Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detecting vertical groove and horizontal groove positions of powder metallurgy disc parts, and particularly relates to a detection device and method for detecting vertical groove and horizontal groove positions of powder metallurgy disc parts. BACKGROUND

[0002] The production process of the powder metallurgy disc part is as follows: first, mixing multiple types of metal powder uniformly by a mixing device, then adding the mixed metal powder into a cavity of a pressing machine, and then pressing the metal powder by the pressing machine to obtain a powder metallurgy disc part with a required shape and a certain hardness in the cavity.

[0003] The structure of a powder metallurgy disc part 1 produced by a workshop is shown in Figures 1-4 The powder metallurgy disc part 1 is rectangular, a through hole 2 is formed in the powder metallurgy disc part 1 along the axial direction thereof, a square sink 3 is formed on the left end face of the powder metallurgy disc part 1 and is in communication with the through hole 2, a vertical groove 4 is formed on the top surface of the powder metallurgy disc part 1, and a horizontal groove 5 is formed on the right end face of the powder metallurgy disc part 1 and is located below the through hole 2, both the horizontal groove 5 and the vertical groove 4 are rectangular.

[0004] Technically, the positions of the vertical groove 4 and the horizontal groove 5 of a batch of powder metallurgy disc parts 1 need to be detected, that is, whether the distance A between the right side wall of the vertical groove 4 and the right end face of the powder metallurgy disc part 1 and the distance B between the bottom wall of the horizontal groove 5 and the bottom surface of the powder metallurgy disc part 1 are within the design range.

[0005] The method for a worker to detect the positions of the vertical groove 4 and the horizontal groove 5 of the powder metallurgy disc part 1 is as follows:

[0006] S1, the worker takes out one powder metallurgy disc part 1 and places it on the tabletop of a detection table;

[0007] S2, the worker respectively abuts the two clamping heads of a vernier caliper against the right end face of the powder metallurgy disc part 1 and the right side wall of the vertical groove 4 to measure the distance A, as shown in Figure 5 , and then the worker respectively abuts the two clamping heads of the vernier caliper against the bottom surface of the powder metallurgy disc part 1 and the bottom wall of the horizontal groove 5 to measure the distance B, as shown in Figure 5 ;

[0008] If both the distance A and the distance B are within the design range, it indicates that the positions of the vertical groove 4 and the horizontal groove 5 of the detected powder metallurgy disc part 1 meet the requirements, and thus the powder metallurgy disc part 1 is determined to be a qualified product.

[0009] If the measured interval A or interval B is not within the design range, it indicates that the groove position of the vertical groove 4 or horizontal groove 5 of the detected powder metallurgy disc piece 1 does not meet the requirements, and then it is determined that the powder metallurgy disc piece 1 is unqualified, thereby completing the groove position detection of the vertical groove 4 and horizontal groove 5 of a powder metallurgy disc piece 1.

[0010] S3, the worker repeats the operations of steps S1-S2 multiple times, that is, the groove position detection of the vertical groove 4 and horizontal groove 5 of a batch of powder metallurgy disc pieces 1 is completed.

[0011] However, the method used in the workshop can detect the groove position of the vertical groove 4 and horizontal groove 5 of a batch of powder metallurgy disc pieces 1, but in actual application, workers often feedback the following technical problems:

[0012] I, in step S2, the worker needs to use the vernier caliper twice to measure the interval A and interval B of the powder metallurgy disc piece 1, and then complete the groove position detection of the vertical groove 4 and horizontal groove 5 of a powder metallurgy disc piece 1. The entire operation is completed manually by the worker and is divided into two processes, which not only increases the working strength of the worker, but also increases the detection time, thereby reducing the detection efficiency of the groove position of the vertical groove 4 and horizontal groove 5 of the powder metallurgy disc piece 1.

[0013] II, 200 powder metallurgy disc pieces 1 are required to be detected in the workshop every day, and the worker can only detect the groove position of the vertical groove 4 and horizontal groove 5 of the powder metallurgy disc piece 1 one by one, which consumes a long time to detect all 200 powder metallurgy disc pieces 1 in a day, which undoubtedly further reduces the detection efficiency of the groove position of the vertical groove 4 and horizontal groove 5 of the powder metallurgy disc piece 1.

