Description

Technical Field

[0002] Plastic is plastic. Plastic is widely used and is an indispensable component in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. As my country's economy has achieved sustained and stable growth, industries such as home appliances, automobiles, mobile phones, PCs, and medical devices have benefited from a good external environment and have also achieved rapid development. Therefore, the demand for plastic parts has also increased significantly. Plastic parts need to be quality inspected before leaving the factory, including size inspection, to select products with unqualified sizes. Therefore, we have launched a high-precision plastic parts size detection device.

The high-precision dimension measuring instrument, through the provided placement component, can make it more convenient for operators to measure the dimensions of irregularly shaped objects and avoid the irregularly shaped objects from tipping over or rolling during the measurement process.

Although some existing plastic detection devices fix the plastic parts, they need to wait for the previous plastic part to be detected before removing it from the detection platform, and then place the next plastic part to be measured in the detection area and fix it for detection. The efficiency is very low and needs to be further improved. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a high-precision plastic part size detection device, including a base 1, an intermittent rotating component 2 and four supporting columns 3 are respectively provided in the middle of the top of the base 1, a detection platform 4 is provided on the top of the intermittent rotating component 2, and a fixing component 5 is provided on the top surface of the detection platform 4, a mounting platform 6 is fixedly connected between the top ends of the four supporting columns 3, a fixing cylinder 7 is fixedly connected to the top of the mounting platform 6, a gantry 8 is fixedly connected to the edge of the top surface of the base 1, a detection head 9 is provided on the bottom surface of the top plate of the gantry 8, and two sets of arc-shaped racks 10 are provided on the outer top end of the fixing cylinder 7.

[0025] In this embodiment, Figure 3 and Figure 4As shown, the intermittent rotating assembly 2 includes a motor 201 fixedly connected to the top of the base 1, and the output end of the motor 201 is fixedly connected with a rotating disk 202 and a residual gear 203 from bottom to top in sequence, the residual gear 203, the residual gear 203 is a quarter gear, a fan-shaped groove is opened on one side of the rotating disk 202, and the fan-shaped groove is located directly above the tooth groove of the residual gear 203, the outer side of the rotating disk 202 is fitted with the outer side of the limiting disk 204, and a support shaft 205 runs through the middle of the limiting disk 204, and the top of the support shaft 205 is fixedly connected with a driven gear 206, and the support shaft 205 is rotatably connected to the top surface of the base 1, and the limiting The outer side of the disk 204 is provided with four arc grooves, and the curvature of the four arc grooves is consistent with the curvature of the outer side of the rotating disk 202. The driven gear 206 and the residual gear 203 are meshed with each other. The top surface of the detection platform 4 is fixedly connected with four L rods 401. The top ends of the four L rods 401 are fixedly connected through a transmission shaft 402. The bottom end of the transmission shaft 402 is fixedly connected to the middle of the top surface of the driven gear 206. A circular hole 403 is opened in the middle of the detection platform 4. The fixed cylinder 7 passes through the middle of the circular hole 403, and the outer wall of the fixed cylinder 7 does not contact the inner wall of the circular hole 403. The middle of the fixed cylinder 7 passes through the inner wall of the circular hole 403. The transmission shaft 402 is passed through; the motor 201 drives the residual gear 203 and the rotating disk 202 to rotate at the same time. Since the transmission ratio of the residual gear 203 and the driven gear 206 is consistent, and the residual gear 203 is a quarter gear, when the residual gear 203 rotates one circle, the driven gear 206 rotates a quarter turn, and the driven gear 206 drives the upper detection platform 4 to rotate a quarter turn, and the plastic parts fixed by the four groups of clamping plates 504 are rotated to the bottom of the detection head 9 in turn for size detection. This structure makes the detection of plastic parts more coherent, and omits the waiting time for the previous plastic to be detected compared with the traditional detection device. After the part inspection is completed, it is removed from the inspection platform 4, and then the next plastic part to be measured is placed in the inspection area and fixed for inspection, thereby improving the inspection efficiency of the plastic parts. Note that during the rotation of the driven gear 206, when the residual gear 203 just meshes with the driven gear 206, the rotating disk 202 just disengages from the limit disk 204, and when the residual gear 203 just disengages from the driven gear 206, the arc surface of the rotating disk 202 just re-fits with the arc groove of the limit disk 204. This structure effectively prevents the support shaft 205 from rotating when the residual gear 203 disengages from the driven gear 206.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the fixing assembly 5 includes a single gear 501 and a double gear 502 which are rotatably connected to the top surface of the detection platform 4 through respective connecting shafts, the single gear 501 is meshed with the gear at the lower middle part of the double gear 502, the single gear 501 and the arc-shaped rack 10 are located in the same plane, and the single gear 501 and the arc-shaped rack 10 can mesh with each other, the upper gear in the double gear 502 is meshed with two spur racks 503, one end of the two spur racks 503 is respectively fixedly connected with a clamping plate 504, and the clamping plate 504 The guide rod 505 is slidably connected to the outside of the guide rod 505. Two fixing plates 506 are fixedly connected at both ends of the guide rod 505. The bottom surfaces of the two fixing plates 506 are welded to the top surface of the detection platform 4. A spring 507 is fixedly connected between the two fixing plates 506 and the clamping plate 504. Under the action of the intermittent rotating component 2, the fixing component 5 will rotate with the detection platform 4, and only rotate a quarter of a circle each time. When the single gear 501 in the fixing component 5 rotates to the position of the arc-shaped rack 10, the single gear 501 and the arc-shaped rack 10 are rotated. The arc-shaped racks 10 mesh with each other, the single gear 501 rotates and drives the double gear 502 to rotate in the opposite direction, and the gear located on the upper side of the double gear 502 drives the two spur racks 503 to move away from each other. The spur racks 503 move away from each other, which drives the clamping plates 504 connected thereto to move away from each other. At the same time, the clamping plates 504 squeeze the spring 507. At this time, the two clamping plates 504 release the fixation on the plastic part, and the plastic part can be taken out. Because there are two arc-shaped racks 10, at the same time, the other set of clamping plates 504 also moves away from each other. The two clamping plates 504 are opened away from each other, and a new plastic part to be measured can be placed in. Then, the detection platform 4 continues to rotate a quarter of a turn. After the single gear 501 is disengaged from the arc rack 10, the two clamping plates 504 are reset under the action of the spring 507, and the plastic part is clamped and fixed again. The whole process does not require manual opening and closing of the clamping plates 504, which ensures the detection efficiency while completing the fixation of the plastic part, avoids the deviation of the detection accuracy caused by the displacement of the plastic part during the detection process, and ensures the accuracy of the detection result.

[0027] The use method and advantages of the utility model: When the high-precision plastic part size detection device is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the intermittent rotating component 2 drives the detection platform 4 to rotate a quarter of a turn, and the plastic parts fixed by the four groups of clamping plates 504 are rotated to the bottom of the detection head 9 in turn for size detection. Compared with the traditional detection device, the steps of waiting for the previous plastic part to be detected, removing it from the detection platform 4, and then placing the next plastic part to be measured in the detection area and fixing it for detection are omitted, thereby improving the detection efficiency of plastic parts. Through the mutual cooperation of the intermittent rotating component 2 and the fixing component 5, the clamping plate 504 is automatically opened and closed periodically during the rotation of the detection platform 4, ensuring the detection efficiency while completing the fixation of the plastic parts, avoiding the displacement of the plastic parts during the detection process and causing deviations in the detection accuracy, so that the accuracy of the detection results is guaranteed.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
