Description

Technical Field

[0001] The utility model relates to the technical field of tubular workpiece detection, in particular to a feeding device for tubular workpiece detection. Background Art

[0002] Chinese Patent with application number 202110165889.9 discloses a pipe fitting conveying and inspecting device, which includes a feeding mechanism arranged on a frame, a clamping mechanism installed on a transplanting mechanism, and a detecting mechanism; the detecting mechanism includes a measuring component, a support seat arranged on the top surface of the frame, and a driving component arranged below the support seat; a plurality of bearing grooves for bearing pipe fittings are arranged on the support seat along the length direction of the support seat; the feeding mechanism includes a feeding conveyor belt installed on the frame and a stop block arranged at the end of the feeding conveyor belt, and an induction sensor for sensing the presence or absence of pipe fittings is arranged at the end of the feeding conveyor belt; the clamping mechanism includes a clamping cylinder fixed on a mounting plate for clamping the pipe fitting from the feeding mechanism to the support seat and a clamping jaw connected to the driving end of the clamping cylinder.

[0003] The device of the above solution uses a clamping jaw assembly for feeding. When the feeding conveyor belt moves the tubular workpiece to be inspected to the stop block, after the induction sensor senses the pipe fitting, the clamping jaw will descend, and then the clamping jaw will clamp the tubular workpiece to be inspected. The clamping jaw rises and translates to above the bearing groove of the support seat, and then the clamping jaw descends and releases the tubular workpiece to be inspected to achieve feeding. Finally, the clamping jaw resets and moves above the end of the feeding conveyor belt again.

[0004] In industrial production, in order to reduce costs, single-stroke cylinders are usually used. After each movement of the clamping jaw by the cylinder, there will be a pause for a certain period of time. The steps required to feed the tubular workpiece to be inspected to the bearing groove of the support seat in the above solution are more, resulting in each tubular workpiece to be inspected taking more than ten seconds (the pause duration after the accumulation of multiple actions and the duration of the clamping jaw movement) to move to the bearing groove of the support seat, thus affecting the detection efficiency of the entire detection production line, and the detection efficiency is low.

[0005] Moreover, the handling component where the support seat is located and the clamping jaw component cannot be used synchronously. When the handling component stops working and fully resets, the next tubular workpiece can be moved to the support seat, which will further reduce the detection efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to provide a feeding device for tubular workpiece detection that can improve the detection efficiency without waiting for the feeding of the tubular workpiece to be inspected.

[0007] To achieve the above object, the utility model discloses a feeding device for detecting tubular workpieces, which includes a first bearing block located at the feeding station and several second bearing blocks located at the detection station. Both the first bearing block and the second bearing block are provided with upward-opening support grooves. The first bearing block and the second bearing block are arranged side by side. The first bearing block and the second bearing block are equipped with a moving mechanism. The moving mechanism includes at least two extending parts arranged side by side and used to extend into the support grooves and a driving component used to realize the lifting and translation of the extending parts. The extending direction of the extending parts is parallel to the extending direction of the support grooves. The support groove of the first bearing block penetrates both ends of the first bearing block. The two ends of the support groove of the first bearing block are respectively used to connect the discharge end of the feeding mechanism and to allow the extending parts to extend into. The feeding mechanism has a feeding groove that is the same as and docks with the extending direction of the support groove of the first bearing block.

[0008] When it is necessary to move the tubular workpiece to be detected to the detection station, the tubular workpiece to be detected first enters the support groove of the first bearing block along the feeding groove under the action of the feeding mechanism. Subsequently, the first extending part of the moving mechanism extends into the tubular workpiece to be detected or between the wall of the support groove and the outer wall of the tubular workpiece to be detected under the action of the driving component. The first extending part that extends into the support groove rises under the action of the driving component and jacks up the tubular workpiece to be detected located at the support groove. Subsequently, the first extending part moves horizontally to a set position under the action of the driving component and then moves downward. After the tubular workpiece to be detected moves to the set position, the first extending part withdraws from the tubular workpiece to be detected to complete the feeding of one tubular workpiece to be detected.

