Description

Technical Field

[0001] This utility model relates to the field of precision measurement technology, and in particular to a high-precision vertical measurement work plate based on a horizontal base support. Background Technology

[0002] In the fields of machining and precision manufacturing, measuring the geometric accuracy of workpieces, especially geometric tolerances such as perpendicularity and flatness, is a key link in ensuring product quality. High-precision vertical measuring worktables based on horizontal base support serve as an important inspection reference device. Their core function is to provide a stable horizontal reference surface and a measurement reference surface that is strictly perpendicular to it, for mounting and positioning the workpiece to be measured, so that it can be accurately measured using measuring tools such as height gauges and dial indicators.

[0003] However, existing measuring work plates still have significant shortcomings in workpiece installation and positioning. The devices generally lack effective auxiliary support structures. During the process of fixing the workpiece to the vertical plate, they cannot provide reliable initial positioning, bottom support, and anti-tipping protection for the workpiece. This not only leads to cumbersome and inefficient clamping operations, but also causes the workpiece to undergo slight deformation or positional shift during the tightening process due to uneven force or direct contact with rigid components. Ultimately, this affects the accuracy of the measurement results and makes it difficult to truly reflect the actual machining precision of the workpiece.

[0004] Therefore, it is necessary to design a high-precision vertical measurement worktable based on a horizontal base support to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing measuring work plates, which lack effective auxiliary support, resulting in inaccurate positioning and easy deformation of workpieces during clamping, thus affecting measurement accuracy, this utility model provides a high-precision vertical measuring work plate based on a horizontal base support.

[0006] Technical solution: A high-precision vertical measurement work plate based on a horizontal base support includes a base plate, a connecting and fixing plate, a vertical plate, a first support plate, a first slider, a support block, and a first soft pad. A vertical plate is fixedly connected to the top of the base plate through connecting and fixing plates symmetrically arranged on the left and right sides. Multiple mounting holes are evenly opened on the front and rear side walls of the vertical plate and the top surface of the base plate. A first support plate is fixedly connected to the lower front side wall of the vertical plate through multiple mounting holes symmetrically arranged on the left and right sides. A first slider is slidably connected to the two first support plates. A support block is installed on the side of the two first sliders that are close to each other. A first soft pad is provided on the two support blocks.

[0007] Furthermore, it also includes a second soft pad, with a second soft pad provided on the front side wall of each of the two support blocks.

[0008] Furthermore, both the base plate and the vertical plates are made of granite.

[0009] Furthermore, it also includes a second support plate, a first guide rod, a sliding plate, a first spring, and a locking block. The second support plate is installed on the top center of the two first support plates respectively. Two first guide rods are provided in the middle of the two second support plates. Sliding plates are slidably connected to the two sets of first guide rods respectively. Locking blocks are symmetrically connected to the front and rear sides of the two sliding plates. A first spring is sleeved between the sliding plate and each locking block.

[0010] Furthermore, it also includes slide rails, second sliders, motors, screws, and a third support plate. Slide rails are vertically installed on the left and right side walls of the vertical plate, and second sliders are slidably connected to the two slide rails. Motors are installed in the middle of the two second sliders, and the output shafts of the two motors are connected to screws. The front ends of the two screws extend forward to be rotatably connected to the front of the corresponding second sliders. The third support plate is threadedly connected to the two screws.

[0011] Furthermore, it also includes a second guide rod and a second spring. The third support plate has multiple second guide rods slidably connected in a straight line. The rear ends of each second guide rod are connected to a third soft pad. A second spring is fitted on each second guide rod between the third support plate and the third soft pad.

[0012] The present invention has the following advantages: 1. The present invention uses a granite base plate and a vertical plate to form a high-precision benchmark, and is connected firmly with a connecting and fixing plate; the first support plate, the first slider, the support block and the first soft pad provide stable support for the workpiece, ensuring accurate positioning of the workpiece and effectively guaranteeing the accuracy of verticality measurement.

[0013] 2. This utility model, through the cooperation of the second support plate, the first guide rod, the sliding plate, the clamping block and the first spring, can adaptively fit the end face of the workpiece and apply force evenly, effectively avoiding the workpiece deformation due to clamping and affecting the measurement accuracy, and ensuring the stable and reliable positioning of the workpiece on the vertical plate.

[0014] 3. This utility model uses a motor to drive the screw to rotate, which in turn drives the third support plate, which is threaded to it, to move back and forth. The cooperation of the second guide rod, the second spring, and the third soft pad on the third support plate can apply a uniform and controllable clamping force to the workpiece, effectively preventing the workpiece from shifting during the measurement process and ensuring the repeatability and reliability of high-precision vertical measurement.

