Technical Field
[0001] This utility model relates to the field of pneumatic rotary indexing technology, specifically a pneumatic rotary indexing plate. Background Technology
[0002] The pneumatic rotary indexing table is a precision positioning device widely used in automated production, machining, and assembly. It uses compressed air as a power source to achieve precise indexing rotation of the rotary platform, enabling the workpiece to be positioned quickly and accurately to the preset processing or operation position, greatly improving production efficiency and processing accuracy, and meeting the needs of multi-station continuous operation. The pneumatic rotary indexing table consists of a rotary table body, a pneumatic drive system, an indexing and positioning mechanism, a control system, and a fixed fixture. In the initial state, the rotary table is stationary and locked, and the workpiece is fixed on the table surface by the fixed fixture. When a start signal is received, the control system opens the air circuit valve, and compressed air enters the cylinder. The piston of the cylinder begins to move linearly under the action of air pressure. With the help of a mechanical transmission structure, the linear motion is converted into the rotational motion of the rotary table.
[0003] In the existing technology, the fixing fixture on the pneumatic rotary indexing plate needs to be adjusted by the operator by rotating the handwheel. Therefore, every time a workpiece is fixed, the handwheel needs to be rotated and the fixing fixture needs to be moved towards the workpiece, which makes the operation of fixing the workpiece quite troublesome. Moreover, different fixing fixtures need to be disassembled and assembled for fixing different workpieces, which makes the labor intensity of the operator high. Therefore, a pneumatic rotary indexing plate is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a pneumatic rotary indexing plate, which has the advantages of easy automatic fixing and quick disassembly and assembly of fixing fixtures. It solves the problem that the fixing fixtures on the pneumatic rotary indexing plate require operators to rotate the handwheel for adjustment. Therefore, every time a workpiece is fixed, the handwheel needs to be rotated and the fixing fixture needs to be moved towards the workpiece, which makes the workpiece fixing operation more troublesome. Moreover, different fixing fixtures need to be disassembled and assembled for different workpieces, which increases the labor intensity of the operators.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic rotary indexing plate, including a tooling table, a cylinder being provided on the tooling table, a rotary table being provided on the tooling table, and a fixing fixture being provided on the rotary table;
[0006] The fixing fixture includes a connecting frame slidably mounted on a rotary table. The bottom of the connecting frame is provided with a guide component for limiting its sliding trajectory. A feed component for controlling the movement of the connecting frame is fixedly mounted on the rotary table. A displacement sensor for detecting its movement distance is fixedly mounted on the connecting frame. A connecting block is inserted into the inside of the connecting frame. A fixture body for clamping and fixing the workpiece is fixedly mounted at the bottom of the connecting block. A locking component for fixing the position of the connecting block is provided inside the connecting frame.
[0007] Furthermore, the locking assembly includes a mating plate, which is fixedly installed on the inner top wall of the connecting frame. One end of the mating plate extends through and into the interior of the connecting block. A threaded post is fixedly installed on the rear side wall of the inner cavity of the connecting frame. A positioning sleeve with one end extending through and into the interior of the connecting block and used to lock the connecting block is installed on the threaded post.
[0008] Furthermore, the cylinder is fixedly installed on one side of the tooling table, and one end of the cylinder passes through and extends into the interior of the tooling table. The rotary table is rotatably installed on the tooling table, and the number of the fixing fixtures is three, which are centrally symmetrically distributed on the rotary table.
[0009] Furthermore, the guiding component includes a guide block and a guide groove. The guide block is fixedly installed on the back of the connecting frame, the guide groove is opened on the rotary table, and the guide block is slidably installed inside the guide groove.
[0010] Furthermore, the feeding component includes a mounting frame and an electric push rod. The mounting frame is fixedly mounted on the outer peripheral wall of the rotary table, and the electric push rod is fixedly mounted on the mounting frame. The telescopic end of the electric push rod is fixedly connected to the guide block.
[0011] Furthermore, the positioning sleeve includes a threaded sleeve and three rectangular blocks. The three rectangular blocks are all fixedly installed on the outer surface of the threaded sleeve and are centrally symmetrically distributed. The threaded sleeve is threadedly installed on the outer surface of the threaded post.
