Description

Technical Field

[0001] This utility model relates to the field of swivel head measuring tool technology, specifically a swivel head spindle pull claw hole measuring tool. Background Technology

[0002] A swivel head is a multi-axis functional component whose tool power output can rotate with the swivel axis. It is a core component of multi-axis linkage machine tools such as gantry machining centers and mill-turn machining centers. As a key component for tool power output, the precision and performance of the swivel head spindle directly determine the machining quality of the workpiece. The part in the spindle's inner hole used to install the pull claw is a critical structure that has a profound impact on the tool clamping accuracy, clamping stability, and tool changing efficiency.

[0003] Common methods for measuring spindle pull-aper holes mainly rely on the use of tools such as inside micrometers and depth calipers. During inspection, the inside micrometer must first be inserted into the spindle pull-aper hole, and the position of the measuring contact is adjusted by feel and experience to obtain the hole diameter data. For the depth information of the pull-aper hole, the reference surface of the caliper needs to be placed against the corresponding position on the spindle end face, and the measuring rod is slowly inserted to read the depth value.

[0004] However, the above-mentioned detection methods are extremely cumbersome to operate, requiring inspectors to frequently switch measuring tools and meticulously adjust the measurement position. This is not only time-consuming and labor-intensive with poor detection efficiency, but also places high demands on the operator's skills and experience. Human factors have a significant impact on the measurement results, making it difficult to guarantee the repeatability and accuracy of measurements under different operators. At the same time, due to the relatively confined internal space of the spindle pull-claw hole, the operational flexibility of traditional measuring tools is limited. When measuring some special parts, such as near the edge of the hole wall or the step inside the hole, it is difficult to accurately locate the position, and it is easy to miss key measurement points, resulting in a large deviation in the measurement results. Therefore, it cannot fully reflect the true dimensional accuracy of the pull-claw hole. Based on this, a swivel spindle pull-claw hole measuring tool is now provided, which can eliminate the drawbacks of the existing device. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] In one embodiment, such as Figures 1-5 As shown, a swivel head spindle pull claw hole measuring tool includes a tapered bar 1, a tapered bar head 3 fixedly connected to one end of the tapered bar 1, a measuring template 4 disposed inside the tapered bar head 3, the measuring template 4 penetrating through the tapered bar head 3 to the interior of the tapered bar 1, grooves 5 for sliding of the measuring template 4 being provided on both the tapered bar 1 and the tapered bar head 3, a measuring block integrally formed at the top end of the measuring template 4 away from the tapered bar 1, a limit plate integrally formed at the top end of the measuring template 4 away from the measuring block, and a limit mechanism for connecting and limiting the measuring template 4 on the tapered bar 1;

[0038] The limiting mechanism includes: a limiting rod 201 disposed inside the tapered rod 1, the limiting rod 201 being slidably connected to the tapered rod 1 and the tapered rod head 3, and the measuring template 4 being slidably sleeved on the outer wall of the limiting rod 201;

[0039] The limiting mechanism also includes:

[0040] A first moving component is mounted on the tapered bar 1;

[0041] The first moving component is a limiting slide plate 203 set inside the tapered rod 1. The limiting slide plate 203 is located below the measuring template 4 and is slidably connected to the tapered rod 1 and the tapered rod head 3.

[0042] The limiting rod 201 is equipped with a locking component for pressing and locking the measuring template 4;

[0043] The limiting slide plate 203 is provided with a support component for moving and supporting the limiting rod 201;

[0044] The limiting slide plate 203 is provided with a second moving component for limiting movement;

[0045] In this embodiment, during use, the tapered rod 1, tapered rod head 3 and measuring template 4 can be easily connected by the limiting rod 201, and then the measuring template 4 can be easily locked and limited by the limiting mechanism, so that the tapered rod 1, tapered rod head 3 and measuring template 4 can be easily carried.

[0046] When in use, push the measuring template 4 to slide along the inner wall of the groove 5. At this time, the measuring template 4 can be moved and limited by the limiting mechanism. When measuring the spindle pull claw hole, the measuring template 4, measuring block, tapered rod 1, tapered rod head 3 and limiting plate cooperate with each other to detect the hole diameter of the pull claw hole.

[0047] When the inspection of the pull claw hole is completed, the above operation is reversed. The measuring template 4 can be easily replaced according to the actual situation, thereby further improving the efficiency of the pull claw hole inspection.

[0048] In one embodiment, such as Figures 1-5 As shown, the locking assembly is a locking sleeve 202 sleeved on one side of the outer wall of the limiting rod 201. The locking sleeve 202 is in contact with one side of the outer wall of the measuring template 4. The locking sleeve 202 is threadedly connected to the limiting rod 201. The locking sleeve 202 is slidably connected to the tapered rod 1 and the tapered rod head 3. The locking sleeve 202 can squeeze and limit the measuring template 4, effectively preventing the measuring template 4 from separating from the tapered rod 1 and the tapered rod head 3 during the carrying process.

