Description

Technical Field

[0001] This invention relates to the technical field of workpiece debugging and fixing, and specifically to a pin device based on a hydraulic detection system. Background Technology

[0002] Before testing, the workpiece needs to be fixed with pins. The difficulty of pinning large-mass workpieces lies in their large size and heavy weight, which requires the use of large machines for processing and installation. The pins also require high precision, necessitating fine processing technology and technical support.

[0003] Traditional pin fixing methods typically use guide pins to forcibly twist the workpiece and assist in inserting the fixing post into the pin hole. However, since some workpieces are quite heavy and the size of the fixing pin holes varies, the edges of the pin holes are easily damaged when the fixing post is inserted, which can also cause obstacles during the subsequent removal of the fixing post. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, the present invention aims to provide a pin insertion device based on a hydraulic detection system that uses a hydraulic detection system to accurately position the pin hole and assist in workpiece adjustment.

[0005] The technical solution adopted in this invention is: a pin device based on a hydraulic detection system, including a base plate, the base plate being used to support the equipment;

[0006] The fixing mechanism includes two sets of positioning bearing plates, which are symmetrically arranged. Each positioning bearing plate is provided with a plurality of first hydraulic columns. Each first hydraulic column is provided with a plurality of detector blocks arranged in a ring. The plurality of detector blocks are circumferentially wrapped around and slidably connected to the movable column of the first hydraulic column. The detector blocks are inserted into and slidably connected to the positioning bearing plate to abut against and adjust the workpiece. A pusher is provided on one side of each of the detector blocks.

[0007] The material-bearing adjustment mechanism consists of several sets of the material-bearing adjustment mechanisms arranged in a straight line on one side of the two sets of positioning bearing plates. The material-bearing adjustment mechanism carries the workpiece and assists the workpiece in moving from the bearing surface.

The sliding protrusion on the probe block passes into the sliding limiting grooves so that the probe block slides along the moving direction of the first hydraulic column.

[0009] In one embodiment, the hydraulic end of the first hydraulic column is provided with a support frame, which is fixedly connected to the base plate.

[0010] In one embodiment, the pusher includes a torsion ring rotatably connected to the middle of the movable column of the first hydraulic column.

The movable inclined groove and the buffer ring groove are interconnected, and the toggle rod passes into the movable inclined groove.

[0011] In one embodiment, let X be the angle between the two ends of the outer arc surface of the probe block and the center of the circle, and let Y be the angle of the buffer ring groove along the outer arc surface of the probe block, where X > 2Y ≥ 0.

[0012] In one embodiment, the fixing pin mechanism further includes a movable component, the movable component including a drive gear ring, the drive gear ring being sleeved with the torsion ring, a control rack being provided on one side of the drive gear ring, the control rack engaging the drive gear ring, and a second hydraulic column being provided on the control rack, the second hydraulic column being fixedly connected to the base plate.

[0013] In one embodiment, the material-bearing adjustment mechanism includes a third hydraulic column, which is fixedly connected to the base plate. A lifting block is provided on the movable column of the third hydraulic column. The lifting block has a U-shaped structure, and a sliding round rod passes through the middle of the lifting block. A material-bearing platform is provided on the side of the lifting block away from the third hydraulic column. Two sets of adjusting arc blocks are provided below the material-bearing platform. The adjusting arc blocks have an arc-shaped ring structure, and the ends of the rings are fixedly connected to the material-bearing platform. An arc-shaped groove is provided on the adjusting arc blocks. The two ends of the sliding round rod pass through the arc-shaped groove and are slidably connected to the adjusting arc blocks.

[0014] In one embodiment, the material-bearing platform is provided with a plurality of anti-slip fixing teeth on the side away from the third hydraulic column. The plurality of anti-slip fixing teeth are symmetrically arranged to reduce the contact area with the workpiece, increase the fixing pressure, and assist the material-bearing platform in swinging.

[0015] In one embodiment, the material-bearing adjustment mechanism further includes two sets of balance bars, one end of which is hinged to each other. The hinge is penetrated by the sliding round rod and is disposed in the inner cavity of the U-shaped part of the lifting block. A movable groove is provided on the side of the balance bar away from the sliding round rod. A balance support block is provided in the movable groove. The middle crossbar of the balance support block passes through the movable groove and is slidably connected to the balance bar. A clamping rod is provided on the end of the balance bar away from the movable groove. An auxiliary rod is hinged to the end of the clamping rod away from the balance bar.

[0016] In one embodiment, a fourth hydraulic column is provided in the middle of the auxiliary rod, the movable column of the fourth hydraulic column is hinged to the auxiliary rod, the hydraulic end of the fourth hydraulic column is hinged to the base plate, the end of the auxiliary rod abuts against the workpiece, and the fourth hydraulic column assists the auxiliary rod in positioning and cooperates with the material-bearing platform to tilt the workpiece.