[0012] Furthermore, the connecting block has a rectangular groove inside that matches the mating plate, one end of the mating plate passes through and extends into the rectangular groove, and the front of the connecting block has a circular groove that matches the threaded sleeve, and the circular groove is connected to the rectangular groove.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] This pneumatic rotary indexing table, equipped with a fixed clamp, utilizes an electric push rod in the feed component to control the movement of a guide block in the guide component. This movement of the guide block causes the connecting frame to move synchronously, which in turn drives the clamp body to be automatically fed in via the connecting block inside the connecting frame. This replaces manual adjustment by the operator, making the operation of fixing the workpiece more convenient. Furthermore, by rotating the positioning sleeve on the threaded column, the positioning sleeve can be disengaged from inside the connecting block, allowing the operator to remove the clamp body and the connecting block. This reduces the labor intensity of the operator in disassembling and replacing different clamp bodies, thus enhancing the practicality of the pneumatic rotary indexing table.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 3 The pneumatic rotary indexing plate in this embodiment includes a tooling table 1, a cylinder 2 on the tooling table 1, a rotary table 3 on the tooling table 1, and a fixing fixture on the rotary table 3. The cylinder 2 is fixedly installed on one side of the tooling table 1, and one end of the cylinder 2 passes through and extends into the interior of the tooling table 1. The rotary table 3 is rotatably installed on the tooling table 1. The number of fixing fixtures is three and they are centrally symmetrically distributed on the rotary table 3.
[0021] In this embodiment, the fixing fixture includes a connecting frame 41 slidably mounted on a rotary table 3. The bottom of the connecting frame 41 is provided with a guide component 42 for limiting its sliding trajectory. The guide component 42 includes a guide block and a guide groove. The guide block is fixedly mounted on the back of the connecting frame 41, and the guide groove is opened on the rotary table 3. The guide block is slidably mounted inside the guide groove to limit the movement trajectory of the connecting frame 41. A feed component 43 for controlling the movement of the connecting frame 41 is fixedly mounted on the rotary table 3. A displacement sensor 44 for detecting its movement distance is fixedly mounted on the connecting frame 41. A connecting block 45 is inserted into the inside of the connecting frame 41. A fixture body 46 for clamping and fixing the workpiece is fixedly mounted at the bottom of the connecting block 45. A locking component for fixing the position of the connecting block 45 is provided inside the connecting frame 41.
[0022] The feeding component 43 includes a mounting frame and an electric push rod. The mounting frame is fixedly installed on the outer peripheral wall of the rotary table 3, and the electric push rod is fixedly installed on the mounting frame. The telescopic end of the electric push rod is fixedly connected to the guide block, so as to facilitate the use of the electric push rod to control the guide block to drive the connecting frame 41 to move.
[0023] By adopting the above technical solution, the electric push rod in the feed component 43 is activated, which extends and drives the guide block in the guide component 42 to move in the guide groove. The moving guide block drives the connecting frame 41 to move synchronously, thereby controlling the feed of the fixture body 46 through the connecting frame 41, and realizing the rapid clamping and fixing of the workpiece using three fixture bodies 46.
[0024] In this embodiment, the locking assembly includes a mating plate 47, which is fixedly installed on the inner top wall of the connecting frame 41. One end of the mating plate 47 extends through and into the interior of the connecting block 45. A threaded post 48 is fixedly installed on the rear side wall of the inner cavity of the connecting frame 41. A positioning sleeve 49, which extends through and into the interior of the connecting block 45 and is used to lock the connecting block 45, is installed on the threaded post 48. The positioning sleeve 49 includes a threaded sleeve and three rectangular blocks. The three rectangular blocks are all fixedly installed on the outer surface of the threaded sleeve and are centrally symmetrically distributed. The threaded sleeve is threaded onto the outer surface of the threaded post 48, which facilitates the rotation of the positioning sleeve 49 and controls the back-and-forth movement of the positioning sleeve 49 on the threaded post 48.
[0025] The connecting block 45 has a rectangular groove inside that is compatible with the mating plate 47.

[0026] By adopting the above technical solution, the connecting block 45 at the top of the fixture body 46 is inserted into the interior of the connecting frame 41, so that the threaded post 48 passes through the rectangular groove and the circular groove. Then, the positioning sleeve 49 on the threaded post 48 is rotated, so that the positioning sleeve 49 moves and inserts into the circular groove on the front of the connecting block 45, thereby locking the position of the connecting block 45.
[0027] The working principle of the above embodiments is as follows:
[0028] When using this pneumatic rotary indexing table, the connecting block 45 on the top of the fixture body 46 is inserted into the interior of the connecting frame 41, so that the threaded post 48 passes through the rectangular groove and the circular groove. Then, the positioning sleeve 49 on the threaded post 48 is rotated, so that the positioning sleeve 49 moves and inserts into the circular groove on the front of the connecting block 45, thereby locking the position of the connecting block 45. Then, the electric push rod in the feed component 43 can be activated, so that the electric push rod extends and drives the guide block in the guide component 42 to move in the guide groove, so that the moving guide block drives the connecting frame 41 to move synchronously, thereby controlling the feed of the fixture body 46 through the connecting frame 41, realizing the quick clamping and fixing of the workpiece using three fixture bodies 46.
