Description

Technical Field

[0001] This utility model belongs to the technical field of indexing chuck detection device, specifically an indexing chuck micro-motion detection device. Background Technology

[0002] In fields such as machining, it is necessary to precisely rotate workpieces to different angles so that the cutting device can process different positions of the workpiece. Using an indexing chuck can help the workpiece achieve more precise angle conversion and positioning, ensuring the accuracy of machining.

[0003] Indexing chuck micro-motion detection refers to adjusting the rotation angle of the indexing chuck and ensuring the precision and accuracy of the rotation angle when using it.

[0004] When detecting the micro-motion of an indexing chuck, the probe of a dial indicator is typically placed against the outer surface of the chuck, and the runout value on the dial indicator is read by rotating the chuck to detect the micro-motion. However, the dial indicator can only detect the rotational accuracy of the outer surface of the chuck. The chuck clamps and fixes the workpiece, causing the workpiece to rotate as well. The rotational accuracy of the clamps also needs to be detected. Since the shape of the clamps is irregular, the dial indicator is not suitable for micro-motion detection. Therefore, to address the above problems, a micro-motion detection device for an indexing chuck is proposed. Utility Model Content

[0009] Preferably, the top of the placement tray has a positioning hole, and the bottom of the positioning post is inserted into the positioning hole.

[0010] Furthermore, a cap is installed on the top of the positioning post. After the positioning post is inserted into the positioning hole from the insertion interface, the cap on the top of the positioning post will abut against the top of the abutment plate, and the abutment plate will abut against the top of the chuck body.

[0011] Preferably, three clamping components are provided, and the three clamping components are arranged in a circumferential array on the outer surface of the chuck body to limit and fix the chuck body to the top of the placement tray.

[0012] Furthermore, three clamping components are installed on the top of the placement tray, and three positioning holes are opened on the top of the placement tray, with the positions of the three positioning holes corresponding to the positions of the three positioning posts.

[0013] Preferably, the connecting assembly includes a drive motor installed inside the mounting port and a collar fixedly installed on the top of the testing platform. A connecting plate is fixedly installed on the top of the collar, and a rotating interface is provided on the top of the connecting plate.

[0014] Preferably, the rotating disk is fixedly installed at the bottom of the placement tray, and the rotation of the rotating disk can drive the placement tray to rotate together.

[0015] Preferably, a control panel is installed on the top of the testing platform, which is used to control the start and stop of the drive motor and the electric push rod.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, when the drive motor is energized, the chuck body placed on top of the disc rotates. The clamping component is held by the clamping block of the chuck body and rotates together. The detection disc two is rotatably connected to the clamping component. The detection disc two and the detection disc one do not rotate together with the clamping component. When the rotation angle of the chuck body deviates, the inner wall of the clamping block will rub against the detection rubber ring two sleeved on the outer surface of the detection disc two. This indicates that the rotation accuracy of the chuck body is unqualified. The detection disc one is located on top of the clamping block of the chuck body. When the clamping block is not installed on the top of the chuck body, the clamping block will also rub against the detection rubber ring one, achieving the effect of detecting the micro-motion of the chuck body.

[0018] 2. In this utility model, the chuck body is placed inside the three arc-shaped plates, the abutment plate is rotated to abut the top of the chuck body, and the bottom of the positioning pin is inserted into the positioning hole.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, a micro-motion detection device for an indexing chuck includes a detection table 1. The top of the detection table 1 has an installation port, and a connecting component 11 is installed inside the installation port. A placement plate 2 is fixedly installed on the top of the connecting component 11. A chuck body 21 is provided on the top of the placement plate 2. A clamping component 22 is installed on the top of the placement plate 2. A detection component 3 is installed on the top of the detection table 1.

[0029] The detection assembly 3 includes two support plates 301 fixedly installed on the left and right sides of the top of the detection table 1. The top of the two support plates 301 is fixedly installed with a mounting plate 302. The bottom of the mounting plate 302 is fixedly installed with an electric push rod 303. The bottom of the electric push rod 303 is fixedly installed with a detection disc 304. The bottom of the detection disc 304 has a bayonet. The inside of the bayonet is installed with a detection rubber ring 305. The bottom of the detection disc 304 is fixedly installed with a detection disc 306. The outer surface of the detection disc 306 is fitted with a detection rubber ring 307. The bottom of the detection disc 306 is fixedly installed with a connecting rod 308. The bottom of the connecting rod 308 is rotatably installed with a clamping member 309.

