Abstract
Description
Technical Field
[0001] This utility model belongs to the field of camshaft processing technology, specifically referring to a measuring device for camshaft pretreatment. Background Technology
[0002] In the manufacturing process of camshafts, measurement during the pretreatment stage is a crucial step in ensuring the accuracy of subsequent machining. However, existing camshaft measuring devices have the following problems:
[0003] 1. The clamping and positioning accuracy of the camshaft is low, often requiring multiple adjustments to achieve accurate measurement. This is cumbersome and prone to large measurement errors due to inaccurate positioning.
[0004] 2. The device has poor versatility. Different measuring fixtures need to be changed for camshafts of different specifications and lengths, which increases production costs and operation time. Utility Model Content
[0005] The technical problem to be solved by this utility model is the low clamping and positioning accuracy and poor versatility of existing camshaft measuring devices.
[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: A measuring device for camshaft pretreatment includes two sets of housings and baffles arranged opposite to each other. A rectangular telescopic rod and a circular telescopic rod are respectively fixed between the two sets of housings and the two sets of baffles. An upper V-shaped clamp and a lower V-shaped clamp are slidably arranged between the housings and the baffles. A driving component for driving the upper V-shaped clamp and the lower V-shaped clamp to move relative to each other is provided on the housing. A measuring component is provided on the baffle.
[0007] Furthermore, the drive assembly includes a connecting block one and a connecting block two, which are respectively fixedly connected to the two ends of the upper V-clamp and the lower V-clamp. A sliding groove is provided on the side wall of the housing for the connecting block two to slide. A T-shaped lead screw is rotatably provided at the upper end of the housing, and the lower end of the T-shaped lead screw extends into the housing and is rotatably connected to the bottom wall of the housing.
[0008] Furthermore, the T-shaped lead screw is threadedly connected to two connecting blocks, and the internal threads of the two connecting blocks rotate in opposite directions.
[0009] Furthermore, the measuring component includes a laser rangefinder fixedly mounted on the side wall of the baffle plate, and the laser rangefinder is connected to the back-end system. A circular cutout is fixedly opened on the baffle plate, and a transmitter located inside the circular cutout is fixedly mounted on the laser rangefinder.
[0010] Furthermore, the output direction of the transmitter is on the same horizontal plane as the center point of the upper V-clamp and the lower V-clamp.
[0011] Furthermore, the opposing surfaces of the upper V-shaped clamp and the lower V-shaped clamp are both provided with a rubber coating.
[0012] The beneficial effects of this utility model by adopting the above structure are as follows:
[0013] 1. The drive assembly drives the two connecting blocks to move relative to each other via a T-shaped lead screw, thereby achieving relative movement between the upper and lower V-clamps. This securely clamps the camshaft. Furthermore, because the internal threads of the two connecting blocks rotate in opposite directions, the movement of the upper and lower V-clamps is more synchronized and precise. Simultaneously, after clamping, the camshaft axis and the laser rangefinder are on the same horizontal line. Activating the laser rangefinder completes the measurement, greatly improving measurement efficiency and accuracy.
[0014] 2. The use of rectangular and circular telescopic rods allows for flexible adjustment of the distance between the two sets of housings and the grid plates, enabling the measurement of camshafts of different lengths and specifications, thus increasing the versatility of the device. Furthermore, multiple sets of measuring components can be installed on the device according to actual measurement needs, meeting diverse measurement requirements. Attached Figure Description

[0021] 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.
[0022] Example 1:
[0023] like Figure 1-4 As shown, a measuring device for camshaft pretreatment includes two sets of housings 1 and baffles 2 arranged opposite to each other. A rectangular telescopic rod 3 and a circular telescopic rod 4 are fixedly arranged between the two sets of housings 1 and the two sets of baffles 2, respectively. An upper V-clamp 5 and a lower V-clamp 6 are slidably arranged between the housings 1 and the baffles 2. A driving component is provided on the housings 1 and a measuring component is provided on the baffles 2.
[0024] like Figure 1-4 As shown, the drive assembly includes a first connecting block 8 and a second connecting block 9, which are respectively fixedly connected to the two ends of the upper V-clamp 5 and the lower V-clamp 6. A sliding groove is provided on the side wall of the housing 1 for the second connecting block 9 to slide. A T-shaped lead screw 10 is rotatably provided on the upper end of the housing 1. The lower end of the T-shaped lead screw 10 extends into the interior of the housing 1 and is rotatably connected to the bottom wall of the housing 1. The T-shaped lead screw 10 is threadedly connected to the two second connecting blocks 9, and the internal threads of the two second connecting blocks 9 rotate in opposite directions.
[0025] like Figure 1-4 As shown, the measuring assembly includes a laser rangefinder 7 fixedly mounted on the side wall of the baffle plate 2. The laser rangefinder 7 is connected to the back-end system. A circular cutout is fixedly opened on the baffle plate 2. An emitter 11 is fixedly mounted on the laser rangefinder 7 within the circular cutout. The output direction of the emitter 11 is on the same horizontal plane as the center points of the upper V-clamp 5 and the lower V-clamp 6. The opposing surfaces of the upper V-clamp 5 and the lower V-clamp 6 are coated with rubber to protect the camshaft from damage. During use, the laser rangefinder 7 needs to be activated for benchmark testing. Then, according to the specifications of the camshaft to be measured, the rectangular telescopic rod 3 and... The length of the circular telescopic rod ensures that the overall size of the device matches the camshaft. The camshaft is placed between the upper V-clamp 5 and the lower V-clamp 6. The T-screw 10 is turned. Since the T-screw 10 is threadedly connected to the two connecting blocks 9 with opposite thread directions, the two connecting blocks 9 drive the upper V-clamp 5 and the lower V-clamp 6 to move relative to each other, gradually approaching and clamping the camshaft. After clamping, the axis of the camshaft is on the same horizontal line as the laser rangefinder 7. The laser rangefinder 7 is activated, and the transmitter 11 emits a laser to measure the camshaft. The measurement data is transmitted to the back-end system for processing and analysis.
[0026] Example 2:
[0027] Based on Example 1, such as Figure 1-4 As shown, multiple sets of housings 1, baffles 2, and corresponding upper V-clamps 5, lower V-clamps 6, and measuring components can be added to the rectangular telescopic rod 3 and the circular telescopic rod 4 according to measurement requirements, so as to realize simultaneous measurement of multiple positions of the camshaft and improve measurement efficiency.