[0049] In one embodiment, such as Figures 2-5 As shown, the support component is a support slider 204 fixedly connected to the top of the limiting slide plate 203. The support slider 204 is fixedly connected to the limiting rod 201, and the support slider 204 is slidably connected to the tapered rod 1 and the tapered rod head 3.

[0050] The second moving component includes: a connecting slider 206 fixedly connected to the bottom end of the limiting slide plate 203; two sets of moving rollers 205 are symmetrically rotatably connected to the outer wall of the connecting slider 206; and linear grooves are provided on the tapered rod 1 and the tapered rod head 3 for the connecting slider 206 and the moving rollers 205 to move. Through the cooperation between the support component and the second moving component, the measuring template 4 can be moved and limited.

[0051] A limit component is provided on the tapered rod 1;

[0052] In one embodiment, such as Figures 3-5 As shown, the limiting component is a limiting baffle 208 that is slidably connected inside the tapered rod 1, and the limiting baffle 208 is located below the connecting slider 206;

[0053] The limit baffle 208 is provided with a positioning component for engaging and positioning the connecting slider 206;

[0054] The limit baffle 208 is provided with a reset component for pushing the limit baffle 208 to reset;

[0055] The positioning component is a positioning block 207 set inside the tapered rod 1. The top outer wall of the positioning block 207 is hemispherical. The positioning block 207 penetrates through the tapered rod 1 to the interior of the connecting slider 206.

[0056] The reset component is a spring 209 located at the bottom of the limiting baffle 208. One end of the spring 209 contacts the outer wall of the limiting baffle 208, and the other end of the spring 209 contacts the inner wall of the tapered rod 1. Through the cooperation of the limiting component, the positioning component and the reset component, the connecting slider 206 can be engaged and positioned, effectively preventing the measuring sample 4 from sliding randomly along the inner wall of the groove 5 during the carrying process.

[0057] The above embodiment discloses a swivel spindle pull claw hole measuring tool. In use, the measuring template 4 is pushed to fit onto the outer wall of the limiting rod 201 until the measuring template 4 moves to the opening of the groove 5. Then, the measuring template 4 is flipped around the limiting rod 201 as the axis until the measuring template 4 is flipped into the inner cavity of the groove 5. This allows for convenient docking of the tapered rod 1, the tapered rod head 3 and the measuring template 4.

[0058] Then, rotate the locking sleeve 202 to connect the outer wall of the limiting rod 201 with a thread until the locking sleeve 202 contacts the outer wall of the measuring template 4. This allows for convenient locking and limiting of the measuring template 4, and makes it convenient to carry the tapered rod 1, the tapered rod head 3, and the measuring template 4.

[0059] In use, the measuring template 4 is pushed to slide along the inner wall of the groove 5. At this time, the supporting slider 204, driven by the measuring template 4 through the limiting rod 201, drives the connecting slider 206 to move through the limiting slide plate 203. Simultaneously, the connecting slider 206 moves along the inner wall of the tapered rod 1 and the tapered rod head 3 in sequence through the moving roller 205 until the connecting slider 206 contacts the inner wall of one end of the tapered rod head 3. During this process, the positioning block 207, under the pressure of the connecting slider 206, pushes the limiting baffle 208 down along the inner wall of the tapered rod 1. At the same time, the limiting baffle 208 retracts through the moving compression spring 209. When the connecting slider 206 and the outer wall of the positioning block 207 separate from each other, the spring 209 pushes the limiting baffle 208 to slide back to its original position through rebound, thereby releasing the locking and positioning of the connecting slider 206.

[0060] When measuring the spindle puller hole, the measuring template 4 is pushed to insert the measuring block into the spindle puller hole, and the measuring template 4 is pushed to make the outer wall of the measuring block contact the inner wall of the puller hole. Then, the tapered bar 1 is pushed to make the tapered bar head 3 insert into the inner cavity of the puller hole along the outer wall of the measuring template 4. In this way, the diameter of the puller hole can be detected.

[0061] During this process, if the diameter of the pull claw hole is qualified, the outer wall of the tapered bar head 3 and the measuring block will be tightly fitted with the inner wall of the pull claw hole, and the measuring template 4 cannot be pulled to move. If the diameter of the pull claw hole is too small, the outer wall of the measuring block cannot be tightly fitted with the inner wall of the pull claw hole, and the tapered bar head 3 cannot be fully inserted into the inner cavity of the pull claw hole. If the diameter of the pull claw hole is too large, when the outer wall of the measuring block contacts the inner wall of the pull claw hole, a certain gap will be generated between the measuring block and the pull claw hole. At this time, the measuring template 4 is pulled to move back and forth along the inner wall of the groove 5. At this time, the movement range of the limit plate can be detected by measuring the gap between the limit plate and the tapered bar head 3.

[0062] When the inspection of the pull claw hole is completed, the above operation is reversed. The measuring template 4 can be easily replaced according to the actual situation, thereby further improving the efficiency of the pull claw hole inspection.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
