[0029] The utility model will be described in detail below.

[0030] As shown in Figures 1-5 :

[0031] A gear shaft blank reference surface automatic detection device, including base plate 1, install on base plate 1 and with base plate 1 along the X axle direction sliding fit's tight mechanism 2, fixedly installed on base plate 1 and be used for the rotation of the product to be measured rotation tight drive mechanism 3 of control, install on base plate 1 and be located between the support assembly of tight mechanism 2 and driving piece, install on base plate 1 and with base plate 1 sliding fit's angle detection tight mechanism 5, and install on base plate 1 and with base plate 1 sliding fit's positioning detection assembly 6;

[0032] The angle detection tight mechanism 5 is arranged opposite to the positioning detection assembly 6, and a detection cavity is formed between the two.

[0033] When detecting the reference surface 101, first, according to the size of the gear shaft blank 10, the angle detection tight mechanism 5 and the positioning detection assembly 6 are controlled to move along the Y-axis direction;The size of the detection cavity is adjusted so that the reference surface 101 of the gear shaft blank 10 can be located in the detection cavity;

[0034] Subsequently, the gear shaft blank 10 is installed on the support assembly 4, the tight mechanism 2 is controlled to move towards the side close to the rotation tight drive mechanism 3, and cooperates with the rotation tight drive mechanism 3 to effectively clamp and fix the gear shaft blank 10;

[0035] Then, the gear shaft blank 10 is controlled to rotate around its axis by the rotary jacking drive mechanism 3, and the angle formed by the reference plane 101 and the horizontal plane (the plane where the X-axis and the Y-axis are located) is measured by the angle detection jacking mechanism 5, so as to determine the rotation angle when the reference plane 101 is facing the positioning detection component 6. The reference plane 101 is facing the positioning detection component 6 when the reference plane 101 is vertically arranged on the plane formed by the X-axis and the Z-axis;

[0036] The gear shaft blank 10 is controlled to rotate around its axis according to the obtained rotation angle through the rotating tightening drive mechanism 3, so that the reference surface 101 is opposite to the end of the positioning detection component 6 close to the angle detection tightening mechanism 5, and the positioning detection component 6 is controlled to move toward the side close to the reference surface 101 and tighten the reference surface 101, so that the two are completely in fit; judge whether the moving distance of the positioning detection component 6 meets the requirements, if so, the reference surface 101 meets the requirements and the finished product can be processed; if not, no subsequent processing will be performed.

[0037] In some possible embodiments, in order to effectively cooperate with the rotary tightening drive mechanism 3 to achieve the clamping of gear shaft blanks 10 of different lengths; the tightening mechanism 2 includes a top driving cylinder 21 installed on the base 1 and slidingly cooperates with the base 1 along the X-axis direction, a tightening top 22 installed on the top driving cylinder 21, and a locking piece 23 for locking the top cylinder and the base 1.

[0038] The top driving cylinder 21 moves along the X-axis direction so that the distance between it and the rotary tightening driving mechanism 3 can meet the requirements for gear shaft blanks 10 of different lengths. When it moves to the required position, the top driving cylinder 21 is locked with the base 1 by the locking member 3 23 so that the top driving cylinder 21 no longer slides.

[0039] The tightening tip 22 can move along the X-axis direction under the control of the tip driving cylinder 21, so that one end of the tightening tip 22 close to the gear shaft blank 10 abuts against the gear shaft, and the other end abuts against the rotating tightening drive mechanism 3, thereby achieving clamping of the gear shaft blank 10.

