Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a workpiece fixing clamp for milling machines. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to process various surfaces of a workpiece. When a milling machine processes a workpiece, it needs to use a fixture to fix the workpiece in order to prevent the workpiece from shifting during processing. However, conventional fixtures are difficult to fix for different workpieces.

[0003] Existing patent CN209887116U describes a milling machine workpiece fixing mechanism. Through the design of a wedge-shaped clamping block, an electric push rod, a first guide rod, and a second guide rod, the device can, on the one hand, freely adjust the position and size of the clamp for different workpieces, thereby improving the usability and versatility of the device; on the other hand, through a fine-tuning mechanism, the device can be finely adjusted to change the shape of the clamping block when clamping irregularly shaped workpieces, thereby increasing the application scenarios of the device and enhancing the clamping strength of the device for irregularly shaped workpieces.

[0004] However, when using a milling machine workpiece fixing mechanism based on an existing patent, the support plate used to support the workpiece limits the travel of the moving seat. If the workpiece is smaller than the support plate, the wedge-shaped clamps on both sides of the moving seat cannot clamp the workpiece, thus making it impossible to clamp small workpieces. Utility Model Content

[0005] The purpose of this utility model is to provide a milling machine workpiece fixing fixture, which solves the problem that the support plate used to support the workpiece in the aforementioned device restricts the travel of the moving seat. If the size of the workpiece is smaller than the support plate, the wedge-shaped clamping blocks on both sides of the moving seat cannot clamp the workpiece, thus making it impossible to clamp small workpieces.

[0006] To achieve the above objectives, this utility model provides a milling machine workpiece fixing fixture, including a base and a clamping device. The clamping device includes a workpiece placement plate, a support plate, a sliding clamp, and a transmission assembly. The support plate is fixedly installed on the base, and the workpiece placement plate is fixedly installed on the support plate and located on the side of the support plate away from the base. One side of the workpiece placement plate is provided with a receiving groove, and the side of the workpiece placement plate near the receiving groove is also provided with a dropping groove. The dropping groove communicates with the receiving groove. The sliding clamp is slidably installed on the workpiece placement plate through the transmission assembly, and the workpiece placement plate passes through the sliding clamp.

[0007] The transmission assembly includes a transmission screw and a threaded sleeve. The threaded sleeve is fixedly installed on the sliding clamp and passes through the sliding clamp. The transmission screw is rotatably installed on the support plate and threaded through the threaded sleeve.

[0008] The clamping device further includes a collection component, which includes a chip collection frame and a pull bracket. The chip collection frame is slidably mounted on the support plate and located within the receiving groove; the pull bracket is fixedly mounted on the chip collection frame.

[0009] The placement plate is further provided with a first baffle and a second baffle. The first baffle is fixedly installed on the placement plate. The second baffle is fixedly installed on the side of the placement plate near the first baffle. The sliding clamp is provided with a first through groove and a second through groove on the side near the first baffle and the second baffle, respectively.

[0010] The clamping device includes a fine-tuning component, which includes a movable disc and a fine-tuning bolt. The fine-tuning bolt is threaded through the sliding clamp. The movable disc is fixedly mounted on the fine-tuning bolt.

[0011] This utility model discloses a milling machine workpiece fixing fixture. In use, the workpiece is placed in the middle of the placement plate, and then the transmission screw is driven to rotate by a motor. Since the threads at both ends of the transmission screw turn in opposite directions, the threaded sleeves on both sides drive the sliding clamps fixedly connected to them to move towards each other. As the sliding clamps move, the workpiece is finally clamped by the sliding clamps on both sides, and then the workpiece can be processed by the milling machine. The first baffle and the second baffle prevent the waste chips generated during the processing from splashing out of the placement plate. The set groove allows the waste chips to enter the chip collection frame in the receiving groove. Thus, through the sliding cooperation between the placement plate and the sliding clamps on both sides, the placement plate provides support for the workpiece without hindering the movement stroke of the sliding clamps, thereby enabling the sliding clamps to clamp even small workpieces.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows:

[0018] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a milling machine workpiece fixing fixture according to this utility model. Figure 2 This is a schematic diagram of the transmission component of this utility model.

[0019] This utility model provides a milling machine workpiece fixing fixture: it includes a base 101 and a clamping device. The clamping device includes a workpiece placement plate 102, a support plate 103, a sliding clamping seat 104, and a transmission assembly. The transmission assembly includes a transmission screw 107 and a threaded sleeve 108. The clamping device also includes a collection assembly, which includes a chip collection frame 109 and a pull frame 110. The workpiece placement plate 102 is also provided with a first baffle 111 and a second baffle 112. The clamping device includes a fine-tuning assembly, which includes a movable disc 115 and a fine-tuning bolt 116. The aforementioned solution solves the problem that the support plate used to support the workpiece limits the travel of the movable seat. If the workpiece is smaller than the support plate, the wedge-shaped clamping blocks on both sides of the movable seat cannot clamp the workpiece, thus making it impossible to clamp small workpieces. The aforementioned solution can be used in the scenario of clamping workpieces in milling machine processing, and can also be used to solve the problem of clamping irregularly shaped workpieces.

