Description

Technical Field

[0001] The utility model belongs to the technical field of three-coordinate universal tooling clamps, in particular to a three-coordinate universal tooling clamp. Background Art

[0002] Three-dimensional coordinate measurement (CMM) is a precision measurement method for inspecting parts. It is widely used in modern industries such as machinery manufacturing and the automotive industry. Three-dimensional coordinate measurement (CMM) uses a CMM to inspect and measure the form and position tolerances of parts, determining whether the part's errors are within the tolerance range.

[0003] For example, the Chinese patent with announcement number CN214135638U discloses a three-coordinate universal fixture, including a fixture base and a support platform. The support platform is arranged above the fixture base, and a first flat-nose jaw portion and a second flat-nose jaw portion are arranged on both sides of the support platform. A slide rail is provided above the support platform, one end of the slide rail penetrates the first flat-nose jaw portion, and the other end penetrates the second flat-nose jaw portion. The second flat-nose jaw portion slides along the slide rail to move closer to or away from the second flat-nose jaw portion; the first jaw portion and the second jaw portion both include a mounting portion, a support portion, and a clamping portion, and parts are clamped between the clamping portions on the first jaw portion and the second jaw portion. The utility model clamps parts between the clamping portions on the first jaw portion and the second jaw portion, so that parts of different sizes are stably fixed on the fixture, and the adjustment is stable and convenient, and the consistency in the X, Y, and Z three-dimensional directions is maintained without affecting the form and position tolerances of the parts, ensuring that the parts can be accurately clamped and measured.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when clamping, the device only clamps the part at two locations, using the first and second jaws. Parts clamped at two locations are more susceptible to vibration, causing displacement, thereby affecting the reliability of the measurement results. In addition, the device is not convenient for fixing cylindrical parts, and other clamps are required to fix them, which is relatively inconvenient. In view of this, we propose a three-coordinate universal tooling fixture. Utility Model Content

[0006] The purpose of the present invention is to provide a three-coordinate universal fixture to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a three-coordinate universal fixture, comprising:

[0008] A base, the top of the base is provided with a slide groove, two movable splints are slidably installed in the slide groove, and a placement plate is fixedly installed on opposite sides of the two movable splints. A limiting groove is provided on the top of the placement plate, two sliding plates are slidably installed in the limiting groove, and a two-way threaded rod is rotatably installed in the limiting groove, and one end of the two-way threaded rod passes through the two sliding plates and one side of the limiting groove and extends to the outside;

[0009] A driving assembly is located in the base and is used to drive the two movable clamping plates to move closer to or away from each other;

[0010] Two grooves, the two grooves are respectively opened on the top of the two movable clamping plates, the connecting plates are inserted and installed in the grooves, and the second clamping plate and the first clamping plate are respectively fixedly installed on the opposite sides of the two connecting plates;

[0011] Two fixing components are respectively located in the two movable clamping plates and are used to fix the two connecting plates respectively.

[0012] In this technical solution, when fixing a cylindrical part, the staff places the cylindrical part between the first and second clamping plates. Subsequently, the driving assembly is provided to drive the two movable clamping plates closer to each other, and the two movable clamping plates will respectively drive the two connecting plates closer to each other, so that the two connecting plates respectively drive the first and second clamping plates closer to each other, until the opposite sides of the first and second clamping plates contact and clamp the cylindrical part. If the cylindrical part is thinner, the first clamping plate will slide into the second clamping plate, ensuring that cylindrical parts of different thicknesses can be effectively clamped.

