Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a comprehensive inspection tool for pipe beam hole positions. Background Technology

[0002] Inspection tools are simple tools used by industrial manufacturing companies to control various dimensions of products (such as hole diameter, spatial dimensions, etc.), improve production efficiency and control quality, and are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools.

[0003] Tube beams are important components of automobiles. After production, the holes at both ends of the tube beams need to be inspected. Existing tube beam inspection fixtures use side inserts and inspection holes on the side inserts to inspect the holes at both ends of the tube beams. However, the holes on the side inserts are fixed and can only be used to inspect a single type of tube beam. This does not allow for the use of the same fixture to inspect tube beams of various specifications. When changing the specifications of the tube beam, the corresponding side inserts need to be replaced, which is a cumbersome process and increases the cost of the inspection fixture equipment. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a comprehensive inspection tool for pipe beam hole positions, which can adjust the position of the inspection hole so that one tool can meet the inspection of the hole positions of the machined holes at both ends of pipe beams of various specifications, thereby reducing the cost of inspection tools.

[0005] This utility model provides a comprehensive inspection tool for pipe beam hole positions, comprising:

[0006] Two sets of symmetrically arranged hole position detection mechanisms include a longitudinal adjustment component, a horizontal plate and a vertical plate. The horizontal plate has a first through hole along its length direction, and the vertical plate has multiple detection holes for the detection pin to pass through. The detection pin can pass through the detection holes and the first through hole at the same time, and is used to detect the hole positions of the machined holes at both ends of the tube beam.

[0007] The vertical plate can be translated along the length of the horizontal plate, and the longitudinal adjustment mechanism is connected to the horizontal plate and can drive the horizontal plate to move in the vertical direction;

[0008] The clamping mechanism, located between the two sets of hole position detection mechanisms, is used to clamp and fix the tube beam body.

[0009] Furthermore, it also includes a mounting frame, in which the hole position detection mechanism is disposed, and a base plate is provided at the bottom of the mounting frame, with a reinforcing plate connecting the base plate and the mounting frame.

[0010] Furthermore, the longitudinal adjustment assembly includes a first screw, a synchronous pulley, a synchronous belt, and a drive motor. Two sets of the first screw are arranged in the vertical direction, and one end of each set of the first screw is rotatably connected to the mounting frame, while the other end of each set of the first screw is fixedly provided with the synchronous pulley. The synchronous belt is sleeved on the outer surface of the two sets of synchronous pulleys. The output end of the drive motor is fixedly connected to one set of synchronous pulleys for driving the first screw to rotate.

[0011] The horizontal plate is located between the two sets of the first screws, and both ends of the horizontal plate are threadedly connected to the first screws respectively.

[0012] Furthermore, the horizontal plate is provided with a second through hole along its length, and the second through hole is symmetrically arranged about the axis of the first through hole; the vertical plate is provided with multiple sets of fixing holes, and the vertical plate and the horizontal plate are fixedly connected by bolts and nuts.

[0013] Furthermore, the multiple detection holes on the vertical plate have different diameters, and the width of the first through hole is greater than the maximum diameter of the detection hole.

[0014] Furthermore, a wear-resistant sleeve is fixedly fitted inside the detection hole.

[0015] Furthermore, the clamping mechanism is provided in at least two sets, each including a fixed platform, a support plate, a second screw, a guide rod, a movable plate, and a clamping member. The support plates are symmetrically arranged on the fixed platform, and the movable plate is arranged between the two sets of support plates. One end of the second screw is threaded through the support plate and rotatably connected to the movable plate. The guide rod slides through the support plate and is fixedly connected to the movable plate. The clamping member is provided at the end of the movable plate away from the support plate. Rotating the second screw can cause the clamping members to move closer or further apart.

[0016] Furthermore, the clamping component includes multiple clamping plates and multiple telescopic cylinders. The multiple clamping plates are arranged sequentially along the length direction of the moving plate, and adjacent clamping plates are hinged together. Each telescopic cylinder corresponds to a clamping plate, and the piston rod of the telescopic cylinder is hinged to the corresponding clamping plate. The telescopic cylinder can extend and retract to drive the clamping plate to rotate around the hinge connection, so as to adjust the angle between adjacent clamping plates and make the multiple clamping plates distributed with different arcs.

