Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a universal length measuring instrument with a rapid positioning mechanism. Background Technology

[0002] A universal length measuring instrument is a high-precision length measuring instrument widely used in mechanical manufacturing, precision machining, and metrology. It is mainly used to accurately measure the internal and external dimensions, internal and external thread diameters, and internal and external tapers of various precision parts. In the traditional measurement process, the operator needs to place the object to be measured on the worktable of the measuring instrument, and then drive the measuring head or clamping device to move slowly by manually rotating the handwheel or moving the slider until the object to be measured is aligned and clamped. This process is the basis for ensuring the accuracy of subsequent measurement data.

[0003] However, this positioning and clamping method, which relies entirely on manual operation, has obvious shortcomings. First, the process is time-consuming, especially during batch testing, where frequent manual adjustments severely affect the overall measurement efficiency. Second, the accuracy of positioning and the magnitude of clamping force depend entirely on the operator's experience and feel, which can easily introduce human error and lead to a decrease in the consistency and reliability of measurement results.

[0004] Therefore, this utility model proposes a universal length measuring instrument with a rapid positioning mechanism to overcome the shortcomings of the prior art. Summary of the Invention

[0005] In view of the problems of existing universal length measuring instruments, such as reliance on manual operation for positioning and clamping, low efficiency and easy introduction of errors, as well as limited measurement angle and limited applicability, this utility model aims to provide a universal length measuring instrument with a rapid positioning mechanism that has an improved structure and can effectively solve the above problems.

[0006] This utility model provides a universal length measuring instrument with a rapid positioning mechanism, including: a base, a fixed block, a guide rail, a moving block, a clamping plate and a moving measuring seat; as well as a connecting plate, a bottom plate, a motor, a rotating column, a second rotating plate, a second moving column, a first rotating plate and a first moving column.

[0007] The fixed block is fixedly connected to the base, the guide rail is fixedly connected to the fixed block, the moving block is slidably connected to the guide rail, the clamping plate is fixedly connected to the moving block, and the moving measuring seat is fixedly connected to the clamping plate.

[0008] Furthermore, one end of the connecting plate is fixedly connected to the base, the base plate is fixedly connected to the other end of the connecting plate, and the motor is fixedly connected to the base plate. The motor drives the rotating column through a transmission connection. The rotating column, the second rotating plate, the second moving column, the first rotating plate, and the first moving column are connected in sequence by hinges or rotations to form a linkage mechanism. The end of the linkage mechanism, namely the first moving column, is hinged to the moving block, thereby converting the rotational motion of the motor into the linear clamping motion of the moving block.

[0009] Preferably, a limit baffle is also fixedly connected to the base. This limit baffle is configured to limit the movement range of the movable measuring seat and play a protective role.

[0010] Preferably, the universal length measuring instrument also includes an angle adjustment mechanism, which is fixedly connected to the base and adjacent to the movable measuring seat, for adjusting the measuring angle.

[0011] Furthermore, the angle adjustment mechanism includes a slider and a measuring head, with the measuring head rotatably connected to the slider, thereby enabling angle adjustment.

[0012] In one specific implementation, the angle adjustment mechanism also includes a knob and a rotating shaft. The knob is fixedly connected to the outer surface of the measuring head, one end of the rotating shaft is fixedly connected to the measuring head, and the other end of the rotating shaft is rotatably inserted into the slider.

[0013] Furthermore, the slider has a second positioning hole for the rotating shaft to pass through, and the rotating shaft has a first positioning hole on its circumferential surface. The slider also has a third positioning hole, the axis of which intersects perpendicularly with the axis of the second positioning hole.

[0014] Preferably, the angle adjustment mechanism further includes a pin configured to be insertable and removable through both positioning hole one and positioning hole three when the positioning hole one is aligned with positioning hole three, thereby locking the rotating shaft relative to the slider and fixing the angle of the measuring head.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting a linkage mechanism driven by a motor, converts the rotational motion of the motor into the linear motion of the moving block on the guide rail, thereby driving the clamping plate and the moving measuring seat to automatically clamp the object to be measured. This solves the problem that in the prior art, universal length measuring instruments require manual adjustment of the clamping components for positioning before measurement, which is cumbersome, time-consuming, and prone to positioning errors due to human factors. It achieves the technical effect of rapid automatic positioning and clamping, improving measurement efficiency, reducing human operation errors, and enhancing practicality.

