Description

Technical Field

[0001] This utility model relates to the field of measurement technology, specifically to a surface roughness profile shape measuring device. Background Technology

[0002] In modern manufacturing, surface roughness and profile measuring machines play a crucial role in ensuring product quality. Accurate measurement of the surface roughness and profile of a workpiece effectively controls product performance, reliability, and lifespan. However, the accuracy and efficiency of the measurement largely depend on the clamping fixture used.

[0003] Existing clamping fixtures for surface roughness profile measuring machines have several limitations. Firstly, they limit the types of workpieces they can clamp. Different workpieces have varying shapes, sizes, and material properties, such as cylindrical, plate, and irregularly shaped workpieces. Traditional clamping fixtures are often designed for workpieces with specific shapes or size ranges; for example, some fixtures designed specifically for cylindrical workpieces are unsuitable for plate-shaped or irregularly shaped workpieces. This necessitates frequent changes of clamping fixtures when measuring different types of workpieces, which not only consumes significant time and manpower but also increases the risk of measurement errors due to improper operation during fixture changes.

[0004] On the other hand, existing clamping fixtures lack flexibility in adjustment. For situations requiring precise adjustment of workpiece position and angle to meet measurement requirements, traditional fixtures struggle to achieve quick and accurate adjustments. For example, when measuring workpieces with inclined surfaces or complex contours, the fixture cannot easily adjust the workpiece to a suitable measurement posture, thus affecting the accuracy and completeness of the measurement results.

[0005] Furthermore, the deficiencies in the versatility and compatibility of existing tooling restrict its application in diverse production environments. With the rapid development of the manufacturing industry and frequent product updates, enterprises need tooling equipment capable of adapting to various workpiece measurement needs. However, existing tooling cannot meet this trend, severely impacting production efficiency and quality control. Therefore, there is an urgent practical need to develop a clamping tooling for surface roughness profile shape measuring machines that can overcome the aforementioned deficiencies and possess broad applicability and flexible adjustment capabilities. Utility Model Content

[0006] To address the aforementioned problems, this invention provides a surface roughness profile shape measuring device.

[0007] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0008] A surface roughness profile measuring device includes a support base. Slide grooves are formed on the inner walls of both the front and rear sides of the support base. A cylinder is provided on the outer walls of both the front and rear sides of the support base. The inner drive end of the cylinder extends into the support base and is provided with a clamping plate. A second cylinder is provided on the inner bottom wall of the support base. A support plate is provided on the top drive end wall of the second cylinder. Slider blocks are provided on both the front and rear sides of the outer wall of the support plate and are slidably connected to the slide grooves. Lateral clamping mechanisms are provided on the bottom ends of both the left and right sides of the outer wall of the support base.

[0009] Furthermore, the transverse clamping mechanism includes a base, a motor is provided on the outer side of the inner bottom wall of the base, the output end of the motor is locked with a lead screw through a coupling, and the other end of the lead screw is rotatably connected to the inner wall of the base through a bearing. A connecting block is threadedly connected to the outer wall of the lead screw, a connecting rod is provided on the top wall of the connecting block, and a clamping plate is provided on the inner end wall between the connecting rods through a connecting seat.

[0010] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the base through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0011] Furthermore, an elongated hole is provided on the upper surface of the base.

[0012] Furthermore, the inner end walls of the second clamping plate and the first clamping plate are provided with elastic anti-slip pads.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through its unique structural design, greatly expands the types of workpieces that the tooling can clamp. The support plate can flexibly adjust its support height under the drive of cylinder two, adapting to plate workpieces of different thicknesses, as well as cylindrical and irregularly shaped workpieces of varying heights. There is no need to change the tooling due to changes in workpiece thickness. Clamping plate one can be independently adjusted in clamping position under the action of cylinder one, and clamping plate two can be driven by motors and lead screws. Whether it is a cylindrical workpiece or an irregularly shaped workpiece, a suitable clamping point can be found for stable fixation. This effectively solves the problem that traditional tooling can only be adapted to workpieces of specific shapes, greatly improving the versatility of the tooling in diverse production environments.

[0015] This fixture can quickly adjust the support height of the support plate and the clamping positions of clamping plates one and two according to the actual shape and size of the workpiece, eliminating the need for frequent changes of different types of fixtures as with traditional fixtures. This not only significantly saves time and labor costs associated with changing fixtures, but also avoids operational errors caused by frequent fixture changes, reducing the introduction of measurement errors. The elastic anti-slip pads installed on the inner walls of clamping plates one and two further enhance stability when clamping irregularly shaped workpieces, ensuring that the workpiece will not shift during the measurement process, thereby significantly improving the accuracy and efficiency of the measurement, and effectively enhancing the company's production efficiency and quality control level.

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.

[0023] See Figure 1-3As shown, a surface roughness profile shape measuring device includes a support base 1. The inner walls of the front and rear sides of the support base 1 are provided with sliding grooves 2. The outer walls of the front and rear sides of the support base 1 are provided with cylinders 3. The inner driving end of cylinder 3 extends into the support base 1 and is provided with clamping plate 4. The bottom inner wall of the support base 1 is provided with cylinder 5.