[0040] In some possible embodiments, the angle detection and tightening mechanism 5 includes an angle detection component 51 and a sliding member 52 mounted on the base 1 and used to control the movement of the angle detection component 51 along the Y-axis direction; the angle detection component 51 is a prior art and can adopt a non-contact laser sensor;

[0042] The angle detection assembly 51 is mounted on the first sliding member 52, and the positioning head 61 is mounted on the second sliding member 62. By controlling the first sliding member and the second sliding member 62 to move closer to or further away from each other, gear shaft blanks 10 with different outer diameters can be tested, thereby determining the rotation angle when the reference surface 101 is facing the positioning angle detection and tightening mechanism 5;

[0043] The angle detection assembly 51 is provided so that the reference surface 101 of the gear shaft blank 10 clamped by the rotating and tightening driving mechanism 3 and the tightening mechanism 2 can be adjusted in angle, so that it can be rotated to a position facing the positioning detection assembly 6;

[0044] In some possible embodiments, in order to enable the angle detection assembly 51 and the positioning head 61 to be applicable to detection at different positions of the reference surface 101, the sliding member 52 includes a sliding seat 521 that slides with the base 1 along the X-axis direction, a support seat 522 that is mounted on the sliding seat 521 and slides with the sliding seat 521 along the Y-axis direction, a Y-axis driving member 523 for driving the support seat 522 to move along the Y-axis direction, and a locking member 1 for locking the sliding seat 521 and the base 1.

[0045] The second sliding member 62 includes a second sliding seat 621 that slides with the base 1 along the X-axis direction, a positioning cylinder 622 installed on the second sliding seat 621 and slidingly cooperates with the second sliding seat 621 along the Y-axis direction, a second Y-axis driving member 623 for driving the positioning cylinder 622 to move along the Y-axis direction, and a second locking member for locking the second sliding seat 621 and the base 1;

[0046] Specifically, when debugging the positioning detection assembly 6, the reference surface 101 of the finished gear shaft or the standard blank that meets the requirements is rotated to face the positioning head 61;

[0047] First, the positioning cylinder 622 is moved away from the finished gear shaft or the standard blank that meets the requirements by controlling the second Y-axis driving member 623;

[0048] Then, the positioning cylinder 622 controls the positioning head 61 to move toward the side close to the finished gear shaft or the standard blank that meets the requirements and extends to the limit position;

[0049] Then, the positioning head 61 is controlled by the second Y-axis driving member 623 to move toward the side close to the finished gear shaft or the standard blank that meets the requirements, so that the positioning head 61 is closely fitted with the reference surface 101;

[0050] The positioning head 61 is controlled by the positioning cylinder 622 to move away from the reference surface 101 and is in a retracted state;

[0051] Then, the positioning cylinder 622 is controlled by the second Y-axis driving member 623 to move toward the side close to the reference surface 101, and half of the telescopic stroke of the positioning cylinder 622 is moved to lock it; the telescopic stroke of the positioning cylinder 622 is the stroke of the positioning cylinder 622 controlling the movement of the positioning head 61; the positioning head 61 is controlled by the positioning cylinder 622 to move toward the side close to the reference surface 101 and abut closely to obtain the moving distance of the positioning head 61. Since it is in close contact with the reference surface 101 of the finished gear shaft or the standard blank that meets the requirements, the moving distance of the positioning head 61 will be used as a reference value to be compared with the moving distance of the positioning head 61 during the later inspection of the gear shaft blank 10;

[0052] When the gear shaft blank 10 is tested, the positioning cylinder 622 will no longer be controlled to move by the Y-axis driving member 2 623; the above-mentioned movement control method will ensure that the position sensor in the positioning cylinder 622 is in the position with the highest repeatability accuracy; the above-mentioned operation is mainly used for the initial debugging operation, and the positioning cylinder 622 will not be adjusted when the reference surface 101 of the same model is processed for testing later;

[0053] When testing the reference surface 101, the positioning head 61 is controlled by the positioning cylinder 622 to move toward the side close to the reference surface 101 to confirm that the workpiece reference surface 101 is correctly pressed and there is no gap; and it is determined whether the travel distance of the positioning head 61 at this time meets the requirements.

[0054] The Y-axis driving member 1 523 and the Y-axis driving member 2 623 have the same structure and are mainly used to control the support base 522 and the positioning cylinder 622 to perform linear motion in the Y-axis direction. Specifically, they can be installed using a linear driving structure in the prior art; for example, a lead screw structure, a linear electric push rod, etc. can be used.

