Description

Technical Field

[0001] The invention relates to the technical field of pin processing, in particular to a strength detection tool for pin processing. Background Art

[0002] The pin is a kind of fastener. When working, it is mainly used at the hinge of two parts to form a hinged connection. The pin not only has the function of positioning and fastening, but also has the function of transmission and support. It is used in many fields such as mechanical processing and automobile manufacturing. When processing the pin, it is necessary to test its strength to ensure that the performance of the pin meets the standard, prevent potential failures, and ultimately improve the stability of the pin during operation. When testing the pin, it is necessary to use strength testing tooling; Since the pins need to be used in different positions, the sizes of the pins are also different during actual production. Therefore, when the inspection tooling is working, it takes a lot of time to make the clamping tooling clamp pins of different sizes, which leads to low working efficiency of the device as a whole. In order to overcome the above defects, prior art 1 (Chinese patent application with application number CN201910742308.6 and application date 2019-08-13) is a multi-size pin drilling tool. When it is working, the pin is stored in the cavity, the pin is limited and pressed, and the pin can be drilled through the horizontal through hole and the vertical through hole. This method reduces the error of the product and improves the quality of the product. The setting of the gear rack transmission mechanism makes the device suitable for pins of various radius sizes, expanding the scope of application; There is also prior art 2 (Chinese patent application with application number CN202320464194.5 and application date 2023-03-13) a pin shaft detection tooling, which can be rotated and moved by a rotating handle through a threaded main rod when in use, and can adjust the distance between the fixed cylinder covers, which can facilitate the fixing of pin shafts of different lengths, and then can fix pin shafts of different diameters through a threaded screw, and can make the pin shaft fit on the ball for rotation, and can rotate to detect the pin shaft, which is more convenient to use and can improve the detection effect; During the pin inspection process, when defective products are detected, they need to be collected and processed. However, the device in the above application does not have a structure for quickly collecting defective products during use, which will affect the work efficiency of the staff.

[0007] Preferably, the cleaning assembly further comprises a delivery tube fixedly connected to the surface of the airbag, a nozzle is fixedly connected to the end of the delivery tube, and a first one-way valve is fixedly connected to the surface of the delivery tube.

[0008] Preferably, a connecting pipe is fixedly connected to the other side of the airbag, and a second one-way valve is fixedly connected to the surface of the connecting pipe.

[0009] Preferably, the unloading assembly also includes a lower connecting block fixedly connected to the lower surface of the operating table, and a long pin is rotatably arranged inside the lower connecting block, and a working plate is fixedly connected to the surface of the long pin, and a unloading port is opened on the surface of the operating table.

[0010] Preferably, the working plates are symmetrically distributed on both sides of the material discharge port, a limiting rod is fixedly connected to the inner wall of the operating table, and a force-bearing plate is movably connected to the surface of the limiting rod.

[0011] Preferably, a slide plate is fixedly connected to the lower surface of the force-bearing plate, and the upper surface of the slide plate is initially in contact with the lower surface of the working plate, and a first spring that plays an elastic reset role is fixedly connected to the surface of the force-bearing plate, and the other side of the first spring is fixedly connected to the inner wall of the operating table.

[0012] Preferably, the collecting assembly further comprises a column fixedly connected to the upper surface of the limiting frame, and the column passes through the interior of the operating table, and the column is slidably connected to the operating table.

[0013] Preferably, the upper surface of the column is fixedly connected to an auxiliary plate, and the upper surface of the auxiliary plate is fixedly connected to a fixed block, the surface of the force-bearing plate is fixedly connected to a cross plate, and the lower surface of the cross plate is fixedly connected to a push block, and the limiting frame is a structure that is wide at the top and narrow at the bottom.

