Description

Technical Field

[0001] The present application relates to the technical field of optical component detection, and more specifically, to a clamping fixture and device for detecting the end face of a cylindrical component. Background Art

[0002] Cylindrical components typically refer to cylindrical optical components with a large axial length and a small radial length. Cylindrical components typically require guaranteed end face shape and center deviation between the two end faces. Therefore, end face inspection of cylindrical components is necessary to ensure product quality.

[0003] Existing technology typically uses a horizontal inspection method for end face inspection of cylindrical parts. This involves laying the cylindrical part down with its axis aligned horizontally before conducting end face inspection. However, factories typically only have vertical inspection equipment, not horizontal equipment. This makes it difficult to inspect the end faces of cylindrical parts using existing vertical inspection equipment.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0046] Example 1

[0047] See also Figure 1 、 Figure 2 、 Figure 3 This embodiment proposes a clamping fixture for end face detection of cylindrical parts, which is used to install the cylindrical part 100 (rod-shaped part) on the mounting head 210 of the detection device 200. The detection device 200 is a vertical detection device 200, and the mounting head 210 can be a fixed structure. Among them, the clamping fixture of this scheme mainly includes a base 500. The outer contour of the base 500 can be circular. The base 500 is vertically installed on the mounting head 210, that is, the central axis of the base 500 after installation is set along the up and down direction. The base 500 and the mounting head 210 of the detection device 200 can be fixedly installed or relatively rotated, and adapted according to the driving method. A mounting hole 510 is provided on the base 500. The mounting hole 510 is a central axis hole. The open end of the mounting hole 510 faces upward, and a limited position surface 511 is provided in the mounting hole 510. Mounting hole 510 is used to insert cylindrical component 100, and is supported and restrained by limiting surface 511. Limiting surface 511 primarily supports cylindrical component 100 from below, limiting its vertical position and allowing it to be mounted on base 500. Mounting hole 510 of base 500 mates with the outer wall of cylindrical component 100. When cylindrical component 100 is inserted into mounting hole 510, the coaxiality between the central axis of cylindrical component 100 and the inspection standard axis of inspection device 200 does not exceed a set threshold, which may be 0.01 mm. This ensures coaxiality of no more than 0.01 mm, thus ensuring inspection accuracy.

[0048] This embodiment provides a clamping fixture for end face inspection of cylindrical parts. The base 500 can be vertically mounted on the mounting head 210, allowing the cylindrical part 100 to be inserted into the mounting hole 510. The cylindrical part 100 is supported and limited by the limiting surface 511 in the mounting hole 510, so that the cylindrical part 100 is limited to a predetermined height position in the mounting hole 510. After the cylindrical part 100 is installed in the mounting hole 510, the coaxiality between the central axis of the cylindrical part 100 and the inspection standard axis of the inspection device 200 is no more than 0.01 mm. When performing end face inspection on the cylindrical part 100, the cylindrical part 100 is rotatable on the mounting head 210, and the end face inspection of the cylindrical part 100 is achieved by the vertical inspection device 200. The end face shape of the cylindrical part 100 and the center deviation of the two end faces can be detected. Furthermore, during the end face inspection process of the cylindrical part 100, the clamping fixture facilitates the installation of the cylindrical part 100 and provides high positioning accuracy, thereby ensuring high inspection accuracy. Even in the absence of a horizontal inspection device 200, the vertical inspection device 200 can be used for inspection, which is more practical.

[0049] See also Figure 2 、 Figure 3 Furthermore, mounting hole 510 is a through hole, and a limiting surface 511 is disposed within the through hole to form a step within the through hole. Specifically, limiting surface 511 divides the through hole into two sections with different inner diameters. The upper portion of mounting hole 510 has a larger inner diameter, thereby being used to mount cylindrical component 100. The stepped surface serves as limiting surface 511, and the edge of the bottom end face of cylindrical component 100 abuts against limiting surface 511. Limiting surface 511 encloses the lower portion of mounting hole 510, thereby shielding the middle portion of the lower end face of cylindrical component 100 from air and preventing damage to the end face of cylindrical component 100.