[0055] When a lead screw structure is used for linear drive, the Y-axis driving member 1 523 or the Y-axis driving member 2 623 includes a lead screw that is arranged along the Y-axis direction and rotatably cooperates with the sliding seat 1 521 or the sliding seat 1 521, a lead screw nut that is sleeved on the outside of the lead screw and connected to the bottom of the support seat 522 or the positioning cylinder 622, a slide groove provided at the bottom of the support seat 522 or the positioning cylinder 622, a guide rail that is arranged along the Y-axis direction and slidably cooperates with the slide groove and is provided on the sliding seat 1 521 or the sliding seat 2 621, and a fastener for locking the support seat 522 and the sliding seat 1 521 or the positioning cylinder 622 and the sliding seat 2 621;

[0057] In some possible embodiments, the rotary tightening drive mechanism 3 includes a driving tip 31 having the same structure as the tightening tip 22 and mounted on the base 1, and a rotary driving member 32 connected to the driving tip 31 and used to control the driving tip 31 to rotate around the X-axis direction;

[0058] The rotation drive assembly is a drive motor; specifically, a servo motor can be used; based on the rotation angle information detected by the angle detection and tightening mechanism 5, the servo motor controls the driving center 31 to rotate around the X-axis direction, thereby rotating the gear shaft blank 10 around the X-axis direction, so that the reference surface 101 is facing the positioning head 61;

[0059] The end face of the positioning head 61 close to the gear shaft blank 10 is a vertical plane. When the reference surface 101 faces the positioning head 61, the positioning head 61 can be moved so as to completely fit with the reference surface 101 without any gap.

[0060] In some possible embodiments, the driving tip 31 and the tightening tip 22 are conical and coaxially arranged, and the small ends of the driving tip 31 and the tightening tip 22 are arranged close to each other;

[0061] Both ends of the gear shaft blank 10 are provided with holes, and the axes of the two sets of holes are coaxially arranged with the axis of the gear shaft. The driving top 31 and the tightening top 22 will be inserted into the corresponding holes when clamping, so as to support and clamp the gear shaft blank 10.

[0062] In some possible embodiments, a slide rail 11 and a slide rail 2 12 are provided on the base 1 and are slidably engaged with the tightening mechanism 2 and are arranged along the X-axis direction; a mounting groove is formed between the slide rail 11 and the slide rail 2 12, and the support assembly 4 is provided in a plurality of groups and is arranged in the mounting groove along the X-axis direction;

[0063] The angle detection and tightening mechanism 5 is slidably matched with the slide rail 11, thereby realizing the movement of the angle detection and tightening mechanism 5 along the X-axis direction, and adjusting the position of the angle detection component 51 in the X-axis direction according to the position of the reference surface 101; the positioning detection component 6 is slidably matched with the slide rail 2 12, and the positioning head 61 can be adjusted according to the position of the reference surface 101 in the X-axis direction; through the above, the present device can be applied to the testing of different types of gear shaft reference surfaces 101, making its scope of application wider.

The bracket 41 is provided with threaded holes. Screws are passed through different through holes and matched with the threaded holes on the bracket 41 to achieve the bracket 41 being installed at different positions on the bottom plate.

[0066] The V-shaped frame 42 slides with the bracket 41 in the Z-axis direction, and a Z-direction slide groove is provided in the bracket 41. A sliding part that slides with the slide groove is provided at the bottom of the V-shaped frame 42, and a waist-shaped hole with a long axis arranged along the Z-axis direction is provided in the sliding part; the sliding part is connected to the bracket 41 by bolts, so that the gear shaft blanks 10 with different outer diameters can be supported; after the rotating tightening drive mechanism 3 and the tightening mechanism 2 clamp the gear shaft blank 10, the V-shaped frame 42 will no longer support the gear shaft blank 10; this avoids friction interference between the V-shaped frame 42 and the gear shaft blank 10 during rotation.