[0014] Preferably, the push blocks are evenly spaced on the lower surface of the horizontal plate, and the left and right sides of the push blocks and the left and right sides of the fixed block are inclined. The lower surface of the auxiliary plate is fixedly connected to a second spring that plays an elastic reset role, and the other side of the second spring is fixedly connected to the upper surface of the operating table.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the strength detection tooling for pin processing adopts a new structural design, and can quickly clamp workpieces of different sizes through the extrusion plate, and is also provided with a cleaning component, which can blow away the dust on the surface of the operating table through the nozzle, which is convenient for subsequent cleaning work of the staff, and is also provided with a feeding component and a collecting component, so that the defective products in the detection process can be quickly discharged and collected, which simplifies the operation of the staff and improves the work efficiency. The specific contents are as follows: (1) When using the strength testing tool for pin processing, the workpiece to be tested is placed on the working plate, and the motor is started. The motor drives the movable plate and the extrusion plate to work through the threaded rod and the connecting shaft. Finally, the extrusion plates on the left and right sides clamp and fix the workpiece. The extrusion plates can quickly clamp workpieces of different sizes, and the work efficiency is high. (2) The strength testing tooling for the pin shaft processing, during the working process of the movable plate, the movable plate will squeeze the airbag. When the airbag is squeezed, air is blown through the delivery pipe and the nozzle, thereby cleaning the dust on the surface of the operating table. When the movable plate moves back and no longer squeezes the airbag, the airbag expands again. At this time, the airbag inhales air through the connecting pipe, which is convenient for the blowing work when the airbag is squeezed again; Furthermore, when the first one-way valve and the second one-way valve are in operation, the air flows in the direction from the connecting pipe to the nozzle, and a reverse flow does not occur, thereby ensuring the stability of the operation of the airbag and the nozzle; (3) The strength testing tooling for the pin processing, under normal conditions, the slide plate is in a state of supporting the working plate, at which time the feed opening is in a closed state, so that various operations on the operating table can be carried out normally; Furthermore, when unqualified products are detected, the motor can be rotated, and the movable plate will move to the side of the operating table. When the movable plate contacts and pushes the force-bearing plate, the force-bearing plate drives the sliding plate to move to the side synchronously. At this time, the working plate rotates under the action of its own gravity, and then the unloading port is opened, and the defective products fall down; Furthermore, when the force plate moves, it will squeeze the first spring, and when the movable plate moves back, the force plate will also move back under the action of the first spring and the limit rod. At this time, the slide plate will contact and push the working plate again, so that the working plate will rotate back to its original position, that is, the discharge port is blocked again, which is convenient for the discharge port to automatically discharge defective products next time. (4) The strength detection tooling for the pin processing limits the position where the defective products fall when the limit frame is working, so that the defective products can be collected better and faster by the staff; Furthermore, during the movement of the force-bearing plate, the horizontal plate will be driven to move synchronously. When the horizontal plate moves, the push block will be driven to move synchronously, and then the push block will intermittently push the fixed block. When the fixed block is pushed, the auxiliary plate and the column descend. At this time, the second spring is squeezed, and when the push block does not push the fixed block, the auxiliary plate and the column rise under the action of the second spring. The above process is repeated. Under the action of thrust and elastic force, the column and the limiting frame make reciprocating linear motion in the vertical direction, and then the limiting frame is in a vibrating state, which can better discharge defective products and allow the defective products to be better collected.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: By setting the squeezing plate 7, the device can quickly clamp workpieces of different sizes. At the same time, by setting the cleaning component, the dust on the surface of the operating table 1 can be quickly blown away, which is convenient for subsequent cleaning work by the staff. Figure 1-Figure 3 As shown: It includes an operating table 1, a bracket is fixedly connected to the lower surface of the operating table 1, a support plate is fixedly connected to the upper surface of the operating table 1, a motor 2 is bolted to the surface of the support plate, and a threaded rod 3 is fixedly connected to the output end of the motor 2; The upper surface of the operating table 1 is fixedly connected with a vertical plate 4, and the vertical plates 4 are symmetrically distributed on both sides of the operating table 1, and a connecting shaft 5 is fixedly connected between adjacent vertical plates 4, and a movable plate 6 is movably connected to the surface of the connecting shaft 5, and a pressing plate 7 is fixedly connected to the surface of the movable plate 6. A cleaning component is arranged on the upper surface of the operating table 1, and the cleaning component includes an air bag 9 bonded to the upper surface of the operating table 1, and when the cleaning component is working, the dust on the upper surface of the operating table 1 is blown away; A material unloading assembly is provided on the lower surface of the operating table 1, and the material unloading assembly includes a working plate 8 rotatably provided on the lower surface of the operating table 1, and a collecting assembly is provided on the lower surface of the operating table 1, and the collecting assembly includes a limiting frame 22 movably provided on the lower surface of the operating table 1, the threaded rod 3 is threadedly connected to the movable plate 6, and the movable plate 6 is symmetrically distributed on both sides of the threaded rod 3, and the spiral rotation directions of the left and right sides of the threaded rod 3 are opposite.

[0020] The cleaning component also includes a delivery tube 10 fixedly connected to the surface of the airbag 9, and a nozzle 12 is fixedly connected to the end of the delivery tube 10, and a first one-way valve 11 is fixedly connected to the surface of the delivery tube 10, and a connecting tube 13 is fixedly connected to the other side of the airbag 9, and a second one-way valve 14 is fixedly connected to the surface of the connecting tube 13.

