[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 7 A conical shaft surface inspection tool has a loading station, an inspection station, an unloading station and a waiting station. The inspection station is used to install a linear moving module with a laser scanner. The laser scanner moves axially along the conical shaft 14 through the linear moving module. The conical surface of the conical shaft 14 is scanned by the laser scanner to obtain a conical surface image for conical surface inspection.

[0031] The tapered shaft surface detection tooling includes a support ring 1 and a mounting ring 2. The support ring 1 is T-shaped, and the end with a smaller diameter on the support ring 1 is the small end, and the end with a larger diameter on the support ring 1 is the large end. The mounting ring 2 is sleeved on the outer circumferential surface of the lower end of the support ring 1 through its inner hole and contacts the top surface of the large end of the support ring 1. A driving unit 2 13 is fixed on the top surface of the support ring 1, and a gear ring 12 is coaxially fixed on the top surface of the mounting ring 2. The driving unit 2 13 is used to drive the gear ring 12 to rotate so that the mounting ring 2 can rotate. The rotation direction of the mounting ring 2 is as follows: Figure 7 Indicated by the thin solid arrow.

[0032] The loading station, the inspection station, the unloading station and the waiting station are distributed at intervals along the rotation direction of the mounting ring 2 .

[0033] The tapered shaft surface detection tooling also includes a fixture 3, a positioning assembly 4, a slide 5, a drive block 6, a linkage 7, a drive unit 8, a rack 9, a gear 10 and a mounting plate 11;

[0034] The clamp 3 is provided with a plurality of clamps 3 and the plurality of clamps 3 are evenly spaced along the circumferential direction and installed on the mounting ring 2; the clamp 3 has a clamping portion for clamping the tapered shaft 14; the clamping portion of the clamp 3 has a clamping state and an open state, and in the clamping state, the clamp 3 can clamp the tapered shaft 14, and in the open state, the clamp 3 cannot clamp the tapered shaft 14;

[0035] There are multiple positioning components 4, and the multiple positioning components 4 are installed in pairs at the top of the mounting ring 2 and cooperate with the multiple clamps 3; the positioning components 4 are used to keep the clamps 3 in a clamped state or an open state;

[0036] A pair of slides 5 are provided and located between the plurality of clamps 3. The slides 5 are radially slidably mounted on the top of the support ring 1. The clamps 3 are switched between the open state and the clamped state by sliding the slides 5 toward the clamps 3. A return spring 53 is installed between the slides 5 and the mounting ring 2 to drive the slides 5 to move radially away from the clamps 3. The ends of the two slides 5 that are away from each other point to the loading station and the unloading station respectively.

[0037] The drive block 6 is disposed between the two slides 5. An isosceles trapezoidal groove capable of cooperating with the slides 5 is formed at opposite ends of the drive block 6. The drive block 6 can be driven by a drive unit 8 fixed to the support ring 1 and moved axially along the mounting ring 2. Through the axial movement of the drive block 6, the two slides 5 can move away from each other and drive the two clamps 3 located in their sliding directions to move, causing the two clamps 3 to respectively clamp the tapered shaft 14 and open and release the tapered shaft 14.

[0038] The linkage member 7 is fixedly mounted on the driving block 6 and has a telescopic end. The telescopic end can contact and cooperate with the clamp 3 moved to the unloading station. When the telescopic end contacts the clamp 3, the axial movement of the driving block 6 is transmitted to the clamp 3 matched therewith, so that the clamping part of the clamp 3 moves axially.

[0039] The rack 9 and the gear 10 are provided as a set and together form a rotating assembly; two sets of racks 9 and gears 10 are installed on one clamp 3; when the clamping part of the clamp 3 moves axially, it drives the gear 10 to move axially and rotate, thereby switching the clamping part between a horizontal state and a vertical state;

[0040] A pair of mounting plates 11 are provided and located at the detection station. The opposite surfaces of the two mounting plates 11 are respectively used to mount a linear motion module with a laser scanner.

