Description

Technical Field

[0001] This utility model relates to the field of caliper technology, specifically a new type of caliper for measuring mechanical processing. Background Technology

[0002] In the field of machining, it is often necessary to measure machinery. As one of the most basic measuring tools, the technological evolution of calipers has always revolved around improving accuracy, expanding functions, making it easier to operate and adapting to the environment.

[0003] CN213147595U discloses a measuring tool for machining, belonging to the field of machining. The measuring tool includes a caliper body and a sliding measuring frame slidably connected to the caliper body. It further includes: an outer diameter measuring scale connected to the sliding measuring frame; a clamping plate slidably connected inside the outer diameter measuring scale and in contact with the caliper body; a drive slider slidably connected inside the outer diameter measuring scale; wherein a sliding plate is fixedly connected to the drive slider, and a wedge-shaped plate is provided on the clamping plate in contact with the sliding plate; a return spring, with both ends fixedly connected to the drive slider and the outer diameter measuring scale respectively; an elastic rope; and a locking device for locking the clamping plate after it slides. This device, by setting a clamping plate driven by a drive slider, can automatically lock after clamping with the workpiece, improving clamping stability and measurement accuracy, and increasing detection efficiency.

[0004] When the clamping plate slides, the device can limit the clamping plate under the action of the locking plate, locking spring, locking block, and locking groove to prevent the clamping plate from resetting, thereby improving the clamping effect between the rubber block and the caliper body. However, the device is relatively troublesome to use, requiring manual movement of the clamping plate to the appropriate position before locking. It is slow to measure and is prone to errors during measurement.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing structure of new calipers used for machining and measurement. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of caliper for machining measurement, in order to solve the problems mentioned in the background art, which are that the device is cumbersome to use, requiring manual movement of the clamping plate to the appropriate position before locking, resulting in slow measurement efficiency and easy errors during measurement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel caliper for measuring machining, comprising a main scale, a side baffle, a first measuring jaw, a vernier scale, and a second measuring jaw. The side baffle is fixedly connected to the outside of the main scale, and the first measuring jaw is fixedly connected to the bottom of the main scale. The vernier scale is slidably connected to the outside of the main scale, and the second measuring jaw is fixedly connected to the bottom of the vernier scale. The second measuring jaw and the first measuring jaw are distributed in a left-right correspondence.

[0008] Preferably, the bottoms of the first measuring claw and the second measuring claw are inverted conical structures; this structure allows the first measuring claw and the second measuring claw to better engage and fix the workpiece on both sides.

[0009] Preferably, a first guide rod is slidably connected to the inner side of the side baffle, and a push plate is fixedly connected to the outer side of the first guide rod, and a first telescopic spring is connected between the push plate and the side baffle; this structure allows the push plate to be reset by the first telescopic spring through its own elastic force.

[0010] Preferably, a connecting block is fixedly connected to the top of the vernier scale, and the connecting block is connected to the push plate by a traction rope; this structure allows the connecting block and the push plate to be connected by a traction rope, which can generate a traction force on the connecting block, thereby causing the vernier scale to slide left and right along the outside of the main scale.

[0011] Preferably, a guide wheel assembly is installed on the outer side of the side baffle and the outer side of the main scale, and a traction rope is wound around the outer side of the guide wheel assembly; in this structure, the guide wheel assembly installed on the outer side of the side baffle and the outer side of the main scale can guide the traction force of the traction rope through the guide wheel assembly, so that it can pull the vernier scale to slide on the outer side of the main scale.

[0012] Preferably, a second guide rod is fixedly connected to the outer side of the side baffle, and a connecting block is slidably connected to the outer side of the second guide rod; in this structure, the second guide rod fixedly connected to the outer side of the side baffle can guide the movement direction of the vernier scale through the second guide rod, thereby improving the accuracy of the vernier scale's movement position.

[0013] Preferably, a second telescopic spring is connected between the connecting block and the side baffle; in this structure, the second telescopic spring connecting the connecting block and the side baffle can cause the vernier caliper to reset automatically through the elastic force of the second telescopic spring.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the novel caliper for machining measurement is equipped with:

[0015] 1. Convenient measuring structure: When measuring mechanical parts, the first and second measuring jaws are placed on both sides of the workpiece. Then, the side baffle is held and the push plate is pushed forward with the palm of the hand. The push plate compresses the first telescopic spring and moves towards the side baffle, simultaneously driving the traction rope. The traction rope is guided by the guide wheel assembly to generate traction force on the vernier scale, causing it to slide along the outside of the main scale. This makes the first and second measuring jaws contact both sides of the workpiece for measurement. Compared with calipers on the market, this device is highly efficient and convenient, and can quickly measure a large number of workpieces.

[0016] 2. Reset Structure: After the workpiece measurement is completed, the push plate is released, and the push plate will reset due to the elasticity of the first telescopic spring. After the push plate resets, the traction rope is in a slack state, and the vernier caliper loses the traction force of the traction rope. It will reset due to the elasticity of the second telescopic spring, thereby moving the vernier caliper towards the rear of the main scale, separating the first and second measuring jaws, which facilitates subsequent measurement operations. Compared with calipers on the market, there is no need for manual separation, which can improve measurement efficiency. Attached Figure Description

[0027] When this structure is used to measure mechanical parts, the first measuring jaw 3 and the second measuring jaw 5 are first placed on both sides of the workpiece. Then, the side baffle 2 is held and the push plate 7 is pushed forward with the palm of the hand. The push plate 7 compresses the first telescopic spring 8 and moves towards the side baffle 2, and simultaneously drives the traction rope 9. The traction rope 9 is guided by the guide wheel group 11 to generate traction force on the vernier scale 4, so that it slides along the outside of the main scale 1, so that the first measuring jaw 3 and the second measuring jaw 5 abut against both sides of the workpiece to measure the workpiece.