[0017] Furthermore, the top surface of the fixed platform is provided with multiple reference holes for installing positioning pins.

[0018] Furthermore, it also includes a base, with the mounting frame symmetrically arranged on the top surface of the base, and the clamping mechanism also arranged on the top surface of the base.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model is provided with two sets of symmetrically arranged hole position detection mechanisms, which are symmetrically arranged at both ends of the tube beam. A clamping mechanism is arranged between the two sets of hole position detection mechanisms. The tube beam is fixed by the clamping mechanism, and the tube beam is positioned at the same time as it is fixed. Then, the hole position detection mechanism is used to detect the hole positions of the machined holes at both ends of the tube beam.

[0021] The hole position detection mechanism of this application includes a vertical plate with multiple detection holes and a horizontal plate with a first through hole along its length. The vertical plate can move along the length of the horizontal plate to adjust the horizontal position of the detection holes. The longitudinal adjustment component of the hole position detection mechanism can drive the horizontal plate to move vertically to adjust the vertical position of the detection holes. The horizontal and vertical positions of the detection holes can be adjusted according to the detection requirements of pipe beams of different specifications, so that the machined hole positions at the ends of pipe beams of different specifications can be detected, avoiding the need to change a different inspection tool for each type of pipe beam and reducing the cost of inspection tool equipment.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0036] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Please refer to Figures 1-3 This utility model provides a comprehensive inspection tool for pipe beam hole positions, used to inspect the hole positions of the machined holes at both ends of a pipe beam. The sliding plate type comprehensive inspection tool of this application includes a hole position detection mechanism 1 and a clamping mechanism 2. Two sets of hole position detection mechanisms 1 are symmetrically arranged, and the clamping mechanism 2 is disposed between the two sets of hole position detection mechanisms 1, used to clamp and fix the shaft of the pipe beam, and simultaneously position the pipe beam. The two sets of hole position detection mechanisms 1 are disposed at both ends of the pipe beam, used to inspect the hole positions of the machined holes at both ends of the pipe beam.

[0038] Preferably, the hole position detection mechanism 1 includes a longitudinal adjustment component 11, a horizontal plate 12, and a vertical plate 13. The horizontal plate 12 is provided with a first through hole 121 along its length direction, and the vertical plate 13 is provided with a plurality of detection holes 131 for the detection pin to pass through. The detection pin can pass through the detection holes 131 and the first through hole 121 at the same time to detect the hole position of the machined holes at both ends of the tube beam. The vertical plate 13 can be translated along the length direction of the horizontal plate 12. The longitudinal adjustment mechanism 11 is connected to the horizontal plate 12 and can drive the horizontal plate 12 to move in the vertical direction.

[0039] Specifically, multiple sets of horizontal plates 12 can be arranged in parallel, and multiple sets of vertical plates 13 are also provided on the horizontal plates 12. Multiple sets of horizontal plates 12 and multiple sets of vertical plates 13 can be fixed to form multiple inspection holes for inspecting multiple holes at the end of the pipe beam. The first through hole 121 provided along the length of the horizontal plate 12 is an oblong hole, and multiple inspection holes 131 for inspection pins to pass through are provided on the vertical plates 13. The width of the oblong hole is slightly larger than the diameter of the inspection hole 131. The inspection pin can pass through the inspection hole 131 and the oblong hole to inspect the holes at the end of the pipe beam. The oblong hole design allows for more flexible adjustment of the position of the vertical plate 13 on the horizontal plate 12. When it is necessary to inspect pipe beams of different specifications, the position of the inspection hole 131 can be adjusted according to the inspection requirements to meet the inspection of pipe beams of different specifications, avoiding multiple changes of inspection tools and reducing the investment in inspection tool equipment costs.

