Description

Technical Field

[0001] The utility model relates to the technical field of electronic scale calibration, in particular to an electronic scale verification and calibration device. Background Art

[0002] Electronic scales are mainly composed of three parts: load-bearing system, force conversion system and indication system. If the electronic scale has a large weighing error during use, it needs to be calibrated. Some factories will regularly calibrate the electronic scale to ensure the accuracy of material measurement. At present, the calibration of electronic scales is mainly completed by applying standard weights to the center and four corners of the scale. The weights used are usually 1 / 10 of the maximum weighing capacity of the electronic scale. Electronic platform scales are more common electronic scales, and their range is usually larger. For example, the maximum range of an electronic platform scale is 150 kg, and the weight used for calibration is 15 kg. Since this type of weight is heavier, the most commonly used weights are lock-shaped weights.

[0003] However, in the current process of calibrating electronic platform scales, the locking weights are basically picked up and placed by manpower. Since the locking weights are heavy, the physical strength of the relevant personnel is relatively high. Especially when some factories calibrate batches of electronic platform scales, the relevant personnel will have strong hand fatigue due to repeated picking up and placing of the locking weights. It is very easy for the locking weights to slip out of their hands during picking up, posing a safety hazard.

[0004] Therefore, it is necessary to provide a new electronic scale verification and calibration device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

The electronic scale verification and calibration device includes: five locking weights, and also includes two slide rails 1, the two slide rails 1 are slidably sleeved with slide seats 2, the tops of the two slide seats 2 are fixedly installed with two guide slide posts 3, the four guide slide posts 3 are distributed in a rectangular array, the four guide slide posts 3 are slidably sleeved with the same placement plate 4, the tops of the four guide slide posts 3 are fixedly installed with limited end plates, five placement openings are opened on the placement plate 4, the five locking weights are respectively located in the five placement openings, and five placement areas are provided on the placement plate 4. In the initial state, the five locking weights are placed in the corresponding placement areas, the tops of the two slide rails 1 are rotatably installed with first hydraulic cylinders 5, the output shafts of the two first hydraulic cylinders 5 are rotatably connected to the placement plate 4, four fixed seats 6 are fixedly installed on the top of the placement plate 4, the same sliding mounting frame 7 is slidably installed on the four fixed seats 6, five carrying plates 8 are fixedly installed on the sliding mounting frame 7, the five carrying plates 8 respectively pass through the bottom of the handles of the five locking weights to support the five locking weights, and the sliding mounting frame 7 is fixedly installed with Two fixed blocks 9, two second hydraulic cylinders 10 are fixedly installed on the top of the placement plate 4, and the output shafts of the two second hydraulic cylinders 10 are fixedly connected to the two fixed blocks 9 respectively. The sliding mounting frame 7 is pushed to move by the two second hydraulic cylinders 10, so that the five carrying plates 8 can pass through the corresponding locking weights. The same connecting seat 11 is fixedly installed on the top of the two slide rails 1, and two third hydraulic cylinders 12 are fixedly installed on the outer wall of the connecting seat 11 on one side close to the placement plate 4. The output shafts of the two third hydraulic cylinders 12 are fixedly connected to the two slide seats 2 respectively. The same supporting platform 13 is fixedly installed between the two slide rails 1. In the initial state, the placement plate 4 is located directly above the supporting platform 13. After the locking weight is placed into the placement port, the locking weight is initially supported by the supporting platform 13, and then the output shafts of the two second hydraulic cylinders 10 are started to retract, so that the five carrying plates 8 pass through the corresponding weights, and then the output shafts of the two third hydraulic cylinders 12 are started to extend, and the two slide seats 2 are pushed forward until the placement plate 4 is directly above the weighing platform of the tray of the electronic platform scale. At this time, Figure 1 As shown, the locking weight is separated from the support platform 13 and supported by the support plate 8.

[0022] In this embodiment, in order to reduce the friction of the locking weight, a plurality of round rods 14 are rotatably mounted on the top of the support platform 13, and the plurality of round rods 14 are arranged at equal intervals.

