Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to an automatic full inspection machine for internal holes. Background Technology

[0002] The internal diameter of a part requires separate inspection using a go gauge and a no-go gauge. If the go gauge passes through the internal diameter while the no-go gauge does not, the internal diameter of the part is considered acceptable. In existing technology, go gauge inspection and no-go gauge inspection are two separate processes, resulting in lower inspection efficiency. To address these technical problems, this invention proposes a new solution that automatically completes both go gauge and no-go gauge inspections in a single loading operation, thereby improving inspection efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic full inspection machine for internal holes, which aims to solve the technical problem of relatively low efficiency in the internal hole inspection of parts in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic full inspection internal hole machine includes a frame and a vibratory feeder. The frame is equipped with a turntable and a turntable drive device. A tray is provided at the bottom of the turntable and the tray does not rotate relative to the frame. Multiple receiving holes are evenly spaced along the circumference of the turntable. A guide pipe is provided between the discharge chute of the vibratory feeder and the turntable, and the outlet end of the guide pipe corresponds to a receiving hole. A go gauge assembly and a no-go gauge assembly are provided on the frame, and each of the go gauge assembly and no-go gauge assembly corresponds to a receiving hole.

[0006] Furthermore, the frame of the automatic full inspection internal hole machine is provided with a good product unloading chute, which is located below a receiving hole; the tray is provided with a clearance opening corresponding to the good product unloading chute.

[0007] Furthermore, the frame of the automatic full inspection internal hole machine is equipped with a first-stage product collection device and a second-stage product collection device, each corresponding to a receiving hole; the first-stage product collection device is located between the go gauge assembly and the no-go gauge assembly; the second-stage product collection device is located upstream of the discharge chute.

[0008] Furthermore, the first-stage product collection device includes a first baffle block, a first baffle block drive cylinder, and a first-stage product receiving box; the second-stage product collection device includes a second baffle block, a second baffle block drive cylinder, and a second-stage product receiving box; the first baffle block and the second baffle block are respectively located below the corresponding receiving hole.

[0009] Furthermore, an auxiliary support is provided on the frame, and the go gauge assembly and no-go gauge assembly are mounted on the auxiliary support.

[0010] Furthermore, the go gauge assembly includes a first bracket, a go gauge, and a go gauge drive cylinder, with the go gauge drive cylinder vertically downward mounted on the first bracket.

[0011] Furthermore, the go gauge assembly also includes a first guide seat connected to the auxiliary support, the first guide seat being provided with a first tapered hole; the go gauge can pass through the first tapered hole.

[0012] Furthermore, the stop gauge assembly includes a second bracket, a stop gauge, and a stop gauge drive cylinder, with the stop gauge drive cylinder vertically downward mounted on the second bracket.

[0013] Furthermore, the stop gauge assembly also includes a second guide seat connected to the auxiliary support, the second guide seat being provided with a second tapered hole; the stop gauge can pass through the second tapered hole.

[0033] This utility model provides an automatic full-inspection machine for internal holes. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0034] Please see Figures 1 to 10 This utility model provides an automatic full-inspection internal hole machine. The accompanying drawings are for illustrative purposes only and are not proportional to actual products. The drawings only depict structures relevant to the inventive points of this application; some conventional structures are not specifically shown. Vibratory feeder machines are prior art, and the drawings only show their external structure. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application.

[0035] The automatic full inspection internal hole machine includes a frame 8 and a vibratory feeder 1. A turntable 81 and a turntable drive device are mounted on the frame; a tray 82 (e.g., ...) is mounted at the bottom of the turntable. Figure 6 and Figure 7 As shown), the tray does not rotate relative to the frame; multiple material receiving holes are evenly spaced along the circumference of the turntable. Figure 5 (811, 812, 813, 814, 815 and 816 are all receiving holes); a guide pipe 12 is provided between the discharge chute 11 and the turntable of the vibratory feeder, and the outlet end 122 of the guide pipe corresponds to a receiving hole; a go gauge assembly and a no-go gauge assembly are provided on the frame, and the go gauge assembly and the no-go gauge assembly each correspond to a receiving hole.

[0036] It should be noted that although the go gauge component shown in the attached figure is located upstream of the no-go gauge component, this application is not limited to this. The no-go gauge component can also be set upstream of the go gauge component, because whether the go gauge inspection or the no-go gauge inspection is performed first does not change the essence of this technical solution.