[0041] When the conical surface of the conical shaft 14 is inspected, the conical shaft 14 before inspection is fed into the loading station in a vertical state, and the conical shaft 14 after inspection is fed out of the unloading station in a vertical state or a horizontal state.

[0042] Before testing the tapered surface of the tapered shaft 14 , the clamping parts of each clamp 3 are adjusted to a horizontal state, and the clamping part of one clamp 3 is adjusted to an open state, and the clamping parts of the remaining clamps 3 are adjusted to a clamping state.

[0043] When the mounting ring 2 rotates and drives the clamp 3 in the open state to move to the loading station, the driving unit 18 drives the driving block 6 to move upward, so that the two inclined surfaces on the lower sides of the two isosceles trapezoidal grooves move up respectively to move with the two slides 5, pushing the two slides 5 away from each other and moving to the loading station and the unloading station respectively, compressing the two return springs 53, pushing the clamp 3 at the loading station and the clamp 3 at the unloading station to move, so that the clamp 3 at the loading station switches from the open state to the clamping state, clamping the vertical tapered shaft 14, and the corresponding positioning component 4 keeps the clamp 3 in the clamping state, so that the clamp 3 at the unloading station switches from the clamping state to the open state, and the corresponding positioning component 4 keeps the clamp 3 in the open state, and then, the driving unit 18 drives the driving block 6 to move downward, and the two return springs 53 reset and push the two slides 5 closer to each other.

[0044] Then, the mounting ring 2 continues to rotate, so that the fixture 3 at the loading station moves to the detection station, the tapered shaft 14 is moved between the two laser scanners, the tapered surface of the tapered shaft 14 is detected, and the fixture 3 at the waiting station is moved to the loading station.

[0045] After completing the conical surface inspection of the tapered shaft 14, the mounting ring 2 continues to rotate, so that the fixture 3 and the tapered shaft 14 are moved to the unloading station. Then, the sliding direction of the driving block 6 when driving the slide 5 is selected according to the inspection result of the tapered shaft 14. That is, when the conical surface inspection of the tapered shaft 14 is qualified, the driving unit 18 drives the driving block 6 to move upward, so that the two inclined surfaces on the lower sides of the two isosceles trapezoidal grooves move upward respectively, pushing the two slides 5 to slide and move away from each other, so that the fixture 3 at the loading station closes and clamps the tapered shaft 14, and the fixture 3 at the unloading station opens and releases the tapered shaft 14, so that the tapered shaft 14 is separated from the fixture in a vertical state.

[0046] When the conical surface of the tapered shaft 14 fails to pass the inspection, the driving unit 18 drives the driving block 6 to move downward, the linkage 7 moves downward, pushes the clamping part of the clamp 3 at the blanking station and the tapered shaft 14 downward, and cooperates with the rotating assembly to rotate the clamping part from the horizontal state to the vertical state, so that the tapered shaft 14 rotates from the vertical state to the horizontal state, and then, the telescopic end of the linkage 7 is separated from the clamp 3, after which the driving block 6 continues to move downward so that the two inclined surfaces on the upper sides of the two isosceles trapezoidal grooves contact the two slides 5 respectively, pushing The two slides 5 slide and move away from each other, compressing the two return springs 53, so that the clamp 3 at the loading station closes and clamps the conical shaft 14, and the clamp 3 at the unloading station opens and releases the conical shaft 14, so that the conical shaft 14 disengages. After that, the telescopic end of the linkage 7 cooperates with the clamp 3 at the unloading station again, and the drive unit 8 drives the drive block 6 to move upward, so that the clamping part of the clamp 3 at the unloading station moves up and rotates to a horizontal state, and the two return springs 53 push the two slides 5 to move closer to each other.

