Description

Technical Field

[0001] This utility model relates to the field of coordinate measuring technology, and in particular to a coordinate measuring lifting support. Background Technology

[0002] Coordinate measuring machine (CMM) inspection is the process of using a CMM to inspect and measure the form and position tolerances of a workpiece, determining whether the workpiece's error is within the tolerance range. With the rapid development of the modern automotive, aerospace, and machining industries, CMM has become a routine inspection method.

[0003] Current coordinate measuring machines (CMMs) are convenient for inspecting regular products, allowing for direct measurement. However, when inspecting irregularly shaped products, specialized fixtures are required. Existing fixtures often have a single function, suitable only for one or a few types of products. When dealing with a large variety of irregularly shaped products, multiple specialized fixtures often need to be designed for measurement. Measuring different irregularly shaped products requires frequent fixture changes, reducing measurement efficiency and significantly increasing the workload for the measuring operator.

[0004] For example, CN106017380A, published on October 12, 2016, discloses a coordinate measuring machine (CMM) support, including a base plate and support columns. At least three support columns are provided, vertically distributed and fixed to the base plate. Each support column has a fixing block installed at its top. One fixing block has a Y-axis positioning pin, and another has an XY-axis positioning pin. The remaining fixing blocks, excluding those with Y-axis or XY-axis positioning pins, each have a Z-axis positioning pin. The aforementioned support structure is fixed, and when products of different heights are placed on it, the ends of the products easily exceed the travel of the CMM, resulting in poor practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a more practical coordinate measuring machine lifting bracket. This invention adjusts the height of the shelf on the bracket by adjusting the components, thereby adjusting the height of items on the shelf and preventing products from exceeding the travel range of the coordinate measuring machine, thus improving practicality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a three-coordinate measuring lifting bracket, including a bracket, a shelf on the bracket, and a driving component for driving the shelf to move on the bracket.

[0007] The drive assembly includes a cylinder mounted on a bracket, and the piston of the cylinder is connected to the shelf via a floating joint.

[0008] The shelf is equipped with a guide rod, and the bracket is equipped with a linear bearing. The guide rod is connected to the linear bearing.

[0009] A turntable is provided on one side of the bracket, and an adjustment component for adjusting the angle of the bracket is provided on the turntable.

[0010] The adjustment assembly includes a bearing seat connected to a turntable, a lead screw on the bearing seat, a sleeve on the lead screw, a connecting rod between the sleeve and a bracket, one end of the connecting rod being hinged to the bracket, the other end of the connecting rod being hinged to the sleeve, a rotating rod on the bracket, and a fixed rod on the turntable, the fixed rod being hinged to the rotating rod.

[0011] The bracket is equipped with two rotating rods, and the turntable is equipped with two fixed rods.

[0012] The lead screw has a handle at its end.

[0013] The turntable has a base plate on one side, and a rotor is mounted on the base plate. The rotor is connected to the turntable.

[0014] The beneficial effects of this utility model are:

[0015] The item to be measured is placed on the shelf for measurement. When the height of the support plate needs to be adjusted, the drive component on the bracket will work to adjust the distance between the bracket and the shelf, thereby adjusting the height of the item on the shelf to prevent the product from being too high and exceeding the travel of the three coordinate measuring machine, thus improving its practicality.

[0016] The stable height adjustment of the platform is achieved by a drive assembly consisting of a cylinder and a floating joint. The angle adjustment of the bracket and the platform is achieved by an adjustment assembly consisting of a lead screw, a sleeve, a connecting rod, a fixed rod, and a rotating rod. This allows for the adjustment of the angle of the upper surface of the product on the platform, ensuring that the upper surface of the product is as perpendicular as possible to the probe for easy measurement.

[0017] The rotor and turntable on the base plate work together to make the platform able to rotate the product in a circular motion, thereby rotating a feature on the upper surface of the product onto the X or Y axis of the coordinate measuring machine, making it easier for the operator to measure.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figure 1-2 As shown, the coordinate measuring lifting support includes a support 9, a shelf 12 on the support 9, and a driving component on the support 9 to drive the shelf 12 to move. Specifically, the shelf 12 is circular, and both the shelf 12 and the support 9 have through holes.

[0024] When in use, the item to be measured is placed on the shelf 12 for measurement. When the height of the support plate 12 needs to be adjusted, the drive component on the bracket 9 works to adjust the distance between the bracket 9 and the shelf 12, thereby adjusting the height of the item on the shelf 12 to prevent the product from being too high and exceeding the travel of the three coordinate measuring machine, thus improving its practicality.

[0025] Specifically, the drive assembly includes a cylinder 10 mounted on the bracket 9. The piston of the cylinder 10 is connected to the shelf 12 via a floating joint 11. When the cylinder 10 operates, the piston moves the floating joint 11, which in turn moves the shelf 2, thereby adjusting the position of the shelf 12 on the bracket 9. In this embodiment, there are two cylinders 10, and the floating joint 11 is connected to the piston of the cylinder 10 via bolts.

[0026] The shelf 12 is provided with a guide rod 13, and the bracket 9 is provided with a linear bearing 14. The guide rod 13 is connected to the linear bearing 14. The precise linear movement of the shelf 12 on the bracket 9 is achieved by setting the guide rod 13 and the linear bearing 14. Specifically, one end of the guide rod 13 is welded to the shelf 12, and there are two guide rods 12 and two linear bearings 14.

[0027] A turntable 3 is provided on one side of the bracket 9. An adjustment component is provided on the turntable 3 to adjust the angle of the bracket 9. The angle of the bracket 9 and the shelf 12 is adjusted by the adjustment component, thereby realizing the angle of the upper surface of the product on the shelf 12, so that the upper surface of the product is as perpendicular as possible to the probe, which facilitates measurement.

[0028] Specifically, the adjustment assembly includes a bearing seat 16 connected to the turntable 3, a lead screw 4 on the bearing seat 16, a sleeve 6 on the lead screw 4, a connecting rod 15 between the sleeve 6 and the bracket 9, one end of the connecting rod 15 being hinged to the bracket 9, and the other end of the connecting rod 15 being hinged to the sleeve 6, a rotating rod 8 on the bracket 9, and a fixed rod 7 on the turntable 3, the fixed rod 7 being hinged to the rotating rod 8. Rotating the lead screw 4 causes the sleeve 6 to move, and the sleeve 6 moves to one end of the connecting rod 8. Since the rotating rod 8 on the other end of the bracket 9 is hinged to the fixed rod 7 on the turntable 3, the angle of the bracket 9 can be adjusted.

[0029] Specifically, the bracket 9 is provided with two rotating rods 8, and the turntable 3 is provided with two fixed rods 7, so that the bracket 9 can be stably placed on the turntable 3 by means of the two rotating rods 8 and the fixed rods 7.

[0030] The end of the lead screw 4 is provided with a handle 5, which makes it easy to rotate the lead screw 4 by turning the handle 5. Specifically, the handle 5 is welded to the right end of the lead screw 4.

[0031] A base plate 1 is provided on one side of the turntable 3, and a rotor 2 is provided on the base plate 1. The rotor 2 is connected to the turntable 3. The rotor 2 on the base plate 1 and the turntable 3 cooperate with each other, so that the bracket 9 and the platform 12 on the turntable 3 can be rotated. In this way, a certain feature on the upper surface of the product on the platform 12 can be rotated to the X or Y axis of the coordinate measuring machine, which is convenient for the measuring operator to measure. In this embodiment, the two ends of the rotor 2 are connected to the turntable 3 and the base plate 1 respectively through bearings, so as to facilitate the convenient rotation of the turntable 3 on the base plate 1.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