[0050] See also Figure 1 、 Figure 2 、 Figure 3Furthermore, in this embodiment, a fastener 520 is provided on the outer wall of the base 500. The fastener 520 is inserted into the mounting hole 510 and presses against the side wall of the cylindrical component 100. Specifically, the outer wall of the base 500 is provided with multiple threaded holes, evenly distributed along the circumference. A plurality of fasteners 520 are provided correspondingly. Each of the fasteners 520 is threaded into each of the threaded holes and can be screwed into the mounting hole 510. The fasteners 520 on the base 500 move radially to adjust the upright position of the cylindrical component 100 within the base 500, ensuring that the central axis of the cylindrical component 100 is coaxial with the central axis of the base 500. The central axis of the base 500 can be set as the standard axis for testing of the testing device 200. This ensures that the central axis of the cylindrical component 100 is coaxial with the standard axis (the coaxiality is required to be within 0.01 mm), thereby ensuring the accuracy of detecting the deviation of the central axes of the two end faces of the cylindrical component 100.

[0051] The fastener 520 can be in various forms. For example, the fastener 520 includes a top screw that is screwed onto the outer wall of the base 500. The fastener 520 can also be a screw-connectable structure such as a screw.

[0052] See also Figure 2 、 Figure 3 Furthermore, in this embodiment, the length of the cylindrical component within the mounting hole is no longer than the length of the cylindrical component protruding from the mounting hole. Specifically, the length of cylindrical component 100 within mounting hole 510 is 30%-40% of the total length of cylindrical component 100. Inserting at least one-third of the total length of cylindrical component 100 into mounting hole 510 ensures a secure placement of cylindrical component 100.

[0053] See also Figure 2 、 Figure 3 、 Figure 4 Furthermore, the base 500 of this embodiment is connected to the mounting head 210 via an adapter 600. By installing the base 500 via the adapter 600, the base 500 can be installed on different vertical detection devices 200, with better adaptability and higher practicality.

[0054] See also Figure 1 、 Figure 2 、 Figure 3Furthermore, the base support 500 of this embodiment specifically includes: a support platform 530 and a vertical tube 540. The vertical tube 540 is arranged on the top of the support platform 530. The outer diameter of the support platform 530 is larger than the outer diameter of the vertical tube 540. The mounting hole 510 is located on the vertical tube 540. The adapter 600 specifically includes: an adapter platform 610 and a matching hole 620. The outer contour of the adapter platform 610 can be circular and is used to connect to the mounting head 210. The adapter 600 can be snapped onto the mounting head 210 of the detection device 200, thereby fixing the base support 500 and the mounting head 210 of the detection device 200 so that relative movement between them does not occur. The matching hole 620 is opened on the top of the adapter platform 610, and the support platform 530 is embedded and fixed in the matching hole 620. The outer wall of the support 530 and the matching hole 620 can be rotatably connected, so that the base 500 and the adapter 600 can be rotated, or the outer wall of the support 530 and the matching hole 620 can be fixed by interference fit; adapted according to the driving method.

[0055] See also Figure 2 、 Figure 3 Furthermore, a clearance hole 630 is provided at the bottom of the mating hole 620, thereby forming a step 621 at the bottom of the mating hole 620. This step 621 supports and limits the base 500. The clearance hole 630 is used to clear the detection light, allowing the detection light to vertically penetrate the cylindrical component 100 to achieve the detection function. In this embodiment, the single-side wall thickness of the adapter 610 at the clearance hole is 3mm; therefore, the single-side step width of the step 621 can be 2mm, and the outer wall thickness of the mating hole 620 can be 1mm, which ensures the structural strength of the outer wall of the mating hole 620.

[0056] Example 2

[0057] See also Figure 1 、 Figure 4 、 Figure 6 This embodiment provides an apparatus for inspecting the end faces of cylindrical parts, comprising an inspection device 200 and the aforementioned clamping fixture. During the inspection process, the cylindrical part 100 is rotated to perform end face inspection. The cylindrical part 100 can be rotated manually or with an external motor.

[0058] See also Figure 1 、 Figure 2 When manually rotating, cylindrical component 100 can be manually rotated within base 500. Base 500, adapter 600, and mounting head 210 of inspection device 200 must be securely fixed and prevent relative movement. Cylindrical component 100 then rotates within base 500, allowing inspection by inspection device 200.

[0059] When electric drive is adopted: it also includes a power device 300, which is set on the detection device 200, and provides driving force through the power device 300, so that the cylindrical part 100 on the base 500 rotates or the base 500 rotates.