[0047] Then, the mounting ring 2 continues to rotate, moving the fixture 3 at the loading station to the waiting station. By rotating the mounting ring 2 in this way, the cyclic movement of each fixture 3 between the loading station, the inspection station, the unloading station and the waiting station is achieved. By configuring the drive block 6 to be able to drive the two slides 5 away from each other by moving upward, thereby driving the clamping of the fixture 3 at the loading station and the opening of the fixture 3 at the unloading station, and being able to drive the clamping part of the fixture 3 at the unloading station to rotate by moving downward, the conical shaft 14 at the unloading station is moved downward and rotated from a vertical state to a horizontal state, and then the clamping of the fixture 3 at the loading station and the opening of the fixture 3 at the unloading station are driven, thereby achieving continuous detection of the conical surfaces of batches of conical shafts 14, and enabling the conical shafts 14 with different detection results to be separated from the tooling in different states, and realizing automatic classification of the conical shafts 14 according to the detection results, while improving the detection efficiency and avoiding the mixing of conical shafts 14 with different detection results.

[0048] It should be noted that, in the above technical solution, the linkage member 7 is any one of a pneumatic cylinder, a hydraulic cylinder or an electric push rod.

[0049] It should be noted that, in the above technical solution, the driving unit 8 is a power device used in the prior art for outputting linear movement, such as a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0050] It should be noted that, in the above technical solution, the second drive unit 13 is a combination of a motor and an internal gear, the motor housing is fixed to the top surface of the support ring 1 , and the internal gear is meshed with the ring gear 12 .

[0051] As a further explanation of the above technical solution, Figure 3 、 Figure 4 and Figure 7As shown, the clamp 3 includes two rotating sleeves 31, two follower rods 32, two rotating shafts 321, two clamping rods 33, two displacement blocks 34, two spring columns 35 and a linkage rod 36; the two clamping rods 33 together constitute the clamping portion of the clamp 3;

[0052] The two rotating sleeves 31 axially penetrate and are rotatably connected to the mounting ring 2; the follower rod 32 is a T-shaped rod, with the end with a smaller diameter as the small end and the end with a larger diameter as the large end. The two small ends axially penetrate and are slidably connected to the two rotating sleeves 31, and the ends of the two large ends away from the small ends are rotatably connected to the two clamping rods 33 via two rotating shafts 321. A transposition block 34 is fixed to the outer circumference of each of the two rotating sleeves 31.

[0053] The transposition block 34 has a driving surface 1 341, a driving surface 2 342 and a stabilizing surface 343. The driving surface 1 341, the driving surface 2 342 and the stabilizing surface 343 are all vertical surfaces of the transposition block 34. The driving surface 1 341 and the driving surface 2 342 are on the same vertical plane and are both connected to the outer circumferential surface of the rotating sleeve 31. The stabilizing surface 343 is located between the driving surface 1 341 and the driving surface 2 342, and the stabilizing surface 343 is close to the driving surface 1 341 and is arranged at a 45-degree angle to the driving surface 1 341. Figure 7 As shown;

[0054] The two spring columns 35 are respectively embedded in the two rotating sleeves 31, and the movable ends of the two spring columns 35 are pluggably connected to the small ends of the two follower rods 32; when the clamping rod 33 is needed to clamp the tapered shaft 14, the movable end of the spring column 35 is embedded in the follower rod 32.

[0055] The ends of the small ends of the two follower rods 32 away from the large ends are equipped with a linkage rod 36 through an axis that rotates together. The top and bottom surfaces of the linkage rod 36 alternately contact and cooperate with the moving end of the linkage member 7 to realize the transmission cooperation between the linkage rod 36 and the moving end of the linkage member 7; through the transmission cooperation between the linkage rod 36 and the moving end of the linkage member 7, the axial movement of the driving block 6 is transmitted to the two follower rods 32 in the same clamp 3, so that the two follower rods 32 can move axially with the axial movement of the driving block 6, and when the top surface of the linkage rod 36 contacts and cooperates with the moving end of the linkage member 7, the follower rod 32 can move axially downward, and when the bottom surface of the linkage rod 36 contacts and cooperates with the moving end of the linkage member 7, the follower rod 32 can move axially upward.