[0030] The top of the testing station 1 is equipped with a control panel 5, which is used to control the start and stop of the drive motor 101 and the electric push rod 303.

[0031] Through the above technical solution, the mounting plate 302 is fixedly installed on the top of the two support plates 301 on the top of the testing table 1, so that the electric push rod 303 can be installed on the bottom of the mounting plate 302 for fixation. The output shaft of the electric push rod 303 is fixedly installed on the top of the first testing plate 304. A bayonet is opened on the bottom side of the first testing plate 304 so that the first testing rubber ring 305 can be installed inside the bayonet. The second testing plate 306 is fixedly installed on the bottom of the first testing plate 304. The bottom of the second testing plate 306 is rotatably installed with a clamp via the connecting rod 308. Component 309: Pressing the button on the control panel 5 energizes the electric push rod 303, causing its output shaft to extend to different lengths. When performing micro-motion detection on the chuck body 21, which is fixed in place by the clamping assembly 22, the electric push rod 303 pushes the detection disc 304 to the top of the clamping block of the chuck body 21. At this time, the detection rubber ring 305 is also at the top of the clamping block of the chuck body 21. The detection disc 306 at the bottom of the detection disc 304 and the clamping component 309 will then enter the clamping block of the chuck body 21. Inside the chuck body 21, activating the chuck body 21 allows the clamping blocks to hold the clamping member 309. The diameter of the detection disc 306 is smaller than the diameter of the clamping member 309. Before the detection disc 306 enters the chuck body 21, the detection rubber ring 307 is fitted onto the outer surface of the detection disc 306, ensuring that the diameter of the detection disc 306 plus the detection rubber ring 307 is consistent with that of the clamping member 309. When the connecting assembly 11 drives the chuck body 21 to rotate, the clamping member 309, held by the chuck body 21's clamping blocks, will rotate along with it. 306 is rotatably connected to the clamping member 309. The second detection disk 306 and the first detection disk 304 will not rotate together with the clamping member 309. When the rotation angle of the chuck body 21 deviates, the clamping block will rub against the second detection rubber ring 307 sleeved on the outer surface of the second detection disk 306 to determine whether the rotation accuracy of the chuck body 21 is qualified. The first detection disk 304 is located on the top of the clamping block of the chuck body 21. When the clamping block is not installed evenly inside the chuck body 21, the clamping block will also rub against the first detection rubber ring 305 to achieve the effect of micro-motion detection of the chuck body 21.

[0032] It should be noted that the chuck body 21 is the indexing chuck. The indexing chuck has a circular structure. Three or more sliding clamping blocks are installed on the top of the chuck. By moving the clamping blocks, workpieces of different specifications are clamped and limited to the top of the indexing chuck and rotated at an angle. The chuck body 21 is existing technology, and its working principle is common knowledge to those skilled in the art, so it will not be described in detail here.

[0033] Considering the issue of how to clamp and fix the chuck body 21 to the top of the placement tray 2, the following is presented: Figure 3 and Figure 5The specific structure of the clamping assembly 22 is disclosed. The clamping assembly 22 includes an arc-shaped plate 201 fixedly installed on the top of the placement tray 2. A connecting block 202 is fixedly installed on the outer surface of the arc-shaped plate 201. A rotating block 203 is hinged inside the connecting block 202. A stop plate 204 is fixedly installed on the top of the rotating block 203. An insertion interface is provided on the top of the stop plate 204. A positioning post 205 is inserted into the insertion interface. A fastening sleeve 206 is threadedly connected to the outer surface of the positioning post 205.

[0034] The top of the placement tray 2 has a positioning hole 4, and the bottom of the positioning post 205 is inserted into the positioning hole 4. Three clamping components 22 are provided, and the three clamping components 22 are arranged in a circumferential array on the outer surface of the chuck body 21, which are used to limit and fix the chuck body 21 to the top of the placement tray 2.

