Description

Technical Field

[0001] This utility model relates to the field of meter counters, and in particular to a meter counter with adjustable pressure. Background Technology

[0002] In the automobile production process, a meter counter is used to measure the distance traveled by a moving chain or belt. For chains of different thicknesses or heights, and to adjust the pressure between the meter counter wheel and the chain, it is necessary to replace the meter counter or add shims between the meter counter and the mounting base. This adjustment method is relatively complicated and inefficient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable pressure meter.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An adjustable pressure meter counter includes a mounting frame, a mounting plate, an adjusting plate, a spring, a pull rod, a traveling wheel, a transmission rod, a meter-counting assembly, and a handwheel assembly. The transmission rod is rotatably mounted on the mounting plate and one end is fixedly connected to the traveling wheel. The meter-counting assembly is fixedly mounted on the mounting plate and engages with the other end of the transmission rod. The mounting plate and the adjusting plate are both slidably mounted on the mounting frame. The handwheel assembly is fixedly mounted on the mounting frame and its output part is connected to the adjusting plate. The two ends of the spring respectively abut against the mounting plate and the adjusting plate. The fixed end of the pull rod is connected to the mounting plate, and the limiting end of the pull rod is slidably mounted on the adjusting plate.

[0006] Furthermore, two parallel guide rods are fixedly installed on the mounting bracket, and both the mounting plate and the adjusting plate are slidably mounted on the guide rods.

[0007] Furthermore, two pull rods are provided between the mounting plate and the adjusting plate, and the spring is sleeved on the pull rods.

[0008] Furthermore, a rotating seat is fixedly mounted on the mounting plate, the rotating seat is provided with a rotating hole, and bearings are provided at both ends of the rotating hole. The transmission rod is mounted on the two bearings, and the meter counting component is fixedly mounted on the rotating seat.

[0009] Furthermore, the meter-counting assembly includes an encoder and a coupling. The encoder is fixedly mounted on the rotating base, and the coupling is fixedly mounted inside the encoder and cooperates with the transmission rod.

[0010] Furthermore, the handwheel assembly includes a connecting seat, a position display, a handwheel, and a ball screw.

[0011] Furthermore, the connecting seat is provided with a locking hole that mates with the ball screw, and a locking slider that mates with the locking hole is slidably disposed in the locking hole. The locking slider is threadedly connected to one end of the locking rod, and the locking rod is rotatably disposed on the connecting seat with its other end fixedly connected to the locking wheel.

[0012] Furthermore, the two ends of the mounting plate are fixedly mounted on the first sliding sleeve, and the two ends of the adjusting plate are fixedly mounted on the second sliding sleeve. Both the first sliding sleeve and the second sliding sleeve are slidably mounted on the guide rod.

[0013] Furthermore, a rubber ring is fixedly installed on the outer wall of the walking wheel.

[0014] The beneficial effects of this utility model are:

[0015] 1) In this technology, the contact degree between the traveling wheel and the material being measured can be adjusted arbitrarily by using components such as mounting plate, adjustment plate and handwheel assembly. This allows for better and faster adjustment, improving the efficiency of adjustment. In addition, the spring design is better adapted to uneven measurement surfaces, ensuring that the material is always pressed firmly without slipping, resulting in higher measurement accuracy.

[0016] 2) In this technology, the first and second sliding sleeves serve two purposes: first, to prevent the mounting plate and the adjusting plate from being worn; and second, to guide the mounting plate and the adjusting plate and prevent them from tilting on the guide rod.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See Figures 1-4 This utility model provides a technical solution:

[0024] An adjustable pressure meter counter includes a mounting frame 1, a mounting plate 2, an adjusting plate 3, a spring 4, a pull rod 5, a traveling wheel 6, a transmission rod 7, a meter-counting assembly, and a handwheel assembly. The transmission rod 7 is rotatably mounted on the mounting plate 2, with one end fixedly connected to the traveling wheel 6. The meter-counting assembly is fixedly mounted on the mounting plate 2 and engages with the other end of the transmission rod 7. Both the mounting plate 2 and the adjusting plate 3 are slidably mounted on the mounting frame 1. The handwheel assembly is fixedly mounted on the mounting frame 1, and its output section is connected to the adjusting plate 3. The two ends of the spring 4 abut against the mounting plate 2 and the adjusting plate 3, respectively. The fixed end of the pull rod 5 is connected to the mounting plate 2, and the limiting end of the pull rod 5 is slidably mounted on the adjusting plate 3. A rubber ring 23 is fixedly mounted on the outer wall of the traveling wheel 6. The mounting bracket 1 is fixed to the ground to install the guide rod 8 and the handwheel assembly. The mounting plate 2 is used to install the metering component and the transmission rod 7. The metering component records the number of rotations of the transmission rod 7. The transmission rod 7 rotates synchronously with the traveling wheel 6. The rubber ring 23 on the traveling wheel 6 is designed to allow slight deformation when in contact with the material, preventing rigid contact between the traveling wheel 6 and the material from causing wear. A spring 4 is installed between the mounting plate 2 and the adjusting plate 3, allowing the mounting plate 2 to move up and down to prevent severe bending and deformation of the transmission rod 7. The handwheel assembly controls the distance between the adjusting plate 3 and the material being measured, thereby adjusting the degree of contact between the rubber ring 23 and the material. The pull rod 5 is a screw rod, with a threaded fit between the pull rod 5 and the mounting plate 2, and a sliding fit between the adjusting plate 3 and the pull rod 5. The nut end on the pull rod 5 limits the movement distance between the mounting plate 2 and the adjusting plate 3.