[0016] 2. This utility model solves the problems of fixed measuring head angle, limited measuring range, inability to adapt to different angle measurement needs, and difficulty in eliminating angle deviation in the prior art by setting an angle adjustment mechanism consisting of a measuring head, rotating shaft, slider, pin and multiple positioning holes that cooperate with each other. It achieves the technical effect of freely adjusting the measuring angle and reliably locking it, thereby expanding the measuring range, improving the measuring accuracy and applicability of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0020] Please refer to Figures 1 to 4This utility model provides a universal length measuring instrument with a rapid positioning mechanism, including a base 1, which serves as the mounting base for the entire device. A fixing block 10 is fixedly connected to the base 1, a guide rail 12 is fixedly connected to the fixing block 10, a moving block 5 is slidably connected to the guide rail 12, a clamping plate 14 is fixedly connected to the moving block 5, and a moving measuring seat 4 is further fixedly connected to the clamping plate 14. The moving block 5, the clamping plate 14, and the moving measuring seat 4 together constitute a moving unit for clamping and measuring workpieces. In order to realize the automatic driving of the moving unit, a connecting plate 9 is also fixedly connected to the base 1, a base plate 15 is fixedly connected to the connecting plate 9, and a motor 16, which serves as a driving source, is fixedly installed on the base plate 15. The output end of motor 16 is connected to rotating column 8. One end of rotating column 8 is hinged to rotating plate 7. The other end of rotating plate 7 is hinged to one end of moving column 13. The other end of moving column 13 is rotatably connected to rotating plate 6. One end of moving column 11 is hinged to rotating plate 6. The other end of moving column 11 is hinged to moving block 5. Through this series of linkage mechanisms, the rotational motion of motor 16 is converted into linear reciprocating motion of moving block 5 along guide rail 12, thereby driving clamping plate 14 and moving measuring seat 4 to achieve rapid clamping and positioning of the object to be measured.

[0021] To further expand measurement functions and improve measurement accuracy, the universal length gauge with a quick positioning mechanism also includes an angle adjustment mechanism 2 fixedly connected to the base 1 and adjacent to the movable measuring seat 4. Furthermore, a stable installation and functional relationship is formed between the angle adjustment mechanism 2 and the base 1. Please refer to... Figure 3 and Figure 4 The structure is described in detail below: The angle adjustment mechanism 2 includes a slider 205 as a mounting base. The slider 205 has a second positioning hole 206 for the rotating shaft 203 to be rotatably mounted, and a third positioning hole 207 for locking the angle. The axis of the third positioning hole 207 intersects perpendicularly with the axis of the second positioning hole 206. The angle adjustment mechanism 2 also includes a measuring head 202 fixedly connected to the knob 201. One end of a rotating shaft 203 is fixedly connected to the bottom of the measuring head 202. A positioning hole 204 is provided on the circumferential surface of the rotating shaft 203. In the assembled state, the other end of the rotating shaft 203 is rotatably inserted and accommodated in the positioning hole 206 of the slider 205. This rotational engagement allows the measuring head 202 to rotate freely around the central axis of the rotating shaft 203. To achieve precise angle fixing, the angle adjustment mechanism 2 also includes a pin 208. When the knob 201 is rotated to drive the measuring head 202 to a predetermined angle, the positioning hole 204 on the rotating shaft 203 and the positioning hole 207 on the slider 205 are aligned. At this time, the pin 208 can be inserted and removed simultaneously through the positioning hole 207 and the positioning hole 204. Through the limiting effect of the pin 208, the circumferential locking of the rotating shaft 203 relative to the slider 205 is achieved, thereby ensuring the angle stability and high precision of the measuring head 202 during the measurement process.

[0022] As a preferred embodiment, in order to effectively protect and limit the travel distance of the movable measuring base 4, please refer to... Figure 1 A limit baffle 3 is also fixedly connected to the base 1. The position of the limit baffle 3 is close to the end of the movement path of the moving measuring seat 4. When the moving measuring seat 4 moves to the limit position, it will contact the limit baffle 3, thereby preventing damage to the transmission mechanism or measuring unit due to excessive movement.

[0023] Working principle: First, the object to be measured is placed in the center of the top surface of the base 1. The motor 16 is started. The base plate 15 provides a fixed installation position for the motor 16, the connecting plate 9 provides a fixed installation position for the base plate 15, and the base 1 provides a fixed installation position for the connecting plate 9. The motor 16 drives the rotating column 8 to rotate, the rotating column 8 drives the rotating plate 7 to move, the rotating plate 7 drives the moving column 13 to move, the moving column 13 drives the rotating plate 6 to move and rotate around the moving column 13, the rotating plate 6 drives the moving column 11 to move, the moving column 11 drives the moving block 5 to move, and the moving block 5... Sliding on the guide rail 12, the guide rail 12 restricts movement to only horizontal. The fixed block 10 provides a fixed installation position for the guide rail 12. The moving block 5 drives the clamping plate 14 to move towards the center, so that the moving block 5 and the fixed measuring seat on the right clamp and fix the object to be measured. At the same time, the clamping plate 14 drives the moving measuring seat 4 to move to the right. The limit baffle 3 restricts the movement range of the moving measuring seat 4. The object can be measured at the same time it is clamped, thus achieving the function of quickly positioning the length measuring machine, improving measurement efficiency, reducing waiting time, reducing human operation error, and improving practicality. First, pull the pin 208 out of the positioning hole 204 in the angle adjustment mechanism 2, and turn the knob 201. The knob 201 drives the measuring head 202 to rotate, and the measuring head 202 drives the rotating shaft 203 to rotate. The rotating shaft 203 rotates in the positioning hole 206. The slider 205 provides a fixed position for the positioning hole 206. When the angle is appropriate, insert the pin 208 into both the positioning hole 307 and the positioning hole 204 to fix the measuring head 202. This achieves the function of adjusting the angle of the measuring unit, expanding the measurement range, eliminating angle deviation, improving measurement accuracy, and enhancing practicality.