[0020] In this embodiment, the sliding engagement between the placement plate 102 and the sliding clamps 104 on both sides allows the placement plate 102 to provide support for the workpiece without hindering the movement of the sliding clamps 104, thereby enabling the sliding clamps 104 to clamp smaller workpieces as well.

[0021] The support plate 103 is fixedly mounted on the base 101, and the placement plate 102 is fixedly mounted on the support plate 103, located on the side of the support plate 103 away from the base 101. One side of the placement plate 102 has a receiving groove 105, and the side of the placement plate 102 near the receiving groove 105 also has a dropping groove 106, which communicates with the receiving groove 105. The sliding clamp 104 is slidably mounted on the placement plate 102 via the transmission assembly, and the placement plate 102 passes through the sliding clamp 104. The support plate 103 is symmetrically arranged on the support plate 102. On both sides of the base 101, the placement plate 102 is welded to the top of the support plate 103 on both sides. The sliding clamp 104 is disposed on both sides of the placement plate 102. The transmission assembly can drive the sliding clamp 104 on both sides to move. In use, the workpiece is placed in the middle of the placement plate 102. The transmission assembly drives the sliding clamp 104 on both sides to move towards each other along the placement plate 102, so that the sliding clamp 104 clamps the workpiece, avoiding the movement stroke of the sliding clamp 104. Thus, the sliding clamp 104 can also clamp small workpieces.

[0022] Secondly, the threaded sleeve 108 is fixedly installed on the sliding clamp 104 and passes through the sliding clamp 104; the transmission screw 107 is rotatably installed on the support plate 103 and threadedly passes through the threaded sleeve 108. Each set of sliding clamps 104 is welded with a set of threaded sleeves 108. The inner side of the threaded sleeve 108 is provided with threads. The two ends of the transmission screw 107 have opposite threads. The transmission screw 107 is driven by a motor. In use, the transmission screw 107 rotates under the drive of the motor. Through the rotation of the transmission screw 107, the threaded sleeves 108 on both sides rotate simultaneously towards or in opposite directions, thereby realizing the movement drive of the threaded sleeves 108.

[0023] Furthermore, the chip collection frame 109 is slidably mounted on the support plate 103 and located within the receiving groove 105; the pull bracket 110 is fixedly mounted on the chip collection frame 109, which is located directly below the drop groove 106. The pull bracket 110 is fixed to the chip collection frame 109 with screws. The chip collection frame 109 is designed to prevent the collection of waste chips falling from the placement plate 102.

[0024] Furthermore, the first baffle 111 is fixedly installed on the placement plate 102; the second baffle 112 is fixedly installed on the side of the placement plate 102 near the first baffle 111. The sliding clamp 104 is provided with a first through groove 113 and a second through groove 114 on the side near the first baffle 111 and the second baffle 112, respectively. The first baffle 111 and the second baffle 112 are arranged opposite to each other on the front and rear sides of the placement plate 102. The first baffle 111 and the second baffle 112 are both fixed to the placement plate 102 by welding. The width of the first through groove 113 and the second through groove 114 is the same as the thickness of the first baffle 111 and the second baffle 112, respectively. By setting the first baffle 111 and the second baffle 112, it is possible to prevent the waste generated by the workpiece during processing from splashing out of the placement plate 102.

[0025] Finally, the fine-tuning bolt 116 is threaded through the sliding clamp 104; the movable disc 115 is fixedly mounted on the fine-tuning bolt 116. There are multiple sets of fine-tuning bolts 116 and movable discs 115, which are linearly and spaced apart on the sliding clamp 104. The movable disc 115 has a disc structure. By rotating the fine-tuning bolt 116, the movable disc 115 can move slightly on the sliding clamp 104, thereby enabling the movable disc 115 to make good contact with the irregular surface of the irregular workpiece, which facilitates the sliding clamp 104 to clamp the irregular workpiece.

[0026] In this embodiment, during use, the workpiece is placed in the middle of the placement plate 102, and then the transmission screw 107 is driven to rotate by the motor. Since the threads at both ends of the transmission screw 107 turn in opposite directions, the threaded sleeves 108 on both sides drive the sliding clamps 104 fixedly connected to them to move towards each other. As the sliding clamps 104 move, the workpiece is finally clamped by the sliding clamps 104 on both sides, and then the workpiece can be processed by a milling machine. The first baffle 111 and the second baffle 112 can prevent the waste chips generated during the processing from splashing out of the placement plate 102. The waste chips are allowed to enter the chip collection frame 109 in the receiving groove 105 by the set groove 106. Thus, through the sliding cooperation between the placement plate 102 and the sliding clamps 104 on both sides, the placement plate 102 can provide support for the workpiece without hindering the movement of the sliding clamps 104, so that the sliding clamps 104 can also clamp small workpieces.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