[0035] Through the above technical solution, an arc-shaped plate 201 is installed on the top of the placement tray 2, and a connecting block 202 is fixedly installed on the outer surface of the arc-shaped plate 201, so that the rotating block 203 can be rotatably installed into the interior of the connecting block 202 through the rotating shaft. Then, the abutment plate 204 is fixedly installed on the top of the rotating block 203. The abutment plate 204 can rotate at the top of the arc-shaped plate 201 with the help of the rotating block 203. The positioning post 205 is inserted into the insertion interface opened on the top of the abutment plate 204. The chuck body 21 is placed inside the three arc-shaped plates 201, and the rotating abutment plate 204 abuts against the chuck body 2. The top of the chuck body 21 is inserted into the positioning hole 4, and the bottom of the positioning pin 205 is inserted into the positioning hole 4. Before the positioning pin 205 is inserted into the positioning hole 4, the fastening sleeve 206 needs to be screwed onto the outer surface of the positioning pin 205. After the positioning pin 205 is inserted into the positioning hole 4, the pin cap at the top of the positioning pin 205 is exactly against the top of the abutment plate 204. At this time, the abutment plate 204 is in a horizontal state. The fastening cap is rotated to abut the bottom of the abutment plate 204, so that the abutment plate 204 can limit and fix the top of the chuck body 21, thereby achieving the effect of limiting and fixing the chuck body 21 to the top of the placement plate 2.

[0036] Considering again the question of how to drive the chuck body 21, which is fixed at the top of the placement tray 2, to rotate, the following is presented: Figure 1 and Figure 3 The specific structure of the connecting component 11 is disclosed. The connecting component 11 includes a drive motor 101 installed inside the mounting port and a collar 102 fixedly installed on the top of the detection table 1. A connecting plate 103 is fixedly installed on the top of the collar 102. A rotating interface is provided on the top of the connecting plate 103. A rotating plate 104 is rotatably installed inside the rotating interface. The output shaft of the drive motor 101 passes through the connecting plate 103 and is installed inside the rotating plate 104.

[0037] The rotating disk 104 is fixedly installed at the bottom of the placement disk 2. The rotation of the rotating disk 104 can drive the placement disk 2 to rotate together.

[0038] Through the above technical solution, the drive motor 101 is installed in the fixed position inside the mounting port, the collar 102 is fixedly installed on the top of the placement plate 2, and the collar 102 is sleeved on the outside of the drive motor 101. The connecting plate 103 is fixedly installed on the top of the collar 102, so that the rotating plate 104 can be rotatably installed into the rotating interface opened on the top of the connecting plate 103. The output shaft of the drive motor 101 passes through the connecting plate 103 and is fixedly connected to the bottom of the rotating plate 104. Then, the drive motor 101 starts and drives the rotating plate 104 to rotate, which can drive the placement plate 2 fixedly connected to the top of the rotating plate 104 to rotate together, so as to achieve the effect of rotating the chuck body 21, which is fixedly fixed on the top of the placement plate 2, and making it convenient to clamp and place the chuck body 21 and perform micro-clamping.

[0039] In summary, the working principle of this utility model is as follows:

[0040] When performing micro-motion detection on the chuck body 21, first place the chuck body 21 inside the three arc plates 201, rotate the abutment plate 204 to abut the top of the chuck body 21, and insert the bottom of the positioning pin 205 into the positioning hole 4. Before the positioning pin 205 is inserted into the positioning hole 4, the fastening sleeve 206 needs to be threaded to the outer surface of the positioning pin 205. After the positioning pin 205 is inserted into the positioning hole 4, the pin cap at the top of the positioning pin 205 is exactly against the top of the abutment plate 204. At this time, the abutment plate 204 is in a horizontal state. Rotate the fastening cap to abut the bottom of the abutment plate 204 so that the abutment plate 204 can limit and fix the top of the chuck body 21, thereby achieving the effect of limiting and fixing the chuck body 21 to the top of the placement plate 2.

[0041] Then, the electric push rod 303 is activated to push the detection disc 304 to the top of the clamping block of the chuck body 21. At this time, the detection rubber ring 305 is also at the top of the clamping block of the chuck body 21. The detection disc 306 at the bottom of the detection disc 304 and the clamping member 309 will enter the interior of the clamping block of the chuck body 21. Activating the chuck body 21 can cause the clamping block to clamp the clamping member 309. When the drive motor 101 is energized to drive the chuck body 21 at the top of the placement disc 2 to rotate, the clamping member 309, clamped by the clamping block of the chuck body 21, will rotate together, detecting... The second detection disc 306 is rotatably connected to the clamping member 309. The second detection disc 306 and the first detection disc 304 will not rotate together with the clamping member 309. When the rotation angle of the chuck body 21 deviates, the inner wall of the clamping block will rub against the detection rubber ring 307 sleeved on the outer surface of the second detection disc 306. This indicates that the rotation accuracy of the chuck body 21 is unqualified. The first detection disc 304 is located on the top of the clamping block of the chuck body 21. When the clamping block is not installed on the top of the chuck body 21, the clamping block will also rub against the first detection rubber ring 305, achieving the effect of micro-motion detection of the chuck body 21.