[0025] In some embodiments, two parallel guide rods 8 are fixedly mounted on the mounting frame 1, and the mounting plate 2 and the adjusting plate 3 are slidably mounted on the guide rods 8. Both ends of the mounting plate 2 are fixedly mounted on the first sliding sleeve 21, and both ends of the adjusting plate 3 are fixedly mounted on the second sliding sleeve 22. Both the first sliding sleeve 21 and the second sliding sleeve 22 are slidably mounted on the guide rods 8. The guide rods 8 guide the movement of the mounting plate 2 and the adjusting plate 3. Two sliding grooves can be provided on the mounting frame 1, and both ends of the mounting plate 2 and the adjusting plate 3 can be positioned within these grooves. The first sliding sleeve 21 and the second sliding sleeve 22 serve two purposes: first, to prevent wear on the mounting plate 2 and the adjusting plate 3; and second, to guide the mounting plate 2 and the adjusting plate 3, preventing them from tilting on the guide rods 8.

[0026] In some embodiments, two pull rods 5 are provided between the mounting plate 2 and the adjusting plate 3, and a spring 4 is sleeved on the pull rod 5. The spring 4 is sleeved on the pull rod 5 to prevent it from falling out between the mounting plate 2 and the adjusting plate 3.

[0027] In some embodiments, a rotating seat 9 is fixedly mounted on the mounting plate 2. The rotating seat 9 has a rotating hole 10, and bearings 11 are provided at both ends of the rotating hole 10. The transmission rod 7 is mounted on the two bearings 11, and the meter-counting assembly is fixedly mounted on the rotating seat 9. The rotating seat 9 is fixed to the mounting plate 2 to mount the bearings 11 (as in the prior art). The bearings 11 are used to mount the transmission rod 7, thus reducing friction between the transmission rod 7 and the rotating seat 9 and preventing the transmission rod 7 from failing to rotate due to excessive friction.

[0028] In some embodiments, the meter-counting assembly includes an encoder 12 and a coupling 13. The encoder 12 is fixedly mounted on the rotating base 9, and the coupling 13 is fixedly mounted inside the encoder 12 and cooperates with the transmission rod 7. The encoder 12 is fixed to the rotating base 9 and connected to the coupling 13. The encoder 12 is a prior art module. The encoder 12 is used to measure the number of rotations of the transmission rod 7 and calculates the distance traveled by the rubber ring 23.

[0029] In some embodiments, the handwheel assembly includes a connecting seat 14, a position display 15, a handwheel 16, and a ball screw 17. The connecting seat 14 is fixedly mounted on the mounting bracket 1, the position display 15 is fixedly mounted on the connecting seat 14, and the ball screw 17 is rotatably mounted on the position display 15. The handwheel 16 is fixedly mounted on the upper end of the ball screw 17, and the lower end of the ball screw 17 is threadedly engaged with the adjusting plate 3. The connecting seat 14 is fixed on the mounting bracket 1 to mount the position display 15. The position display 15 cooperates with the connecting seat 14 to mount the ball screw 17. The ball screw 17 can only rotate on the position display 15 and cannot move up or down. The handwheel 16 is used to manually control the rotation of the ball screw 17. The ball screw 17 is threadedly connected to the adjusting plate 3, thereby driving the adjusting plate 3 to move up and down. The mounting bracket 1 is provided with a through hole that mates with the ball screw 17.

[0030] In some embodiments, the connecting seat 14 is provided with a locking hole that mates with the ball screw 17. A locking slider 18 that mates with the locking hole is slidably disposed in the locking hole. The locking slider 18 is threadedly connected to one end of the locking rod 19. The locking rod 19 is rotatably disposed on the connecting seat 14 and its other end is fixedly connected to the locking wheel 20. The locking hole is used to install the locking slider 18, which has a locking ramp. The locking wheel 20 is a knob; when the locking wheel 20 rotates, it drives the locking rod 19 to rotate. The locking rod 19 and the locking slider 18 are threadedly engaged. After the locking slider 18 slides, its locking ramp presses against the ball screw 17, effectively preventing the ball screw 17 from rotating freely.