[0037] The aforementioned turntable drive device is used to drive the turntable to rotate. Preferably, the turntable drive device includes a motor 83 and a divider (not shown in the figure), with the output shaft of the divider connected to the turntable. The divider converts the continuous rotation generated by the motor into intermittent rotation, thereby enabling the turntable to rotate a certain angle at regular intervals, transferring the parts in each receiving hole as a whole to the next workstation. The divider itself is prior art, and its structure is not specifically shown in the accompanying drawings.

[0038] To achieve automatic unloading of good parts, the following configuration can be used: a good part unloading trough 6 is provided on the frame, located below a receiving hole (816); a clearance opening is provided on the tray corresponding to the good part unloading trough (not visible from the attached diagram). That is, when a good part in the receiving hole rotates to the top of the unloading trough, the good part will fall directly into the good part unloading trough below through the clearance opening on the tray, thus achieving automatic unloading and avoiding manual removal of the good part. The specific shape of the clearance opening is not limited here, as long as it ensures that the part can fall smoothly from the receiving hole (816).

[0039] In practical applications, the inner diameter of the guide tube is slightly larger than the outer diameter of the part (not shown in the figure) (the axial length of the part is greater than its diameter), allowing each part to smoothly enter the guide tube 12 from the inlet end 121, and ensuring that the axis of the part is approximately in the same direction as the axis of the guide tube after entering. This also ensures that when the part is discharged from the outlet end 121 of the guide tube and falls into the receiving hole, the axis of the part is vertical. Furthermore, because the gap between the guide tube and the side wall of the discharge chute of the vibratory feeder is very small, parts cannot pass through, thus ensuring that parts can only enter the guide tube one at a time.

[0040] In practical applications, it is possible that the internal hole inspection of a part will fail (i.e., the part is defective). To achieve automatic removal of defective parts (instead of manual removal), the following configuration can be implemented: a primary defective part collection device 3 and a secondary defective part collection device 5 are installed on the frame, each corresponding to a receiving hole (813 and 815). The primary defective part collection device is located between the go gauge assembly and the no-go gauge assembly; the secondary defective part collection device is located upstream of the feed chute. In actual use, defective parts that fail the go gauge inspection are discharged into the primary defective part collection device, and defective parts that fail the no-go gauge inspection are discharged into the secondary defective part collection device.

[0041] The primary and secondary part collection devices can take various forms; here, a simple implementation is provided: the primary part collection device includes a first stop block 32, a first stop block drive cylinder 31, and a primary part receiving box 30; the secondary part collection device includes a second stop block 52, a second stop block drive cylinder 51, and a secondary part receiving box 50; the first and second stop blocks are respectively positioned below their corresponding receiving holes (813 and 815). Under normal circumstances, the first and second stop blocks are located below their respective receiving holes to ensure that parts in the receiving holes do not fall out and that the turntable can smoothly deliver parts to the next station when it rotates. When the gauge fails the inspection, the first stop block drive cylinder moves the first stop block away from its corresponding receiving hole, the turntable rotates, and the part that failed the gauge inspection falls from the receiving hole of the primary part collection device into the primary part collection box; then, the first stop block drive cylinder resets the first stop block, placing it below its corresponding receiving hole again. Similarly, when the stop gauge fails the inspection, the second stop block drive cylinder moves the second stop block away from the corresponding receiving hole. The turntable rotates, and the part that failed the stop gauge inspection falls from the corresponding receiving hole of the second part collection device into the second part collection box. Then, the second stop block drive cylinder resets the second stop block, placing it below the corresponding receiving hole again.

[0042] Furthermore, an auxiliary support 88 is provided on the frame, and the go gauge assembly and the no-go gauge assembly are mounted on the auxiliary support. The auxiliary support can be configured as a single unit as shown in the attached figure, or it can be configured as two units (i.e., one auxiliary support for each of the go gauge assembly and the no-go gauge assembly), which is not limited here.

[0043] like Figure 3 and Figure 9 As shown, the go gauge assembly further includes a first bracket 21, a go gauge 25, and a go gauge drive cylinder 22, with the go gauge drive cylinder vertically mounted on the first bracket. The go gauge drive cylinder drives the go gauge to reciprocate vertically to achieve go gauge detection.

[0044] like Figure 9 As shown, to guide the go gauge, the following can be further provided: the go gauge assembly also includes a first guide seat 26 connected to an auxiliary support, the first guide seat having a first tapered hole 26; the go gauge can pass through the first tapered hole. When the bottom of the go gauge is inserted into the first tapered hole, because the tapered hole is larger at the top and smaller at the bottom, it can guide the go gauge, ensuring that the go gauge can pass through the bottom of the tapered hole, thus accurately inserting it into the corresponding part.