[0017] The beneficial effects of this invention are as follows: This invention is a pin-insertion device based on a hydraulic detection system, which uses a hydraulic detection system to accurately position the pin hole and assist in workpiece adjustment. Its specific implementation is shown below:

[0018] After the operator places the workpiece above the support platform, the third hydraulic column is lowered, which drives the balance bars on both sides to expand outward and widen their included angle. Then the balance bars continue to drive the clamping rods to close together, bringing the ends of the auxiliary rods to the sides of the workpiece. The fourth hydraulic column can help the auxiliary rods to better fit the workpiece and prevent the workpiece from tilting.

[0019] Afterwards, once the workpiece's pin hole is placed between the positioning bearing plates, the workpiece's position is gradually adjusted until the projection of its pin hole axis, the projection of the first hydraulic column it is inserted into, and the projection of the center axis of the probe block are aligned. At this point, the pin hole and the movable column of the first hydraulic column to be inserted are adjusted.

[0020] The second hydraulic column is activated, pushing the control rack to rotate and drive the gear ring. The gear ring drives the torsion ring to rotate, and at the same time, it drives the actuating rod to slide between the movable inclined groove and the buffer ring groove on multiple sets of probe blocks. When it slides from the buffer ring groove to the movable inclined groove, since the position of the actuating rod is fixed, the actuating rod slides in the connection direction of the sliding protrusion of the probe block, so that it abuts the workpiece in advance and generates resistance feedback to the second hydraulic column. If the second hydraulic column does not receive assistance feedback, it continues to drive the torsion ring to rotate. If the torsion ring still does not receive resistance feedback from the workpiece against the probe block after rotating one revolution, the first hydraulic column can be activated again to push the first hydraulic column and the probe block into the pin hole at the same time to complete the pin fixing work.

[0021] However, in most cases, when the actuating lever rotates to the movable groove of a certain probe block, the probe block contacts the workpiece in advance, and the actuating lever is assisted and transmitted to the second hydraulic column. At this time, the second hydraulic column returns to its initial state, so that all probe blocks are located back in the middle of the movable rod of the first hydraulic column. Then, the material-bearing adjustment mechanism is activated to adjust in the opposite direction to the position where the probe block is in contact. After the adjustment is completed, the above process is repeated until the torsion ring rotates one revolution and there is still no resistance feedback from the workpiece against the probe block. Then, the first hydraulic column and the probe block are pushed into the pin hole at the same time to complete the pin fixing work.

[0022] During workpiece adjustment, the height of the workpiece in contact with the anti-slip fixed teeth can be adjusted by activating the third hydraulic column. If the workpiece needs to be adjusted to the left or right, the fourth hydraulic column is activated, which changes the height of the fourth hydraulic column at both ends of the workpiece. This causes the workpiece to shift on both sides of the support where the auxiliary rod contacts the workpiece, resulting in a change in the center and causing the workpiece to tilt. This causes the adjusting arc block under the material receiving platform to slide on the sliding rod. Once the workpiece reaches the qualified position, the fourth hydraulic columns on both sides are fixed, thus completing the adjustment of the left and right height of the workpiece.

[0023] This equipment is easy to operate. After detecting the position of the sensing pin hole through simple hydraulic contact, the workpiece is twisted and lifted. It effectively solves the problem of positional misalignment between the pin hole and the fixing post when the pin is fixed. It has good practicality and economic benefits, which is conducive to the promotion and use of the equipment. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] The following is combined with Figure 1-8 This invention describes a specific embodiment of a pin device based on a hydraulic detection system, comprising:

[0037] Reference Figure 1 , 2 As shown, base plate 1 is used to support the equipment;

[0038] Fixing mechanism 2 includes two sets of positioning bearing plates 23, which are symmetrically arranged. The test workpiece is placed within the interval between them, for reference. Figure 3 As shown, the positioning bearing plate 23 is equipped with three sets of first hydraulic columns 21;

[0039] Specifically, the first hydraulic column 21 and other hydraulic columns with subsequent names mainly consist of a hydraulic end that provides thrust and a retractable movable end. This type of hydraulic column is controlled by default and can collect information such as mass, thrust, and tension, as well as perform linkage and other functions. At the same time, this type of hydraulic column is existing equipment and is not part of the inventive point of this invention, so it will not be described in detail here.

