Compare in the mode that manual mode detected and adjusted the survey needle, adopt positioning jig 100 can replace manual mode in the embodiment of this application to can improve installation, positioning accuracy, and improve installation and regulation efficiency.
Referring to fig. 2, in some embodiments, the first positioning assembly 120 may further include a rotating seat 122, and the rotating seat 122 may be rotatably disposed at one side of the base 110 for mounting the first positioning member 121. In order to prevent the rotating seat 122 from blocking the through hole 111 and interfering with the probe mounting assembly 200 penetrating into the through hole 111, the rotating seat 122 may be provided with a passage 1221, the passage 1221 of which is coaxial with the through hole 111, so that the probe mounting assembly 200 may pass through the passage 1221 and the through hole 111 to prevent interference with the probe mounting assembly 200. For example, the rotating base 122 may be a rotating ring which is rotatably coupled to the base 110 so as to adjust the position of the first positioning member 121 to be coupled with the first positioning portion 211 of the measuring head 210.
To prevent the pivoting seat 122 from being separated from the base 110, the side wall of the base 110 may be provided with a locking hole 112, as shown in fig. 3, the locking hole 112 being communicated with the through-hole 111, and accordingly, the locking hole 112 is equipped with a locking member 160, e.g., a plunger, a lever, etc., and an end of the locking member 160 extends into the through-hole 111 through the locking hole 112. At least part of the rotating seat 122 penetrates into the through hole 111, and the locking hole 112 is opposite to the part of the rotating seat 122 penetrating into the through hole 111, so that the locking member 160 can prop against the part of the rotating seat 122 penetrating into the through hole 111 to play a role in locking and limiting, and lock the rotating seat 122, and prevent the rotating seat 122 from rotating, shifting in the through hole 111 or being pulled out of the through hole 111 to be separated from the base 110.
Illustratively, the side wall of the rotary seat 122 may be provided with a locking groove, and the end of the locking member 160 extending into the through hole 111 may be engaged with the locking groove, so that the locking function may be improved, and the rotary seat 122 may be effectively prevented from being separated from the base 110. In addition, the locking member 160 may be provided with external threads, and the locking hole 112 may be a threaded hole, so that the locking member 160 and the locking hole 112 may be threadedly engaged with each other.
Based on the above arrangement, after the rotating base 122 rotates to the proper position, in order to prevent the rotating base 122 from rotating, moving or being pulled out of the through hole 111, the portion of the rotating base 122 located in the through hole 111 can be compressed through the locking member 160, so as to achieve a locking effect, so as to prevent the rotating base 122 from rotating, moving or being pulled out of the through hole 111, further, the first positioning member 121 mounted on the rotating base 122 can be effectively prevented from moving, so that the limitation on the measuring head 210 can be achieved through the cooperation of the first positioning member 121 and the first positioning portion 211, and it is ensured that the measuring head 210 does not move.
In order that the first positioning member 121 may move toward the center of the through hole 111 to be engaged with the first positioning portion 211 of the gauge head 210, the side wall of the rotating base 122 may be provided with a first mounting hole 1222, and the first positioning member 121 may be movably inserted through the first mounting hole 1222 such that the first positioning member 121 may move toward the center of the through hole 111 along the first mounting hole 1222.
For example, the first mounting hole 1222 may be a threaded hole, and accordingly, the sidewall of the first positioning member 121 may be provided with an external thread matching the threaded hole, so that the first positioning member 121 may be moved toward the first positioning portion 211 of the measuring head 210 by screwing the first positioning member 121 to achieve matching. Of course, the first mounting hole 1222 may be a conventional hole (i.e., without internal threads), in which case the first positioning member 121 may be directly pushed to move the first positioning member 121 toward the first positioning portion 211 of the probe 210 for engagement.
In some embodiments, the first positioning element 121 may be a first locking pin, and the first positioning portion 211 may be a first positioning hole, so that in the first state, an end of the first locking pin is inserted into the first positioning hole, thereby positioning the measuring head 210 to ensure the position accuracy of the measuring head 210; in the second state, the end of the first lock pin is separated from the first positioning hole, so that the measuring pin mounting assembly 200 after the subsequent positioning is completed can be taken out from the through hole 111. Here, the first state is a state in which the first positioning member 121 and the first positioning portion 211 are engaged, and the second state is a state in which the first positioning member 121 and the first positioning portion 211 are disengaged.
Referring to fig. 3, in some embodiments, the second positioning assembly 130 may include a fixing seat 132, and the fixing seat 132 is connected to a side of the base 110 facing away from the first positioning assembly 120 for installing the second positioning member 131. Specifically, the fixing seat 132 and the rotating seat 122 are respectively located on two opposite sides of the base 110, so that the first positioning element 121 and the second positioning element 131 can be respectively installed.
In order to prevent the fixing seat 132 from blocking the through hole 111 and interfering with the probe mounting assembly 200 passing through the through hole 111, the fixing seat 132 may be disposed around the through hole 111 to prevent interference with the probe mounting assembly 200.