[0045] like Figure 3 and Figure 10 As shown, the stop gauge assembly can adopt the same structure, specifically configured as follows: the stop gauge assembly includes a second bracket 41, a stop gauge 45, and a stop gauge drive cylinder 42, with the stop gauge drive cylinder vertically downward mounted on the second bracket.

[0046] Similarly, to guide the stop gauge, the following configuration can be made: the stop gauge assembly also includes a second guide seat 46 connected to an auxiliary support, the second guide seat being provided with a second tapered hole ( Figure 10 The position corresponding to the bottom of the stop gauge; the stop gauge can pass through the second tapered hole.

[0047] Please continue reading. Figure 9 and Figure 10 Furthermore, in order to achieve a buffering effect when driving the go gauge and no-go gauge, the following can be set: the top of the go gauge 25 is connected to a first ejector pin 24, the outer side of the first ejector pin is slidably provided with a first ejector pin sleeve 23, the first ejector pin sleeve is connected to the piston rod 221 of the go gauge driving cylinder, and the top of the first ejector pin is provided with a first spring 29; the top of the no-go gauge 45 is connected to a second ejector pin 44, the outer side of the second ejector pin is slidably provided with a second ejector pin sleeve 43, the second ejector pin sleeve is connected to the piston rod 421 of the no-go gauge driving cylinder, and the top of the second ejector pin is provided with a first spring 49.

[0048] When the piston rod of the go gauge drive cylinder presses down on the first ejector sleeve, the elastic force of the first spring buffers the pressing process of the first ejector and the go gauge, preventing damage to the part being inspected. Similarly, when the piston rod of the no-go gauge drive cylinder presses down on the second ejector sleeve, the elastic force of the second spring also buffers the pressing process of the second ejector and the no-go gauge.

[0049] In practical applications, the pass / fail determination of the go gauge and no-go gauge can be achieved by detecting the vertical movement of the go gauge and no-go gauge. Various methods such as fiber optic sensors, proximity switches, and displacement sensors can be used for detection, and no specific method is specified here.

[0050] To facilitate understanding, the working principle is briefly described below.

[0051] (1) Pour the parts with the inner hole to be tested into the vibratory feeder. The vibratory feeder vibrates so that each part enters the guide tube in sequence.

[0052] (2) The parts are discharged from the end of the guide tube and fall into the corresponding receiving hole.

[0053] (3) The turntable rotates once, and the part reaches the position corresponding to the go gauge assembly. The go gauge drive cylinder drives the go gauge to move vertically downward to perform go gauge inspection on the part; then the go gauge drive cylinder drives the go gauge to reset. If the inspection is qualified, the first stop block drive cylinder does not move; if the inspection is unqualified, the first stop block drive cylinder drives the first stop block to leave the corresponding receiving hole.

[0054] (4) The turntable rotates once, and the part reaches the position corresponding to the first product collection device. If the previous step's gauge inspection fails, the part falls into the first product receiving box; if the previous step's gauge inspection passes, no action is taken.

[0055] (5) The turntable rotates once, and the part is at the position corresponding to the stop gauge assembly. The stop gauge drive cylinder drives the stop gauge to move vertically downward to perform stop gauge inspection on the part; then the stop gauge drive cylinder drives the stop gauge to reset. If the inspection is qualified, the second stop block drive cylinder does not move; if the inspection is unqualified, the second stop block drive cylinder drives the second stop block to leave the corresponding receiving hole.

[0056] (6) The turntable rotates once, and the part reaches the position corresponding to the second part collection device. If the stop gauge check in the previous step fails, the part falls into the second part receiving box; if the stop gauge check in the previous step passes, no action is taken.

[0057] (7) The turntable rotates once, and the part reaches the position corresponding to the good product unloading slot and falls into the good product unloading slot.

[0058] It should be noted that each time the turntable rotates, the parts in each receiving hole simultaneously move to the next station, rather than one part rotating through all stations before the next part is inspected.

[0059] The number of receiving holes is determined by the specific number of workstations. The preferred embodiment of this application includes a vibratory feeder, a go gauge assembly, a first-pass product collection device, a no-pass gauge assembly, a second-pass product collection device, and a good-quality product unloading chute; these correspond to receiving holes 811, 812, 813, 814, 815, and 816, respectively. (See attached...) Figure 5 As can be observed, there are a total of 8 receiving holes, with the other two corresponding to "empty spaces". This design mainly ensures that the spacing between each receiving hole is equal in the circumferential direction and corresponds to each workstation. This application does not limit the receiving holes in the "empty spaces".

[0060] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