Detailed Implementation

[0024] Example: A high-precision vertical measurement worktable based on a horizontal base support, such as... Figure 1 , Figure 2 and Figure 3As shown, the system includes a base plate 1, a connecting and fixing plate 11, a vertical plate 12, a first support plate 2, a first slider 21, a support block 22, a first soft pad 23, and a second soft pad 24. A vertical plate 12 is screwed onto the top of the base plate 1 via the connecting and fixing plates 11, which are symmetrically arranged on the left and right sides. Both the base plate 1 and the vertical plate 12 are made of granite. Multiple mounting holes 13 are evenly opened on the front and rear side walls of the vertical plate 12 and on the top surface of the base plate 1. The first support plate 2 is screwed onto the lower front side wall of the vertical plate 12 via the multiple mounting holes 13. The first slider 21 is slidably connected to the two first support plates 2. A support block 22 is installed on the side of the two first sliders 21 that is close to each other. The first soft pad 23 is provided on the two support blocks 22. The second soft pad 24 is provided on the front side wall of the two support blocks 22.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, it also includes a second support plate 3, a first guide rod 31, a sliding plate 32, a first spring 33, and a locking block 34. The second support plate 3 is installed on the top center of the two first support plates 2 respectively. Two first guide rods 31 are provided in the middle of the two second support plates 3. Sliding plates 32 are slidably connected to the two sets of first guide rods 31 respectively. Locking blocks 34 are symmetrically connected to the front and rear sides of the two sliding plates 32. A first spring 33 is sleeved between the sliding plate 32 and each locking block 34.

[0026] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a slide rail 4, a second slider 41, a motor 42, a screw 43, a third support plate 44, a second guide rod 45, and a second spring 46. Slide rails 4 are vertically installed on the left and right side walls of the vertical plate 12, and second sliders 41 are slidably connected to the two slide rails 4. Motors 42 are installed in the middle of the two second sliders 41, and the output shafts of the two motors 42 are respectively connected to screws 43. The front ends of the two screws 43 extend forward and are rotatably connected to the front of the corresponding second slider 41. The two screws 43 are threadedly connected to the third support plate 44. The third support plate 44 is slidably connected to multiple second guide rods 45 evenly arranged in a straight line. The rear ends of each second guide rod 45 are connected to a third soft pad. A second spring 46 is sleeved on each second guide rod 45 between the third support plate 44 and the third soft pad.

[0027] When this device is needed, firstly, a vertical plate 12 is securely connected to the top of the base plate 1 via connecting and fixing plates 11 symmetrically arranged on the left and right sides. Both the base plate 1 and the vertical plate 12 are made of granite, which has an extremely low coefficient of thermal expansion and excellent long-term dimensional stability, thereby ensuring that the horizontal reference plane of the base plate 1 and the vertical reference plane of the vertical plate 12 have extremely high perpendicularity accuracy, providing a solid and reliable geometric basis for the entire measurement process.

[0028] Subsequently, the workpiece to be tested is prepared and positioned. Based on the structural characteristics of the workpiece, multiple mounting holes 13 are evenly opened on the front and rear side walls of the vertical plate 12. The workpiece to be tested is firmly installed on the front or rear side of the vertical plate 12 using bolts, pressure plates or other standard fasteners. The precise layout of these mounting holes 13 allows the workpiece to be fixed in various postures and positions, greatly enhancing the versatility and flexibility of the device, enabling it to adapt to workpieces of different sizes and shapes.

[0029] During the workpiece installation process, the first support plates 2, which are symmetrically installed on the left and right sides through multiple mounting holes 13 using screws, provide initial positioning and support for the workpiece. The first sliders 21 are slidably connected to the two first support plates 2 respectively. By adjusting the position of the first sliders 21 on the first support plates 2, workpieces of different widths can be accommodated. Support blocks 22 are installed on the side of the two first sliders 21 that are close to each other. The first soft pads 23 provided on the support blocks 22 can gently contact and support the bottom edge of the workpiece, preventing the workpiece from tipping over or sliding before fastening. The second soft pads 24 provided on the front sidewalls of the two support blocks 22 further increase the friction and cushioning of the contact surface, protecting the surface finish of the workpiece.

[0030] After the workpiece is initially positioned through the mounting hole 13, the operator can manually or with a tool push the sliding plate 32 to move it along the first guide rod 31 toward the workpiece. During this process, the clamping block 34 can automatically fit and press the front and rear end faces of the workpiece under the elastic force of the first spring 33. This structure can effectively compensate for the slight positional deviation that may exist when the workpiece is installed, ensure that the clamping force is evenly distributed, and avoid the workpiece from deforming due to single-point force, thereby ensuring the accurate positioning of the workpiece on the measurement reference.

[0031] To ensure the workpiece is absolutely stable during measurement, especially for tall or heavy workpieces, the vertically mounted slide rails 4 on the left and right side walls of the vertical plate 12 provide precise linear guidance for the lifting and lowering of the third support plate 44. After the motor 42 is started, its output shaft drives the screw 43 to rotate. The front ends of the two screws 43 are rotatably connected to the front of the corresponding second slider 41 through bearing seats, ensuring that the screws 43 can rotate stably. When the screws 43 rotate, the third support plate 44 will move back and forth along the slide rails 4 under the drive of the screws 43.

[0032] When the second slider 41 drives the third support plate 44 to descend to the top of the workpiece, the multiple second guide rods 45, which are evenly arranged and slidably connected along a straight line on the third support plate 44, begin to contact the workpiece. As the third support plate 44 continues to descend, the second spring 46 is gradually compressed, eventually causing the third soft pad to press against the top of the workpiece with uniform and controllable elastic pressure. This design cleverly utilizes the buffering characteristics of the second spring 46 to ensure a gentle pressing process and avoid rigid impacts that could cause workpiece displacement or damage to the measurement reference surface. At the same time, the third soft pad effectively protects the top surface of the workpiece. After the workpiece is fixed, height gauges, dial indicators, and other measuring tools can be used to measure the verticality with the vertical plate 12 as the reference surface. Because the workpiece is accurately positioned and clamped stably, the measurement results are accurate and reliable.