[0009] Among them, after the first tubular workpiece to be detected is jacked up by the first extending part, since there is no workpiece blocking on the side of the end of the first bearing block, the next tubular workpiece to be detected located in the feeding groove of the feeding mechanism can directly enter the support groove of the first bearing block under the action of the feeding mechanism.

[0010] When the first tubular workpiece to be detected is moved to the second bearing block at the detection station, the first extending part moves horizontally to the axial side of the support groove of the first bearing block under the action of the driving component, so as to complete the reset. Immediately afterwards, the first extending part moves forward under the action of the driving component to be used for lifting the second tubular workpiece to be detected; at the same time, the second extending part located side by side extends to be used for lifting the first tubular workpiece to be detected. Repeat the above actions to move the second tubular workpiece to be detected to the detection station and move the tubular workpiece to be detected at the detection station to the next station.

[0011] The utility model realizes the movement of the tubular workpiece from the first bearing block to the second bearing table and the movement of the tubular workpiece at the detection station through one moving mechanism, instead of relying on two moving mechanisms as mentioned in the background art. It not only cancels the setting of one moving mechanism, but also can perform the moving action steps required by one moving mechanism in production, without waiting for the feeding of the tubular workpiece to be detected, thus improving the detection efficiency.

[0012] Since the feeding mechanism has a feeding groove for docking with the support groove of the first bearing block, that is, when the previous tubular workpiece to be detected moves away from the support groove, because there is no tubular workpiece to be detected blocking the end side of the first bearing block, the next tubular workpiece to be detected in the feeding groove of the feeding mechanism can directly enter the support groove under the action of the feeding mechanism, so as to realize continuous feeding. After moving the tubular workpiece to be detected on the first bearing block to the detection station, there is no need to wait for feeding, and the movement of the next tubular workpiece to be detected can be carried out immediately, thus realizing the continuous movement of the tubular workpiece to be detected at the feeding and detection stations. Therefore, there is no need to adopt an additional moving mechanism to move the tubular workpiece to be detected onto the first bearing block.

[0013] At the same time, compared with the feeding method in the background art, in which the tubular workpiece to be detected is clamped by a clamping jaw, the clamping jaw rises and translates above the bearing groove of the support seat, then the clamping jaw descends and releases the tubular workpiece to be detected to realize feeding, and finally the clamping jaw resets and moves above the end of the feeding conveyor belt again, the way of moving the tubular workpiece to be detected to the first bearing block in the utility model is more convenient and time-saving. Among them, the feeding mechanism is any existing conveying mechanism for storing and transporting the workpieces stored by itself to the required position, such as a vibrating disk, a conveyor belt, etc.

[0014] Preferably, a plane along the length direction is provided on the upper side of the extending part, and protrusions are provided on both sides of the plane along the length direction.

[0015] Among them, the length of the platform is greater than the length of the workpiece to be detected. When the extending part extends into the tubular workpiece to be detected, the inner wall of the tubular workpiece to be detected slides between the protrusions on both sides of the platform of the extending part. The protrusions on both sides of the platform of the extending part are in contact with the inner wall of the tubular workpiece to be detected, and the axial and radial directions of the tubular workpiece to be detected are supported by the protrusions on both sides of the platform. Compared with the method of using a round rod with a circular cross-section in the prior art as the extending part, it can prevent the axial movement of the tubular workpiece to be detected even when the round rod is pressed by the tubular workpiece to be detected, so as to prevent the workpiece from falling. The peripheral air flow of the tubular workpiece to be detected is reduced by the two side edges of the platform of the extending part during the handling process, so as to reduce the entry of dust inside the tubular workpiece to be detected and improve the subsequent detection accuracy.

[0016] Preferably, a gap is provided between the first bearing block and the feeding groove.

[0017] The first bearing block and the second bearing block are respectively connected to the platform. By isolating the first bearing block and the second bearing block, there is no connecting structure between the adjacent sides of the first bearing block and the second bearing block. Since the mechanical setting method of the feeding mechanism will inevitably generate vibration, compared with the direct connection between the first bearing block and the feeding groove and between the first bearing block and the second bearing block, it can weaken the influence of the vibration of the feeding mechanism itself on the first bearing block and the second bearing block, thus ensuring the detection accuracy of subsequent visual inspection.