[0040] Before inspecting the hole positions at the end of a pipe beam of a certain specification, a ruler can be used to adjust the position of the inspection hole according to the inspection requirements. Before inspection, the pipe beam is first positioned and fixed by the clamping mechanism 2, and then the horizontal plate 12 is adjusted in the vertical direction by the longitudinal adjustment mechanism 11. Then, the position of the vertical plate 13 on the horizontal plate 12 is manually adjusted so that the specified inspection hole 131 and the first through hole 121 coincide, so that the inspection pin can pass through the inspection hole 131 and the first through hole and extend. The position of the inspection hole 131 is adjusted to the standard position suitable for inspecting the hole positions of the pipe beam. Then, the inspection pin is passed through the inspection hole 131 and the first through hole 121 and pushed in the direction close to the machined hole at the end of the pipe beam. If the inspection pin can slide into the machined hole, it proves that the hole position of the machined hole at the end of the pipe beam is correct. If the inspection pin cannot be inserted into the machined hole at the end of the pipe beam, it proves that the hole position of the machined hole at the end of the pipe beam is unqualified. Inspecting the hole positions at the end of the pipe beam by using the inspection pin is more convenient and faster.

[0041] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, it also includes a mounting frame 3, a hole position detection mechanism 1 is set inside the mounting frame 3, a base plate 4 is set at the bottom of the mounting frame 3, and a reinforcing plate 5 is connected between the base plate 4 and the mounting frame 3.

[0042] In this embodiment, the mounting frame 3 is a cuboid formed by connecting four plate-like structures end to end. There are two reinforcing plates 4, which are triangular structures, used to connect the side walls and the bottom plate 4 of the mounting frame 3, thereby increasing the stability of the mounting frame 3.

[0043] In a preferred embodiment, such as Figure 2As shown, the longitudinal adjustment assembly 11 includes a first screw 111, a synchronous pulley 112, a synchronous belt 113, and a drive motor 114. Two sets of first screws 111 are arranged in the vertical direction, and one end of each set of first screws 111 is rotatably connected to the mounting frame 3, while the other end is fixedly provided with a synchronous pulley 112. The synchronous belt 113 is sleeved on the outer surface of the two sets of synchronous pulleys 112. The output end of the drive motor 114 is connected to one of the sets of synchronous pulleys 112 to drive the first screw 111 to rotate.

[0044] The horizontal plate 12 is located between the two sets of first screws 111, and both ends of the horizontal plate 12 are threadedly connected to the first screws 111 respectively.

[0045] In this embodiment, the first screw 111 is fixedly connected to the center of the corresponding synchronous pulley 112, and the two sets of synchronous pulleys 112 are located in the same horizontal plane;

[0046] Starting the drive motor 114 will drive the two sets of synchronous pulleys 112 to rotate in the same direction, which in turn will drive the two sets of first screws 111 to rotate in the same direction. Since the two ends of the horizontal plate 12 are respectively threaded onto the two sets of first screws 111, the horizontal plate 12 can be raised and lowered along the length of the first screws 111, thereby adjusting the position of the horizontal plate 12 in the vertical direction. By setting the synchronous belt 113 to drive the two sets of first screws 111 to rotate in the same direction, the stability of the horizontal plate 12 during the up and down movement can be improved.

[0047] In a preferred embodiment, such as Figure 2 As shown, a second through hole 122 is provided on the horizontal plate 12 along its length direction, and the second through hole 122 is symmetrically arranged about the axis of the first through hole 121; multiple sets of fixing holes are provided on the vertical plate 13, and the vertical plate 13 and the horizontal plate 12 are fixedly connected by bolts and nuts.

[0048] In this embodiment, the second through hole 122 is also an oblong hole. The elongated structure of the oblong hole facilitates flexible adjustment of the fixed position of the vertical plate 13 on the horizontal plate 12. The distance between two adjacent sets of fixing holes on the vertical plate 13 along the vertical direction is equal to the distance between the second through holes 122 along the vertical direction. After the detection hole 131 on the vertical plate 13 is adjusted to the specified position, the bolt is passed through the fixing hole and the second through hole 122, and then the vertical plate 13 is fixed to the horizontal plate 12 with the nut. The vertical plate 13 and the horizontal plate 12 are fixed by bolts and nuts, which is simple and easy to implement.

[0049] In a preferred embodiment, such as Figure 2 As shown, the diameters of the multiple detection holes 131 on the vertical plate 13 are different, and the width of the first through hole 121 is greater than the maximum diameter of the detection hole 131.

[0050] In this embodiment, the multiple detection holes 131 on the vertical plate 13 have different diameters, which can be used to pass through detection pins of different diameters, thereby enabling the detection of machining holes of different diameters and improving the practicality of this application.

[0051] In a preferred embodiment, such as Figure 2 As shown, the inner fixing sleeve of the detection hole 131 is equipped with a wear-resistant sleeve.