[0056] like Figure 3 and Figure 7As shown, multiple positioning assemblies 4 correspond one-to-one with multiple transposition blocks 34. The positioning assembly 4 includes a fork-shaped rod 41 and a pressure spring 42. The fork-shaped rod 41 is composed of a prism and a C-shaped frame. The prism is slidably mounted on the top of the mounting ring 2. The pressure spring 42 is sleeved on the prism between the mounting ring 2 and the C-shaped frame and is in a compressed state. The pressure spring 42 is used to press the C-shaped frame of the fork-shaped rod 41 against the driving surface 341 on the transposition block 34, so that the force component acting on the transposition block 34 can be used to maintain the clamping rod 33 in the clamped state, or press against the stabilizing surface 343 on the transposition block 34, so that the force acting on the transposition block 34 can be radially perpendicular to the transposition block 34, thereby maintaining the clamping rod 33 in the open state.

[0057] like Figure 5 、 Figure 6 and Figure 7 As shown, the slide 5 includes a transmission block 51 radially slidably mounted on the top of the support ring 1, and the end of the transmission block 51 away from the driving block 6 is detachably fixedly connected to the transmission column 52, and the vertical cross-section of the end of the transmission block 51 facing the driving block 6 is a right-angled isosceles triangle, and cooperates with the isosceles trapezoidal groove on the driving block 6; the end of the transmission block 51 away from the driving block 6 is fixedly connected to the reset spring 53.

[0058] The transposition blocks 34 in the two clamps 3 located in the sliding direction of the pair of slides 5 can be pushed by the sliding slides 5 to rotate, so that the two clamps 3 can respectively clamp the tapered shaft 14 and open and release the tapered shaft 14; the details are as follows:

[0059] When the slide 5 pushes the fixture 3 at the loading station to clamp the tapered shaft 14, the two transmission posts 52 in the slide 5 respectively contact the two driving surfaces 341, so that the two transposition blocks 34 respectively move along the Figure 7 The rotation direction indicated by the thick solid arrow causes the rotating sleeve 31 and the follower rod 32 to rotate, driving the two clamping rods 33 to clamp the tapered shaft 14. After the clamping rods 33 clamp the tapered shaft 14, the C-shaped frame of the fork-shaped rod 41 presses against the driving surface 341, as shown in FIG. Figure 7 As shown;

[0060] When the slide 5 pushes the clamp 3 at the blanking station to open, the two transmission posts 52 in the slide 5 contact the two driving surfaces 342 respectively, driving the two transposition blocks 34 to move along the Figure 7 The rotation direction indicated by the dotted arrow rotates the rotating sleeve 31 and the follower rod 32, driving the two clamping rods 33 to open. After the two clamping rods 33 are opened, the C-shaped frame of the fork rod 41 presses against the stable surface 343, as shown in FIG. Figure 7 shown.

[0061] As a further explanation of the above technical solution, Figure 3 and Figure 4As shown, the rack 9 in the rotating assembly is fixed to the bottom end of the rotating sleeve 31, and the gear 10 is fixed to the rotating shaft 321; when the clamping rod 33 of the clamp 3 moves axially, the rotating shaft 321 moves axially along the mounting ring 2 and drives the gear 10 to move and roll on the rack 9, thereby driving the rotating shaft 321 to rotate, causing the clamping rod 33 to rotate around the rotating shaft 321, and then the clamping rod 33 can switch between the horizontal state and the vertical state during the axial movement; at the blanking station, the conical shaft 14 can be switched from the vertical state to the horizontal state by moving the clamping rod 33 and the conical shaft 14 downward and rotating around the rotating shaft 321.