[0013] If a rectangular part is to be clamped, the two fixing assemblies are used to release the fixation of the two connecting plates, and then the connecting plates can be pulled out of the corresponding grooves. Subsequently, the two movable clamps can be adjusted to the appropriate position through the driving assembly, so that the two placement plates are close to each other, so that the rectangular part can be placed on the two placement plates and the rectangular part is located inside the four sliding plates. Subsequently, the two movable clamps can be continued to be close to each other until the two movable clamps clamp the rectangular part. Subsequently, the operating disk 2 on the two-way threaded rod 2 can be turned by hand and drive the two-way threaded rod 2 to rotate. Under the action of the thread, the two-way threaded rod 2 will drive the two sliding plates close to each other until the two sliding plates contact the rectangular part and clamp it, ensuring that the rectangular part will not move forward, backward, left or right. At this time, two of the sliding plates will clamp the rectangular part. Through the above operation, the other two sliding plates can clamp the rectangular part, and the clamping and fixing effect is better.

[0014] In the above technical solution, further, the driving component includes:

[0015] A two-way threaded rod is rotatably installed in the slide groove, one end of the two-way threaded rod passes through two movable splints and one side of the slide groove and extends to the outside, and one end of the two-way threaded rod is fixedly installed with an operating panel.

[0016] In this technical solution, the operating disk on the bidirectional threaded rod is rotated by hand to drive the bidirectional threaded rod to rotate. Under the action of the thread, the bidirectional threaded rod will drive the two movable splints closer to each other.

[0017] In the above technical solution, further, the bidirectional threaded rod 1 is provided with two sections of threads with opposite rotation directions, and the movable clamping plate is threadedly connected to the bidirectional threaded rod 1.

[0018] In this technical solution, under the action of the thread, it is ensured that when the bidirectional threaded rod rotates, it can drive the two movable clamping plates to move closer to or away from each other.

[0019] In the above technical solution, further, the fixing assembly includes:

[0020] A limiting rod is inserted and installed in the movable splint, one end of the limiting rod passes through the connecting plate and extends to the outside and is provided with a through slot, and an insertion rod is inserted and installed in the through slot.

[0021] In this technical solution, when disassembling the two connecting plates, the staff pulls the two rods upward by hand so that the two rods are pulled out from the corresponding through grooves. At this time, the limit rod will be released, and then the limit rod can be pulled by hand to completely pull the limit rod out from the movable splint and the connecting plate. At this time, the two connecting plates will be released, and then the connecting plates can be pulled out from the corresponding grooves.

[0022] In the above technical solution, further, the limiting rod is plugged into the connecting plate, and the plugging rod is in contact with the movable splint.

[0023] In this technical solution, it is ensured that the limiting rod can be inserted into the connecting plate; and it is ensured that the insertion rod can fix the position of the limiting rod.

[0024] In the above technical solution, further, the top of the sliding plate and the top of the movable splint are located on the same horizontal line, the second bidirectional threaded rod is provided with two sections of threads with opposite rotation directions, and the sliding plate is threadedly connected to the second bidirectional threaded rod.

[0025] In this technical solution, it is ensured that the two movable clamps can clamp the rectangular parts; under the action of the thread, it is ensured that the two sliding plates can be driven to move closer to or away from each other when the two-way threaded rod rotates.

[0026] In the above technical solution, further, the first clamping plate is slidably connected to the second clamping plate, and an operating panel 2 is fixedly installed on one end of the second bidirectional threaded rod.

[0027] In this technical solution, it is ensured that the first clamping plate can slide inside the second clamping plate; it is ensured that the two-way threaded rod second can be rotated through the operating disk second, which is more convenient.

[0028] The beneficial effects of the utility model are:

[0029] The three-coordinate universal fixture can fix not only rectangular parts but also cylindrical parts through the cooperation among the arranged base, movable clamp, connecting plate, clamp one, clamp two, bidirectional threaded rod one, sliding plate, placement plate, groove, bidirectional threaded rod two, limit slot fixing assembly and driving assembly, which is more convenient to use. Moreover, when fixing rectangular parts, the rectangular parts can be fixed at multiple locations, which can effectively avoid the displacement of the rectangular parts due to the influence of vibration, thereby ensuring the reliability of the measurement results.