[0052] In this embodiment, the diameter of the detection hole 131 can be protected by the wear-resistant sleeve. When the wear-resistant sleeve is damaged, the corresponding wear-resistant sleeve can be replaced instead of replacing the entire vertical plate 13, which can reduce the cost of equipment replacement.

[0053] In a preferred embodiment, such as Figure 3 As shown, the clamping mechanism 2 is provided with at least two sets, each including a fixed platform 21, a support plate 22, a second screw 23, a guide rod 24, a movable plate 25, and a clamping member 26. The support plates 22 are symmetrically arranged on the fixed platform 21, and the movable plate 25 is arranged between the two sets of support plates 22. One end of the second screw 23 is threaded through the support plate 22 and rotatably connected to the movable plate 25. The guide rod 24 slides through the support plate 22 and is fixedly connected to the movable plate 25. The end of the movable plate 25 away from the support plate 22 is provided with a clamping member 25. Rotating the second screw 23 can drive the clamping members 26 to move closer or further apart.

[0054] In this embodiment, at least two sets of clamping mechanisms 2 are provided. Since the pipe beam is a longitudinal structure, the arrangement of multiple sets of clamping mechanisms 2 can improve the stability of clamping and fixing the pipe beam.

[0055] When clamping the pipe beam, the pipe beam is placed on multiple sets of fixed platforms 21 for support. Then, the second screw 23 is rotated, which drives the moving plates 25 to move closer to each other. The guide rod 24 acts as a limit, causing the moving plates 25 to move closer to the pipe beam and not to rotate with the rotation of the second screw 23. The moving plates 25 drive the clamping parts 26 to clamp the pipe beam.

[0056] Preferred, such as Figure 3 As shown, the clamping member 26 includes multiple clamping plates 261 and multiple telescopic cylinders 262. The multiple clamping plates 261 are arranged sequentially along the length direction of the moving plate 25. Adjacent clamping plates 261 are hinged together. The telescopic cylinders 262 correspond one-to-one with the clamping plates 261. The piston rod of the telescopic cylinder 262 is hinged to the corresponding clamping plate 261. The telescopic cylinder 262 can extend and retract to drive the clamping plate 261 to rotate around the hinge connection, so as to adjust the angle between adjacent clamping plates 261 and make the multiple clamping plates 261 distributed with different arcs.

[0057] In this embodiment, the telescopic cylinder 262 can extend and retract, thereby causing multiple clamping plates 261 to rotate around the hinge connection, which in turn causes the multiple clamping plates 261 to form concave arc surfaces of different curvatures on the side close to the pipe beam. This allows for clamping of pipe beams of various diameters, making it applicable to a wide range of applications. It also fits the outer wall of the pipe beam better, resulting in more stable clamping.

[0058] In a preferred embodiment, such as Figure 3 As shown, the top surface of the fixed platform 21 is provided with multiple reference holes 211 for installing positioning pins.

[0059] In this embodiment, the top surface of the fixing platform 21 is provided with a reference hole 211, and the reference hole 211 is directly opposite the positioning hole on the tube beam. The positioning pin is inserted into the reference hole 211 for fixation, and then the tube beam is fixed by inserting the positioning pin into the positioning hole of the tube beam. While fixing the tube beam, the tube beam can be better positioned, which facilitates the subsequent detection of the hole position at the end of the tube beam and further improves the accuracy of the detection. In addition, multiple reference holes 211 are provided to meet the positioning of tube beams of various different specifications.

[0060] In a preferred embodiment, such as Figure 1 As shown, it also includes a base 6, a mounting frame 3 symmetrically arranged on the top surface of the base 6, and a clamping mechanism 2 also arranged on the top surface of the base 6.

[0061] In this embodiment, the fixing platform 21 and the mounting frame 3 of the clamping mechanism 2 are both detachably mounted on the top surface of the base 6 by bolts, so that they can be easily disassembled for repair when damaged.

[0062] In some embodiments, the fixed platform 21 of the clamping mechanism 2 can be driven to move horizontally by a translation drive device, and the mounting frame 3 can also be driven to move horizontally by a translation drive device, such as a lead screw drive or a rack and pinion drive, so that it can meet the requirements of clamping and inspecting pipe beams of different lengths.