[0040] Reference Figure 4 , 5 As shown, the first hydraulic column 21 is provided with multiple sets of detector blocks 25 arranged in a ring. Several detector blocks 25 are circumferentially wrapped around and slidably connected to the movable column of the first hydraulic column 21. The various detector blocks 25 are arranged in a ring and can move independently. The outer periphery of the detector blocks 25 is inserted into and slidably connected to the positioning support plate 23 to abut against the workpiece for adjustment. The detector blocks 25 have an arc-shaped long plate structure. The outer ring arc of the detector blocks 25 is concentric with the movable column of the first hydraulic column 21. The detector blocks 25 are provided with sliding protrusions 253 inside. The movable column of the first hydraulic column 21 is provided with several sliding limit grooves 211. The sliding protrusions 253 on the detector blocks 25 are inserted into the sliding plate. The limiting groove 211 allows the probe block 25 to slide along the direction of movement of the first hydraulic column 21. A pusher is provided on one side of several probe blocks 25; the pusher includes a torsion ring 24, which is rotatably connected to the middle of the movable column of the first hydraulic column 21. An extension rod 241 is provided on the torsion ring 24, and a toggle rod 242 is provided on the extension rod 241. A movable inclined groove 251 and a buffer ring groove 252 are provided on the outer arc surface of the probe block 25. The movable inclined groove 251 and the buffer ring groove 252 are interconnected, with both ends of the two grooves penetrating both sides of the outer arc surface of the probe block 25. The toggle rod 242 slides into the movable inclined groove 251.

[0041] Reference Figure 6 As shown, in implementation, the second hydraulic column 4 is activated, pushing the control rack 41 to rotate and drive the gear ring 411. The gear ring 411 drives the torsion ring 24 to rotate, and simultaneously drives the actuating rod 242 to slide between the movable inclined groove 251 and the buffer ring groove 252 on the multiple sets of probe blocks 25. When it slides from the buffer ring groove 252 to the movable inclined groove 251, since the position of the actuating rod 242 is fixed, the actuating rod 242 slides in the connection direction of the sliding protrusion 253 of the probe block 25, so that it abuts the workpiece in advance and generates resistance feedback to the second hydraulic column 4. If the second hydraulic column 4 does not receive resistance feedback, it continues to drive the torsion ring 24 to rotate. If the torsion ring 24 still does not receive resistance feedback from the workpiece against the probe block 25 after rotating one revolution, the first hydraulic column 21 can be activated to push the first hydraulic column 21 and the probe block 25 into the pin hole at the same time to complete the pin fixing work.

[0042] Beneficially, the hydraulic end of the first hydraulic column 21 is provided with a support frame 3, which is fixedly connected to the base plate 1.

[0043] Beneficially, let X be the angle between the two ends of the outer arc surface of the detector block 25 and the center of the circle, and let Y be the angle of the buffer ring groove 252 along the outer arc surface of the detector block 25, where X>2Y≥0.

[0044] Specifically, since the hydraulic column needs to adjust the contact data during the process of the probe block 25 abutting against the workpiece pin hole, the data processing time can be increased during the sliding of the toggle rod 242 in the buffer ring groove 252 to avoid damaging the workpiece.

[0045] Beneficially, the fixed pin mechanism 2 also includes a movable component, which includes a drive gear ring 411. The drive gear ring 411 is sleeved with a torque ring 24. A control rack 41 is provided on one side of the drive gear ring 411. The control rack 41 meshes with the drive gear ring 411. A second hydraulic column 4 is provided on the control rack 41. The second hydraulic column 4 is fixedly connected to the base plate 1.

[0046] Reference Figure 7 , 8 As shown, the material-bearing adjustment mechanism 5 consists of several sets of material-bearing adjustment mechanisms 5 arranged in a straight line on one side of two sets of positioning bearing plates 23. The material-bearing adjustment mechanism 5 carries the workpiece and assists the workpiece in moving from the bearing surface. The material-bearing adjustment mechanism 5 includes a third hydraulic column 53, which is fixedly connected to the base plate 1. A lifting block 52 is provided on the movable column of the third hydraulic column 53. The lifting block 52 has a U-shaped structure, and a sliding round rod 521 passes through the middle of the lifting block 52. A material-bearing platform 51 is provided on the side of the lifting block 52 away from the third hydraulic column 53. Two sets of adjusting arc blocks 512 are provided below the material-bearing platform 51. The adjusting arc blocks 512 have an arc-shaped ring structure, and the ends of the rings are fixedly connected to the material-bearing platform 51. The adjusting arc blocks 512 have an arc-shaped through-hole arc groove 51201. The two ends of the sliding round rod 521 pass through the arc groove 51201 and are slidably connected to the adjusting arc. Block 512; The material-bearing adjustment mechanism 5 also includes two sets of balance bars 55. One end of the two sets of balance bars 55 is hinged to each other. The hinge is penetrated by a sliding round rod 521 and is located in the U-shaped cavity of the lifting block 52. A movable slide groove 551 is provided on the side of the balance bar 55 away from the sliding round rod 521. A balance support block 54 is provided in the movable slide groove 551. The middle crossbar of the balance support block 54 passes through the movable slide groove 551 and is slidably connected to the balance bar 55. A clamping rod 56 is provided at the end of the balance bar 55 away from the movable slide groove 551. An auxiliary rod 57 is hinged to the end of the clamping rod 56 away from the balance bar 55. A fourth hydraulic column 58 is provided in the middle of the auxiliary rod 57. The movable column of the fourth hydraulic column 58 is hinged to the auxiliary rod 57. The hydraulic end of the fourth hydraulic column 58 is hinged to the base plate 1. The end of the auxiliary rod 57 abuts against the workpiece. The fourth hydraulic column 58 assists the auxiliary rod 57 in positioning and cooperates with the material-bearing platform 51 to tilt the workpiece.