[0014] Therefore, a detection device and method for greatly reducing the working strength of workers and greatly improving the groove position detection efficiency of the vertical groove and horizontal groove of the powder metallurgy disc piece are needed. SUMMARY

[0085] A method for slot position detection of vertical slots and horizontal slots of powder metallurgy disc pieces, comprising the following steps:

[0086] S1, positioning two powder metallurgy disc pieces 1 as shown, the specific operation steps are: Figures 1-4

[0087] S11, the worker takes out two powder metallurgy disc pieces 1 to be detected;

[0088] S12, the worker puts the square sink 3 of one powder metallurgy disc piece 1 from right to left on the positioning block 27 of the left positioning assembly 10, because the outer contour of the positioning block 27 matches the square sink 3 of the powder metallurgy disc piece 1, so that the square sink 3 of the powder metallurgy disc piece 1 is positioned as a reference, as shown in Figure 17

[0089] S13, the worker repeats the operation of step S12 once to position the second powder metallurgy disc piece 1 on the positioning block 27 of the right positioning assembly 10, as shown in Figure 18

[0090] S2, control the two piston rods of the double-acting cylinder 9 to retract inward, the two piston rods drive the connecting plate 26 connected thereto to move inward, the connecting plate 26 drives the positioning block 27 to move inward synchronously, and the positioning block 27 drives the powder metallurgy disc piece 1 to move inward;

[0091] When the two piston rods of the double-acting cylinder 9 are completely retracted, the left powder metallurgy disc piece 1 enters the detection station of the left detection mechanism, as shown in Figure 19 At this time, the vertical slot 4 of the left powder metallurgy disc piece 1 is opposite to the first profiling block 19 of the vertical detection assembly 11 up and down, and the horizontal slot 5 of the powder metallurgy disc piece 1 is opposite to the second profiling block 24 of the horizontal detection assembly 12 left and right;

[0092] At the same time, the right powder metallurgy disc piece 1 enters the detection station of the right detection mechanism, at this time, the vertical slot 4 of the right powder metallurgy disc piece 1 is opposite to the first profiling block 19 of the vertical detection assembly 11 up and down, and the horizontal slot 5 of the powder metallurgy disc piece 1 is opposite to the second profiling block 24 of the horizontal detection assembly 12 left and right;

[0093] S3, control the piston rod of the down-drawing cylinder 28 of the down-drawing driving assembly to retract downward, the piston rod drives the floating plate 29 to move downward, the floating plate 29 presses the two fixed plates 15 of the vertical detection assembly 11 downward, the fixed plate 15 compresses the vertical spring 16 downward, the fixed plate 15 also drives the first movable rod 14 to move downward, the first movable rod 14 drives the first pressure sensor 18 and the first profiling block 19 to move toward the vertical slot 4 of the powder metallurgy disc piece 1, the movement direction of the first profiling block 19 is as shown in Figure 20 ​​​The middle solid arrow indicates;

[0094] At the same time, the floating plate 29 also drives the support plate 30 to move downward, the support plate 30 drives the connecting rod 31 to move downward, the connecting rod 31 drives the rotating plate 33 to rotate downward around the hinge seat 34, the rotating plate 33 gradually pushes the roller 21 outward, the roller 21 drives the second movable rod 20 to move outward, the second movable rod 20 drives the second pressure sensor 23 and the second profiling block 24 to move toward the horizontal groove 5 of the powder metallurgy disc piece 1, and the movement direction of the second profiling block 24 is as shown in the figure. Figure 20 At the same time, the second pressure sensor 23 also gradually stretches the horizontal spring 25 outward;

[0095] When the piston rod of the pull-down cylinder 28 of the pull-down driving assembly is completely retracted, if the first pressure sensor 18 and the second pressure sensor 23 corresponding to the powder metallurgy disc piece 1 do not send pressure signals to the controller, it is indicated that the first profiling block 19 and the second profiling block 24 respectively enter the vertical groove 4 and the horizontal groove 5 of the powder metallurgy disc piece 1, as shown in the figure. Figure 21 Further, it is indicated that the groove positions of the vertical groove 4 and the horizontal groove 5 of the detected powder metallurgy disc piece 1 meet the requirements, and the worker determines that the detected powder metallurgy disc piece 1 is a qualified product;

[0096] If the first pressure sensor 18 corresponding to the powder metallurgy disc piece 1 sends a pressure signal to the controller, it is indicated that the first profiling block 19 does not enter the vertical groove 4 but presses on the top surface of the powder metallurgy disc piece 1, as shown in the figure. Figure 22 The first pressure sensor 18 sends a pressure signal to the controller after being subjected to the reaction force from the first profiling block 19, and further indicates that the groove position of the vertical groove 4 of the detected powder metallurgy disc piece 1 does not meet the requirements, and the worker determines that the detected powder metallurgy disc piece 1 is an unqualified product;