[0023] In this embodiment, in order to increase the support reliability of the sliding mounting frame 7, two auxiliary support slide bars are fixedly installed on the top of the placement plate 4. The two auxiliary support slide bars both penetrate the sliding mounting frame 7 and are slidably connected to the sliding mounting frame 7.

[0024] In this embodiment, in order to increase the supporting reliability of the support plate 8 for the locking weight, five auxiliary support blocks 15 are fixedly installed on the top of the placement plate 4. The top of the auxiliary support block 15 is located in the same horizontal plane as the bottom of the support plate 8. After the support plate 8 passes through the locking weight, its bottom is placed on the auxiliary support block 15.

[0025] In this embodiment, in order to allow the carrying plate 8 to be smoothly placed on the auxiliary support block 15, the connection between the outer wall of the side of the carrying plate 8 away from the sliding mounting frame 7 and the bottom is designed with a rounded corner, and a positioning block is integrally formed on the top of the auxiliary support block 15. When the carrying plate 8 conflicts with the positioning block, the second hydraulic cylinder 10 stops running.

[0026] The working principle of the electronic scale verification and calibration device provided by the utility model is as follows:

[0027] In the initial state, the placement plate 4 is located directly above the support platform 13, and the five lock-shaped weights are all located in the corresponding placement areas;

[0028] When calibrating the electronic platform scale, the corresponding locking weights are placed in the corresponding placement openings according to the calibration needs. For example, when locking weights need to be placed at the four corners of the weighing platform of the electronic platform scale, the locking weight in the middle position remains stationary, and the other four locking weights are placed in the corresponding placement openings. For example, when locking weights need to be placed at the center of the weighing platform of the electronic platform scale, the locking weight in the middle position is placed in the corresponding placement opening, and the other four locking weights remain stationary. If locking weights need to be placed at the four corners and the center of the weighing platform of the electronic platform scale, then all five locking weights are placed in the corresponding placement openings. Here, take the case where all five locking weights are put into use as an example: first move the electronic platform scale between the two slide rails 1 and adjust the position, then place the five locking weights in the corresponding placement openings in turn, then start the output shafts of the two second hydraulic cylinders 10 to retract, the two second hydraulic cylinders 10 drive the sliding mounting frame 7 to move to the left, and the sliding mounting frame 7 drives the carrier plate 8 to move, so that The carrying plate 8 passes under the handle of the locking weight. When the carrying plate 8 conflicts with the positioning block on the auxiliary support block 15, the two second hydraulic cylinders 10 are closed, and then the output shafts of the two third hydraulic cylinders 12 are started to extend forward. The two third hydraulic cylinders 12 push the two slides 2 to slide forward. As the slides 2 move, the placement plate 4 will run to the top of the weighing platform of the electronic platform scale. Since the carrying plate 8 supports the locking weight, it will not fall after leaving the support platform 13. Then, the output shafts of the two first hydraulic cylinders 5 are started to retract, driving the placement plate 4 to slide downward. As the placement plate 4 continues to move downward, the five locking weights will slowly fall on the weighing platform, respectively at the four corners and the center of the weighing platform. Thereafter, the output shafts of the two second hydraulic cylinders 10 are started to extend, driving the sliding mounting frame 7 to move to the right, then all the carrying plates 8 will be pulled out from the corresponding locking weights and finally reset, and finally the output shafts of the two first hydraulic cylinders 5 are started to extend, driving the placement plate 4 to rise to a high position.

[0029] After completing the above work, the electronic platform scale can be calibrated. After completing the calibration of the first electronic platform scale, the placement plate 4 can be moved down first, and then the supporting plate 8 can be passed through the locking weight. After that, the placement plate 4 can be lifted to make the locking weight leave the electronic platform scale, and then the output shafts of the two third hydraulic cylinders 12 can be retracted to make the placement plate 4 retreat to the initial position. The locking weight is still supported by the support platform 13. When calibrating subsequent electronic platform scales, there is no need to manually place the locking weight into the placement port. After all electronic platform scales are calibrated, the locking weight can be taken out and placed in the corresponding placement area.