[0024] Furthermore, the transverse clamping mechanism includes a base 8, on the outer side of the inner bottom wall of the base 8, a motor 9 is provided, the output end of the motor 9 is locked with a lead screw 10 through a coupling, and the other end of the lead screw 10 is rotatably connected to the inner wall of the base 8 through a bearing, a connecting block 11 is threadedly connected to the outer wall of the lead screw 10, a connecting rod 12 is provided on the top wall of the connecting block 11, and a clamping plate 14 is provided on the inner end wall between the connecting rods 12 through a connecting seat 13. When the motor 9 is started, the lead screw 10 is rotated, and the lead screw 10 causes the connecting block 11 to drive the connecting rod 12, the connecting seat 13 and the clamping plate 14 to move inward or outward. The two clamping plates 14 are equipped with two driving devices, which can adjust the clamping position of each clamping plate 14 individually.

[0025] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the base 8 through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw 10. The bearing fixes the lead screw 10, making it easier for the lead screw 10 to rotate through the bearing.

[0026] Furthermore, an elongated hole is provided on the upper surface of the base 8 for the connecting rod 12 to move.

[0027] Furthermore, the inner end walls of clamping plate 2 14 and clamping plate 1 4 are provided with elastic anti-slip pads, which can improve the stability of clamping irregularly shaped workpieces.

[0028] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0029] One specific application of this embodiment is:

[0030] In practical use, this clamping fixture demonstrates excellent convenience and flexibility. When dealing with different types of workpieces, firstly, cylinder 25 is activated. After cylinder 25 is working, it generates a linear driving force. This driving force causes the support plate 6 to move smoothly up or down on the connected slider 7 on the specific guide rail groove 2. Through this operation, the support height of the support plate 6 can be precisely adjusted very easily. This adjustment method can easily handle plate workpieces of different thicknesses, whether it is a thin plate as thin as paper or a thicker block plate, a suitable support height can be found. For cylindrical workpieces of varying heights and irregularly shaped workpieces with complex shapes, this adjustment function can also ensure that the bottom of the workpiece is in a suitable support position, without having to change different fixtures due to differences in workpiece thickness, which greatly improves the versatility of the fixture.

[0031] The clamping plate 4 in the tooling is driven by two independent cylinders 3, enabling flexible position adjustment. When cylinder 3 is activated, the force output by cylinder 3 pushes clamping plate 4, allowing it to move precisely along a predetermined track inward or outward. Since each clamping plate 4 is equipped with an individual cylinder 3, the operator can finely adjust the clamping position of each clamping plate 4 according to the specific shape and size of the workpiece. For example, when clamping irregularly shaped workpieces, the position of the two clamping plates 4 can be flexibly controlled according to the protruding or recessed parts of the workpiece to find the optimal clamping point, thereby achieving a stable fixation of the workpiece.

[0032] As a key component driving the second clamping plate 14, the motor 9 will run at high speed after startup, driving the lead screw 10 connected to it to rotate synchronously. The rotational motion of the lead screw 10 has unique transmission characteristics, which can convert the rotational power output by the motor 9 into linear motion. During the rotation of the lead screw 10, the connecting block 11, which is threaded with the lead screw 10, will be pushed by the thread of the lead screw 10, and then move linearly along the axial direction of the lead screw 10. The movement of the connecting block 11 will drive the connecting rod 12, the connecting seat 13, and the second clamping plate 14 connected to it to move synchronously inward or outward. Similar to the first clamping plate 4, the two second clamping plates 14 are also equipped with two independent drive devices (i.e., the drive system composed of the motor 9 and the lead screw 10, etc.). The operator can make precise adjustments to the clamping position of each second clamping plate 14 according to the actual measurement needs. This independent adjustment design enables the tooling to clamp and position workpieces of various complex shapes from all directions and multiple angles, further enhancing the applicability of the tooling.

[0033] Before clamping and fixing the workpiece, the operator needs to comprehensively adjust the support height of the support plate 6 and the clamping positions of clamping plate 4 and clamping plate 14 according to the actual shape and size of the workpiece. It is worth mentioning that the inner walls of clamping plate 4 and clamping plate 14 are equipped with elastic anti-slip pads. These anti-slip pads are made of special rubber or silicone material, which has good flexibility and friction. When clamping irregularly shaped workpieces, the anti-slip pads can adaptively deform according to the undulation shape of the workpiece surface and fit tightly against the workpiece surface. This not only effectively prevents the workpiece from sliding during the clamping process, but also further enhances the clamping stability of the workpiece, ensuring that the workpiece remains in a fixed position throughout the measurement process, and providing a reliable guarantee for the measuring machine to accurately obtain the surface roughness and contour shape data of the workpiece.

[0034] After completing the above adjustments and preparations, place the workpiece to be measured smoothly on the support plate 6. At this time, start cylinder 3 and motor 9 again. Cylinder 3 drives clamping plate 4 and motor 9 drives clamping plate 14 to move inward at the same time, gradually approaching the workpiece. As clamping plate 4 and clamping plate 14 move closer, they will clamp the workpiece from different directions until the workpiece is firmly fixed on the fixture, completing the clamping and fixing operation of the entire workpiece, and making full preparations for the subsequent surface roughness profile shape measurement work.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