[0060] See also Figure 4 、 Figure 6 The power device 300 specifically includes: a tightening mechanism 400, a rotating disk 320, and a driving assembly 310. In this embodiment, the left-right direction is the first direction. The tightening mechanism 400 is located on one side of the first direction of the mounting head 210 and is used to abut against the outer wall of the cylindrical part 100; the rotating disk 320 is rotatably arranged on the other side of the first direction of the mounting head 210, and the rotating disk 320 is used to drive the cylindrical part 100 to rotate; the driving assembly 310 is connected to the rotating disk 320, and the rotating disk 320 rotates by being driven by the driving assembly 310, thereby driving the cylindrical part 100 to rotate. The driving component 310 can use an electric motor to drive the pulley component 311 to drive the rotating disk 320. The rotating disk 320 is rotated by the drive component 310, and the side of the rotating disk 320 can abut against the side of the cylindrical part 100 or the outer wall of the base 500 to generate friction. Under the action of the friction force, the rotating disk 320 drives the clamping tool on the entire mounting head 210 to rotate, so that the cylindrical part 100 rotates automatically and at a uniform speed, thereby achieving stable detection.

[0061] The specific structure of the rotating disk 320 varies depending on the connection position of the rotating disk 320. The details are as follows:

[0062] See also Figure 4 、 Figure 5 In the first structure, when the rotating disk 320 drives the outer wall of the cylindrical part 100, the outer wall of the rotating disk 320 abuts against the outer wall of the cylindrical part 100, driving the cylindrical part 100 to rotate within the base 500. The rotating disk 320 specifically includes an upper abutting wheel 321 and a lower abutting wheel 322, which are spaced apart. The upper abutting wheel 321 and the lower abutting wheel 322 are both radially protruding. The upper abutting wheel 321 and the lower abutting wheel 322 abut against the outer wall of the cylindrical part 100 in the vertical direction. The pulley assembly 311 is connected between the upper abutting wheel 321 and the lower abutting wheel 322, thereby making the rotating disk 320 function as a pulley. The tightening mechanism 400 abuts against the cylindrical part 100 between the upper abutting wheel 321 and the lower abutting wheel 322. The pressing mechanism 400 is a prior art that only needs to achieve the function of pressing against the outer wall of the cylindrical component 100 through the V-shaped opening or the arc-shaped opening, and no structural description is given.

[0063] The cylindrical part 100 is vertically limited by the tightening mechanism 400 abutting against the outer wall of the cylindrical part 100 on the right and the rotating disk 320 abutting against the cylindrical part 100 on the left. The rotating disk 320 is driven by the drive assembly 310 to rotate. The side surfaces of the upper abutting wheel 321 and the lower abutting wheel 322 of the rotating disk 320 abut against the side surfaces of the cylindrical part 100, generating friction. Under the action of this friction, the rotating disk 320 drives the cylindrical part 100 to rotate on the base 500, achieving automatic and uniform rotation of the cylindrical part 100 and stable detection. At this time, the base 500, the adapter 600, and the mounting head 210 of the detection device 200 need to be installed and fixed. The jackscrews on the outer wall of the base 500 ensure the coaxiality of the cylindrical part 100 with the center axis of the base 500 within the base 500, with a coaxiality accuracy of 0.01mm. The right tightening mechanism 400 can move in the up and down directions to tighten the cylindrical component 100 at different height positions.

[0064] See also Figure 6 、 Figure 7 In the second structure, when the rotating disk 320 drives the outer wall of the base 500, the outer wall of the rotating disk 320 abuts against the outer wall of the base 500, driving the base 500 to rotate on the adapter 600. A friction portion 541 is provided circumferentially on the outer wall of the base 500. The rotating disk 320 includes a first abutting wheel 323, which abuts against the friction portion 541. The friction portion 541 can be vertical threads distributed along the circumference of the outer wall of the base 500, or other friction-enhancing structures such as bumps, bosses, etc. In this method, the pulley assembly 311 drives the rotating disk 320 to rotate, and the first abutting wheel 323 drives the base 500 and the cylindrical component 100 to rotate together within the adapter 600. The friction portion 541 is designed to increase the friction between the hub of the first abutting wheel 323 and the outer wall of the base 500. In this configuration, the adapter 600 and the mounting head 210 of the testing device 200 are securely fastened together, while the base 500, carrying the cylindrical component 100, rotates within the adapter 600. Similarly, the set screws on the outer wall of the base 500 improve the coaxiality between the central axis of the cylindrical component 100 and the base 500. This testing method also ensures that the coaxiality between the base 500 and the adapter 600 is within 0.01 mm.

[0065] In summary, the clamping fixture and device for cylindrical part end face inspection proposed in this application utilizes a base to achieve upright positioning of cylindrical parts, enabling end face inspection of cylindrical parts, including end face shape and center deviation at both ends. An adapter is also used to securely connect the base to the mounting head of the inspection device. This allows for end face inspection of cylindrical parts on vertical inspection equipment, achieving high positioning accuracy and improving inspection precision.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