[0097] If the second pressure sensor 23 corresponding to the powder metallurgy disc piece 1 sends a pressure signal to the controller, it is indicated that the second profiling block 24 does not enter the horizontal groove 5 but presses on the end surface of the powder metallurgy disc piece 1, as shown in the figure. Figure 23 The second pressure sensor 23 sends a pressure signal to the controller after being subjected to the reaction force from the second profiling block 24, and further indicates that the groove position of the horizontal groove 5 of the detected powder metallurgy disc piece 1 does not meet the requirements, and the worker determines that the detected powder metallurgy disc piece 1 is an unqualified product, thereby finally completing the detection of the groove positions of the vertical groove 4 and the horizontal groove 5 of the two powder metallurgy disc pieces 1;

[0098] Wherein, from the steps S1~S3, it is known that the worker only needs to firstly position the powder metallurgy disc piece 1 on the positioning block 27, and then controls the two piston rods of the double-acting cylinder 9 to move inward, so that the powder metallurgy disc piece 1 enters the detection station of the vertical detection assembly 11 and the horizontal detection assembly 12; and finally controls the piston rod of the downward pulling cylinder 28 to retract downward, so that the slot positions of the vertical slot 4 and the horizontal slot 5 of the two powder metallurgy disc pieces 1 are detected.

[0099] Therefore, in the whole detection process, the worker does not need to use the vernier caliper twice to respectively measure the interval A and the interval B of the powder metallurgy disc piece 1, so as to complete the detection of the slot positions of the vertical slot 4 and the horizontal slot 5 of one powder metallurgy disc piece 1. However, the detection device only needs to cooperate the positioning block 27, the double-acting cylinder 9 and the downward pulling cylinder 28, so as to complete the automatic and rapid detection of the slot positions of the vertical slot 4 and the horizontal slot 5 of the powder metallurgy disc piece 1. This not only greatly reduces the working strength of the worker, but also shortens the detection time, and further greatly improves the detection efficiency of the slot positions of the vertical slot 4 and the horizontal slot 5 of the powder metallurgy disc piece 1.

[0102] S42, control the two piston rods of the double-acting cylinder 9 to stretch out outward, the two piston rods drive the connecting plate 26 connected therewith to move outward synchronously, the connecting plate 26 drives the positioning block 27 to move outward synchronously, and the positioning block 27 drives the qualified product or the unqualified product to move outward; when the positioning block 27 is reset, the worker takes away the qualified product or the unqualified product from the positioning block 27, and the taking away direction is shown by the solid arrow in the figure.

[0103] S5, the worker repeats the operation of the steps S1~S4 multiple times, so as to complete the slot position detection of the vertical slot 4 and the horizontal slot 5 of a batch of powder metallurgy disc pieces 1.

[0104] ​Further, it can be known from step S3 that the worker only needs to control the downward retraction of the piston rod of the downward pulling cylinder 28 of the downward pulling driving assembly, so that the first profiling blocks 19 of the two vertical detection assemblies 11 are respectively moved towards the vertical grooves 4 of the two powder metallurgy disc pieces 1, and the second profiling blocks 24 of the two horizontal detection assemblies 12 are respectively moved towards the horizontal grooves 5 of the two powder metallurgy disc pieces 1, thereby completing the detection of the vertical grooves 4 and the horizontal grooves 5 of the two powder metallurgy disc pieces 1 at one time. The number of the detected powder metallurgy disc pieces 1 is doubled compared with the original detection method, i.e. the worker does not need to detect the groove positions of the vertical grooves 4 and the horizontal grooves 5 of the powder metallurgy disc pieces 1 one by one, so that the 200 powder metallurgy disc pieces 1 in the workshop can be detected in a short time, thereby further improving the detection efficiency of the groove positions of the vertical grooves 4 and the horizontal grooves 5 of the powder metallurgy disc pieces 1.