[0018] Preferably, the lower end surface of the feeding groove is located above the support groove of the first bearing block.

[0019] When the tubular workpiece to be inspected moves towards the first bearing block and the driving component is about to drive the tubular workpiece to be inspected to move in the axial direction, the anti-slip lines on the extending part can prevent the axial movement of the tubular workpiece to be inspected due to inertia.

[0020] Preferably, a shock-absorbing base is provided below the feeding mechanism.

[0021] During the process of the feeding mechanism transporting the tubular workpiece to be inspected to the feeding groove and the first bearing block, through the provided shock-absorbing base, the vibration generated by the feeding mechanism itself on the platform and the first bearing block and the second bearing block driven by the platform is prevented; among them, the material of the shock-absorbing base is made of any existing shock-absorbing material, such as EVA, ACF bionic cartilage supermaterial, D3O material, pu, etc.

[0022] Preferably, the driving component includes a first driver and a third driver for driving the extending part to translate along the horizontal plane. The driving component further includes a second driver for driving the extending part to lift. The second driver is arranged at the power output end of the first driver, the third driver is arranged at the power output end of the second driver, and the extending part is arranged at the power output end of the third driver.

[0023] The utility model has the advantages of being able to improve the detection efficiency without waiting for the feeding of the tubular workpiece to be inspected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The utility model is further described below based on the accompanying drawings and specific embodiments.

[0031] Depend on Figure 1 As shown, this embodiment discloses a loading device for detecting tubular workpieces, including a first bearing block 30 located at a loading station, two second bearing blocks 31 located at a detection station, and five groups of unloading blocks 43 located at a unloading station. The first bearing block 30, the second bearing block 31 and the unloading blocks 43 are all provided with a supporting groove 34 opening upward, and the supporting groove 34 is a V-shaped groove and is arranged to penetrate from front to back.

[0032] The two ends of the support groove 34 of the first bearing block 31 are respectively used to connect the discharge end of the feeding mechanism and the insertion part 24 to extend therein, the feeding mechanism has a feeding groove 13 which is used to extend in the same direction as the support groove 34 of the first bearing block 31 and is docked, the feeding mechanism also includes a vibration plate 11, a straight vibrator and a shock-absorbing base 12 arranged on the lower side of the vibration plate, a gap is provided between the first bearing block 30 and the feeding groove 13, the gap between the first bearing block 30 and the feeding groove 13 is smaller than the axial length of the tubular workpiece, the lower end surface of the feeding groove 13 is located on the upper side of the support groove 34 of the first bearing block 30, the first bearing block 30 and the second bearing block 31 are arranged side by side, the first bearing block 30 and the second bearing block 31 are equipped with a moving mechanism, and the extension direction of the insertion part 24 is parallel to the extension direction of the support groove 34.

[0033] Depend on Figure 2As shown, the moving mechanism includes eight insertion parts 24 arranged side by side and used to insert into the support groove 34 and a driving assembly for realizing the lifting and translation of the insertion part 24. The driving assembly includes a first driver 20 and a third driver 21 for driving the insertion part 24 to translate along the horizontal platform. The driving assembly also includes a second driver 22 for driving the insertion part to lift and lower. The second driver 22 is arranged at the power output end of the first driver 20, and the third driver 21 is arranged at the power output end of the third driver 21. The insertion part 24 is arranged at the power output end of the second driver 22 through a connecting beam 23. Wing plates extend from the upper and lower sides of the connecting beam 23. The wing plates of the connecting beam 23 are used to increase the surface area of itself connected to the power output end of the second driver 22, thereby ensuring the stability of the insertion part 24 during movement.

[0034] Depend on Figure 3 As shown, a first station of the second bearing block 31 is equipped with a top camera 32, which is used to assist in detecting the total height, outer diameter, middle step size and both side step height of the tubular workpiece to be inspected. A second station of the second bearing block 31 is axially equipped with a side camera 33, which is used to assist in detecting the size of the inner hole of the tubular workpiece to be inspected, and calculate the taper and other information of the workpiece in combination with the top camera 32 and the system. The existing visual inspection system is used to detect whether the various dimensions of the tubular workpiece meet the requirements.

