and the clamp 1 is completed out of the warehouse.