Place the square sink (3) of a powder metallurgy disc (1) onto the positioning block (27) of the positioning component (10) on the left side from right to left. Since the outer contour of the positioning block (27) matches the square sink (3) of the powder metallurgy disc (1), positioning is achieved based on the square sink (3) of the powder metallurgy disc (1). S13. The worker repeats step S12 once to position the second powder metallurgy disc (1) on the positioning block (27) of the positioning assembly (10) on the right. S2. Control the two piston rods of the double-acting cylinder (9) to retract inward. The two piston rods drive the connecting plate (26) connected to them to move inward. The connecting plate (26) drives the positioning block (27) to move inward synchronously. The positioning block (27) drives the powder metallurgy disc (1) to move inward. When the two piston rods of the double-acting cylinder (9) are fully retracted, the powder metallurgy disc (1) on the left enters the detection station of the left detection mechanism. At this time, the vertical groove (4) of the powder metallurgy disc (1) on the left is vertically opposed to the first contour block (19) of the vertical detection component (11), and the horizontal groove (5) of the powder metallurgy disc (1) is horizontally opposed to the second contour block (24) of the horizontal detection component (12). At the same time, the powder metallurgy disc (1) on the right enters the detection station of the right detection mechanism. At this time, the vertical groove (4) of the powder metallurgy disc (1) on the right is vertically opposed to the first contour block (19) of the vertical detection component (11), and the horizontal groove (5) of the powder metallurgy disc (1) is horizontally opposed to the second contour block (24) of the horizontal detection component (12). S3. The piston rod of the pull-down cylinder (28) of the control pull-down drive assembly retracts downward, and the piston rod drives the floating plate (29) to move downward. The floating plate (29) presses down on the fixing plate (15) of the two vertical detection components (11). The fixing plate (15) compresses the vertical spring (16) downward. The fixing plate (15) also drives the first movable rod (14) to move downward. The first movable rod (14) drives the first pressure sensor (18) and the first contour block (19) to move toward the vertical groove (4) of the powder metallurgy disc (1). At the same time, the floating plate (29) also drives the support plate (30) to move downward, the support plate (30) drives the connecting rod (31) to move downward, the connecting rod (31) drives the rotating plate (33) to rotate downward around the hinge seat (34), the rotating plate (33) gradually pushes the roller (21) outward, the roller (21) drives the second movable rod (20) to move outward, the second movable rod (20) drives the second pressure sensor (23) and the second contour block (24) to move towards the horizontal groove (5) of the powder metallurgy disc (1), at the same time, the second pressure sensor (23) also gradually stretches the horizontal spring (25) outward; When the piston rod of the pull-down cylinder (28) of the pull-down drive assembly is fully retracted, if neither the first pressure sensor (18) nor the second pressure sensor (23) corresponding to the powder metallurgy disc (1) sends a pressure signal to the controller, it indicates that the first contour block (19) and the second contour block (24) have entered the vertical groove (4) and horizontal groove (5) of the powder metallurgy disc (1) respectively, which further indicates that the groove positions of the vertical groove (4) and horizontal groove (5) of the tested powder metallurgy disc (1) meet the requirements, and the worker judges the tested powder metallurgy disc (1) to be a qualified product; If the first pressure sensor (18) corresponding to the powder metallurgy disc (1) sends a pressure signal to the controller, it indicates that the first contour block (19) did not enter the vertical groove (4) but was pressed onto the top surface of the powder metallurgy disc (1). After the first pressure sensor (18) receives the reaction force from the first contour block (19), it sends a pressure signal to the controller, which indicates that the groove position of the vertical groove (4) of the tested powder metallurgy disc (1) does not meet the requirements. The worker judges the tested powder metallurgy disc (1) to be a defective product. If the second pressure sensor (23) corresponding to the powder metallurgy disc (1) sends a pressure signal to the controller, it indicates that the second contour block (24) did not enter the horizontal groove (5) but pressed onto the end face of the powder metallurgy disc (1). After the second pressure sensor (23) receives the reaction force from the second contour block (24), it sends a pressure signal to the controller, which indicates that the groove position of the horizontal groove (5) of the powder metallurgy disc (1) being tested does not meet the requirements. The worker judges the powder metallurgy disc (1) being tested to be a defective product, thus finally completing the testing of the vertical groove (4) and horizontal groove (5) positions of the two powder metallurgy discs (1). S4. The specific operating procedures for removing qualified or unqualified products are as follows: S41.

The floating plate (29) drives the support plate (30) to move upward, and the support plate (30) drives the rotating plate (33) to rotate upward around the hinge seat (34). When the floating plate (29) moves upward, under the elastic restoring force of the vertical spring (16), the first movable rod (14), the first pressure sensor (18) and the first contour block (19) are reset. At the same time, under the elastic restoring force of the horizontal spring (25), the second movable rod (20), the second pressure sensor (23) and the second contour block (24) are reset. S42. The two piston rods of the double-acting cylinder (9) extend outwards, and the two piston rods drive the connecting plate (26) connected to them to move outwards synchronously. The connecting plate (26) drives the positioning block (27) to move outwards synchronously. The positioning block (27) drives the qualified or unqualified product to move outwards.