[0047] In practice, when the workpiece needs to be adjusted in the left and right height, the fourth hydraulic column 58 is activated, which changes the height of the fourth hydraulic column 58 at both ends of the workpiece. The offset of the support sides of the workpiece in contact with the auxiliary rod 57 causes the center to change, causing the workpiece to tilt. This causes the adjusting arc block 512 under the material receiving platform 51 to slide on the sliding rod 521. After reaching the qualified position, the fourth hydraulic column 58 on both sides is fixed, thus completing the adjustment of the left and right height of the workpiece.

[0048] Beneficially, the material-bearing platform 51 is provided with several anti-slip fixing teeth 511 on the side away from the third hydraulic column 53. The several anti-slip fixing teeth 511 are symmetrically arranged to reduce the contact area with the workpiece, increase the fixing pressure, and assist the material-bearing platform 51 in swinging.

[0049] Working principle of this invention:

[0050] After the operator places the workpiece on the material support platform 51, the third hydraulic column 53 is lowered, which drives the balance bars 55 on both sides to expand outward and widen their included angle. Then the balance bars 55 continue to drive the clamping rods 56 to close together, so that the end of the auxiliary rod 57 abuts against both sides of the workpiece. The fourth hydraulic column 58 can help the auxiliary rod 57 to better fit the workpiece and prevent the workpiece from tilting.

[0051] Afterwards, once the pin hole of the workpiece is placed between the positioning bearing plates 23, the position of the workpiece is gradually adjusted so that the projection of the pin hole axis is aligned with the projection of the central axis of the first hydraulic column 21 into which it is inserted and the probe block 25. At this point, the pin hole is adjusted to match the movable column of the first hydraulic column 21 into which it is inserted.

[0052] The second hydraulic column 4 is activated, pushing the control rack 41 to rotate and drive the gear ring 411. The gear ring 411 drives the torsion ring 24 to rotate and simultaneously drives the actuating rod 242 to slide between the movable inclined groove 251 and the buffer ring groove 252 on the multiple sets of probe blocks 25. When it slides from the buffer ring groove 252 to the movable inclined groove 251, since the position of the actuating rod 242 is fixed, the actuating rod 242 slides in the connection direction of the sliding protrusion 253 of the probe block 25, so that it abuts the workpiece in advance and generates resistance feedback to the second hydraulic column 4. If the second hydraulic column 4 does not receive assistance feedback, it continues to drive the torsion ring 24 to rotate. If the torsion ring 24 still does not receive resistance feedback from the workpiece against the probe block 25 after rotating one revolution, the first hydraulic column 21 can be activated to push the first hydraulic column 21 and the probe block 25 into the pin hole at the same time to complete the pin fixing work.

[0053] However, in most cases, when the actuating lever 242 rotates to the movable inclined groove 251 of a certain probe block 25, the probe block 25 contacts the workpiece in advance, and the actuating lever 242 generates assistance which is transmitted to the second hydraulic column 4. At this time, the second hydraulic column 4 returns to its initial state, so that all probe blocks 25 return to the middle of the movable rod of the first hydraulic column 21. Then, the material carrying adjustment mechanism 5 is activated to adjust in the opposite direction to the position where the probe block 25 is in contact. After the adjustment is completed, the above process is repeated until the torsion ring 24 rotates one revolution and there is still no resistance feedback from the workpiece against the probe block 25. Then, the first hydraulic column 21 and the probe block 25 are pushed into the pin hole at the same time to complete the pin fixing work.

[0054] During the workpiece adjustment process, the third hydraulic column 53 can be activated to adjust the height of the workpiece in contact with the anti-slip fixing tooth 511. If the workpiece needs to be adjusted to the left or right, the fourth hydraulic column 58 is activated to change the height of the fourth hydraulic column 58 at both ends of the workpiece. The support sides of the workpiece in contact with the auxiliary rod 57 shift, causing the center to change and the workpiece to tilt. This causes the adjusting arc block 512 under the material receiving platform 51 to slide on the sliding rod 521. After reaching the qualified position, the fourth hydraulic columns 58 on both sides are fixed to complete the adjustment of the left and right height of the workpiece.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] The above description is merely an example and illustration of the structure of the present invention.