[0035] Depend on Figure 4 As shown, a platform 25 extending along the length direction is provided on the upper side of the insertion portion 24, and protrusions extending upward are provided on both sides of the platform 25 along the length direction. Space for making way for the workpiece is provided on the left and right sides of the platform 25, and the length of the platform 25 is greater than the length of the tubular workpiece to be inspected. When the insertion portion 24 is inserted into the interior of the tubular workpiece to be inspected, the inner wall of the tubular workpiece to be inspected is located between the two side walls of the platform 25 of the insertion portion 24 in the length direction. As the insertion portion 24 moves, the tubular workpiece to be inspected is restricted to the axis at the platform 25; compared with the method of using a round rod with a circular cross-section as the insertion portion 24 in the prior art, the axial movement of the tubular workpiece to be inspected can be prevented when the round rod is pressed down by the tubular workpiece to be inspected, thereby preventing the workpiece from falling; and the circumferential shaking of the tubular workpiece to be inspected during the transportation process is reduced, thereby reducing the surrounding air flow of the tubular workpiece to be inspected, reducing the entry of dust into the tubular workpiece to be inspected, and improving the subsequent side camera 33 The accuracy of photographing the tubular workpiece to be inspected.

[0036] When it is necessary to move the tubular workpiece to be inspected to the inspection station, the tubular workpiece to be inspected first enters the support groove 34 of the first bearing block 31 along the feeding groove 13 under the action of the vibrating disk 11. Subsequently, the extending part 24 extends into the tubular workpiece to be inspected under the action of the third driver 21. After the extension, the extending part 24 rises under the action of the second driver 22 and jacks up the tubular workpiece to be inspected located in the support groove 34 of the first bearing block 31. Subsequently, the extending part 24 translates to above the first station of the second bearing block 31 (i.e., the support groove 34 of the second bearing block 31) under the action of the first driver 20 and then moves downward. After the tubular workpiece to be inspected is moved to the set position, the extending part 24 continues to move downward until it separates from the tubular workpiece to be inspected, and then exits the inside of the tubular workpiece to be inspected to complete the loading of a tubular workpiece to be inspected. At this time, the top-down camera 32 works. After the top-down camera 32 completes its work, the driving assembly repeats the above steps to move the tubular workpiece to be inspected to the second station of the second bearing block 31 (i.e., the support groove of the next second bearing block). At this time, the side camera 33 works, and the vision detection system completes the detection of a single tubular workpiece in combination with the data obtained by the top-down camera 32.

[0037] As shown by Figure 1 , Figure 3 , Figure 5 , on the discharging side of the discharging block 43, there is a discharging track 44 connected. Above the discharging block 43, there is also a discharging mechanism equipped. The discharging mechanism includes a pushing block 42, a lifter 41 for driving the pushing block to lift, and a translator 40 for driving the lifter 41 to move horizontally. The five groups of discharging blocks 43 are respectively used to carry qualified products, products with unqualified total length and step length, products with unqualified outer diameter and step size, products with unqualified taper, products that cannot be judged (i.e., workpiece inclination, deviation of the center of the third station) and need to be re-measured, etc. The translator 40 and the lifter 41 are the same as any existing transmission mechanism (such as a cylinder) for realizing a reciprocating stroke. When it is necessary to control the discharging of the tubular workpiece corresponding to the inspection result, first make the power output end of the translator 40 extend, and then make the power output end of the lifter extend. The translator 40 and the lifter 41 drive the pushing block 42 of the corresponding discharging block 43 to move to the axial side of the inspected tubular workpiece. When the pushing block 42 is located on the axial side of the tubular workpiece away from the discharging track 44, the power output end of the translator 40 shortens, and the inspected tubular workpiece is pushed out of the support groove 34 of the discharging block 43.

[0038] The difference between this embodiment and the first embodiment is that each group of support grooves 34 corresponds to two extending parts 24. When it is necessary to drive the tubular workpiece to be inspected to move, the extending parts 24 extend between the groove wall of the support groove 34 and the outer wall of the tubular workpiece to be inspected.