In order to enable the second positioning element 131 to move towards the center of the through hole 111 and to be matched with the second positioning portion 221 of the mounting block 220, the fixing seat 132 is provided with a second mounting hole 1321, and the second positioning element 131 is movably arranged through the second mounting hole 1321, so that the second positioning element 131 can move towards the center of the through hole 111 along the second mounting hole 1321.
For example, the second mounting hole 1321 may be a threaded hole, and accordingly, the sidewall of the second positioning element 131 may be provided with an external thread matching the threaded hole, so that the second positioning element 131 may move toward the second positioning portion 221 of the measuring head 210 to realize matching by screwing the second positioning element 131. Of course, the second mounting hole 1321 may also be a common hole (i.e., without an internal thread), in which case, the second positioning element 131 may be directly pushed to move the second positioning element 131 toward the second positioning portion 221 of the measuring head 210 for fitting.
In some embodiments, the second positioning element 131 may be a second lock pin, and the second positioning portion 221 may be a second positioning hole, so that in the first state, an end portion of the second lock pin penetrates through the second positioning hole, thereby positioning the mounting block 220 to ensure the position accuracy of the mounting block 220; in the second state, the end of the second lock pin is separated from the second positioning hole, so that the probe mounting assembly 200 after the subsequent positioning is completed can be taken out from the through hole 111. It should be noted that the first state is a state in which the second positioning element 131 and the second positioning portion 221 are engaged, and the second state is a state in which the second positioning element 131 and the second positioning portion 221 are disengaged from each other.

Based on this, the caliper body 141 can be moved to make the jaws 1412 engage with the stylus 210, so that the stylus 210 is restricted by the caliper body 141, and at this time, the main body of the measuring apparatus can be moved to separate the stylus 210, thereby enabling the stylus mounting block 200 and the main body of the measuring apparatus to be separated. Of course, in the process of the probe mounting assembly 200 penetrating the through hole 111, in order to prevent the caliper assembly 140 from interfering the movement of the probe mounting assembly 200, the caliper body 141 can be moved to a position away from the through hole 111, so as to avoid shielding the through hole 111, and ensure that the probe mounting assembly 200 can smoothly penetrate the through hole 111.
For example, the sliding portion 1411 may be a slider, and accordingly, the surface of the base 110 may be provided with a sliding groove extending in the radial direction, and the slider is slidably engaged with the sliding groove, so that the caliper body 141 can move in the radial direction of the base 110 to move the jaws 1412 closer to or farther from the measuring head 210. In addition, the clamping jaw 1412 may include two clamping jaw heads arranged at intervals, a clamping space is formed between the two clamping jaw heads, correspondingly, the side wall of the measuring head 210 may be provided with a clamping groove 212, when clamping, the measuring head 210 is accommodated in the clamping space, and the two clamping jaw heads are respectively located in the clamping groove 212, so as to achieve the clamping effect.

Compared with the above manner, in this manner, the slide seat 142 with the slide groove 1421 is additionally added, and the slide portion 1411 is slidably connected to the slide groove 1421, so that the slide groove 1421 can ensure stable movement of the caliper body 141, and limit the moving direction of the caliper body 141, so as to ensure the moving precision of the caliper body 141, and at the same time, the base 110 does not need to be processed, and the overall strength of the base 110 can be ensured to a certain extent. In addition, the sliding base 142 can also rotate synchronously with the rotating base 122 to adjust the orientation of the caliper body 141.
With reference to fig. 2, in order to prevent the caliper body 141 from moving freely, the caliper assembly 140 may further include a limiting member 143, the limiting member 143 is provided with an external thread, correspondingly, the sliding portion 1411 is provided with a threaded hole, the limiting member 143 is engaged with the threaded hole through the external thread, and an end cap of the limiting member 143 can abut against or separate from a groove bottom of the sliding groove 1421. Through the arrangement, the end of the limiting part 143 can be tightly abutted against the bottom of the sliding groove 1421 by screwing the limiting part, and the caliper body 141 can be effectively prevented from moving along the sliding groove 1421 under the action of friction force, so that the stability of the caliper body 141 in clamping connection with the measuring head 210 can be ensured; when the caliper body 141 needs to be moved, the limiting member 143 is unscrewed to separate the end portion from the bottom of the sliding groove 1421, and the locking effect on the sliding portion 1411 is released, and at this time, the caliper body 141 can freely move along the sliding groove 1421, so that the caliper body 141 is separated from the measuring head 210.
In other embodiments, the caliper assembly 140 may further include a lever fixed to the sliding portion 1411, such that the lever can move the entire caliper body 141 to adjust the position of the caliper body 141 by applying a force to the lever.
It should be noted that the shift lever and the stopper 143 may be two separate members, and both are disposed on the sliding portion 1411; of course, the shift lever and the position-limiting element 143 may also be the same component, that is, when the end of the position-limiting element 143 is separated from the bottom of the sliding slot 1421, the position-limiting element 143 may be used as the shift lever, so as to adjust the position of the caliper body 141.
In order to prevent the caliper body 141 from separating from the slide seat 142, a blocking member 144 is further disposed at an outer end of the sliding slot 1421, and the sliding portion 1411 can be blocked by the blocking member 144 to prevent the sliding portion 1411 from sliding out of the sliding slot 1421, thereby ensuring that the caliper body 141 cannot separate from the slide seat 142.