[0021] When in use, the staff holds the workpiece to be inspected and aligns the end of the workpiece with the extrusion plate 7. At this time, the motor 2 is started, and the motor 2 drives the movable plate 6 and the extrusion plate 7 to work through the threaded rod 3 and the connecting shaft 5. At this time, the extrusion plates 7 on the left and right sides move to the middle position of the operating table 1, and finally clamp the workpiece. The extrusion plate 7 can quickly clamp workpieces of different sizes with high work efficiency. At this time, the workpiece can be inspected by the strength detection device. During the working process of the movable plate 6, the movable plate 6 will squeeze the airbag 9. When the airbag 9 is squeezed, air is blown through the delivery pipe 10 and the nozzle 12, thereby cleaning the dust on the surface of the operating table 1. When the movable plate 6 moves back and no longer squeezes the airbag 9, the airbag 9 expands again. At this time, the airbag 9 inhales air through the connecting pipe 13, which is convenient for the blowing work when the airbag 9 is squeezed again. When the airbag 9 is working, the first one-way valve 11 and the second one-way valve 14 make the air flow direction from the connecting pipe 13 to the nozzle 12, and backflow will not occur, thereby ensuring the stability of the operation of the airbag 9 and the nozzle 12.

[0022] Embodiment 2: Different from Embodiment 1, by setting a material discharge assembly, when unqualified products are detected, unqualified products can be quickly discharged, such as Figure 4-Figure 6 As shown: The unloading assembly also includes a lower connecting block 15 fixedly connected to the lower surface of the operating table 1, and a long pin 16 is rotatably arranged inside the lower connecting block 15, and a working plate 8 is fixedly connected to the surface of the long pin 16, and a unloading port 21 is opened on the surface of the operating table 1, and the working plates 8 are symmetrically distributed on both sides of the unloading port 21, and a limiting rod 19 is fixedly connected to the inner wall of the operating table 1, and a force plate 18 is movably connected to the surface of the limiting rod 19.

[0023] The lower surface of the force-bearing plate 18 is fixedly connected to a slide plate 17, and the upper surface of the slide plate 17 is initially in contact with the lower surface of the working plate 8, and the surface of the force-bearing plate 18 is fixedly connected to a first spring 20 that plays an elastic reset role, and the other side of the first spring 20 is fixedly connected to the inner wall of the operating table 1.

[0024] Under normal conditions, the slide plate 17 is in a state of supporting the working plate 8. At this time, the working plate 8 is in a horizontal state, that is, the discharge port 21 is blocked by the working plate 8 and is in a closed state, so that various operations on the operating table 1 can be carried out normally. When unqualified products are detected, the motor 2 can be rotated, and the movable plate 6 will move to the side of the operating table 1. When the movable plate 6 contacts and pushes the force-bearing plate 18, the force-bearing plate 18 drives the slide plate 17 to move synchronously to the side of the operating table 1. At this time, the working plate 8 rotates inside the lower connecting block 15 under the action of its own gravity, and then the discharge port 21 is opened, and the defective products fall down; When the force plate 18 moves, it will squeeze the first spring 20. When the movable plate 6 moves back, the force plate 18 will also move back under the action of the first spring 20 and the limit rod 19. At this time, the slide plate 17 will move back and contact and push the working plate 8. At this time, the working plate 8 and the long pin 16 rotate, and finally the working plate 8 rotates to a horizontal state again, which is convenient for the working plate 8 and the discharge port 21 to automatically discharge defective products next time.

[0025] Embodiment 3: Different from Embodiment 2, the collection component can limit the location where the defective products fall, making it easier for the defective products to be collected by the staff. Figure 7-Figure 9 As shown: The collecting assembly also includes a column 23 fixedly connected to the upper surface of the limiting frame 22, and the column 23 passes through the interior of the operating table 1, and the column 23 is slidably connected to the operating table 1, the upper surface of the column 23 is fixedly connected to an auxiliary plate 27, and the upper surface of the auxiliary plate 27 is fixedly connected to a fixed block 26, the surface of the force-bearing plate 18 is fixedly connected to a cross plate 24, and the lower surface of the cross plate 24 is fixedly connected to a push block 25, and the limiting frame 22 is a structure that is wide at the top and narrow at the bottom.

[0026] The push blocks 25 are evenly spaced on the lower surface of the transverse plate 24, and the left and right sides of the push blocks 25 and the left and right sides of the fixed block 26 are inclined. The lower surface of the auxiliary plate 27 is fixedly connected to a second spring 28 that plays an elastic reset role, and the other side of the second spring 28 is fixedly connected to the upper surface of the operating table 1.

[0027] When the limiting frame 22 is working, the position where the defective products fall is limited, so that the defective products can be collected by the staff better and faster. During the movement of the force-bearing plate 18, the horizontal plate 24 will be driven to move synchronously. When the horizontal plate 24 moves, the push block 25 will be driven to move synchronously, and then the push block 25 will intermittently push the fixed block 26. When the fixed block 26 is pushed, the auxiliary plate 27 and the column 23 descend. At this time, the second spring 28 is squeezed, and when the push block 25 continues to move until it does not push the fixed block 26, the auxiliary plate 27 and the column 23 rise under the action of the second spring 28, and the above process is repeated. Under the action of thrust and elastic force, the column 23 and the limiting frame 22 make reciprocating linear motion in the vertical direction, and then the limiting frame 22 is in a vibrating state, which can better discharge the defective products and make the defective products better collected.

[0028] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
