Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a workpiece clamping device for milling grooves in a motorcycle cylinder block. Background Technology

[0002] Milling is a critical process in the machining of motorcycle engine cylinder blocks. Traditional cylinder block milling usually uses general-purpose or special-purpose fixtures for clamping, which has low clamping flexibility and therefore does not meet current requirements.

[0003] The existing publication number CN212823966U discloses a workpiece fixture for a milling machine for boring semi-circular holes in a lower cylinder block. Fixed blocks are installed at both ends of the main body and the outer side of the auxiliary adjusting fixture. A support fixing plate is installed on the outer side of the fixed blocks, and a fixed support block is installed below the support fixing plate. A sliding fixing sleeve is installed below the auxiliary adjusting fixture, and a transmission screw is installed inside the sliding fixing sleeve. Rotation stabilizing blocks are provided at the lower ends of both the main body and the auxiliary adjusting fixture, and rotation stabilizing grooves are provided at the upper ends of the sliding fixing sleeve and the fixed support block. The rotation of the transmission screw drives the sliding fixing sleeve to move, allowing for better adjustment of the distance between the fixtures according to the machining length, making adjustment more convenient. The rotation stabilizing block rotates within the rotation stabilizing groove, ensuring better stability of the clamping rotation performance and improving overall stability. This solves the problem of low clamping flexibility in existing workpiece fixtures for milling semi-circular holes in lower cylinder blocks.

[0004] However, the workpiece fixture for the milling machine for boring semi-circular holes in the lower cylinder block mentioned above still requires manually rotating the transmission screw to adjust the fixture spacing, which is cumbersome and time-consuming. Utility Model Content

[0005] The purpose of this utility model is to provide a workpiece clamping device for milling grooves in motorcycle cylinder blocks, which solves the problem that the existing workpiece clamping device for milling grooves in the lower cylinder block requires manual rotation of the transmission screw to adjust the clamping distance, which is cumbersome and time-consuming.

[0006] To achieve the above objectives, this utility model provides a workpiece clamping device for milling grooves in motorcycle cylinder blocks, including a worktable, a lifting assembly, and a fixing assembly;

[0007] The fixing assembly includes a fixing column, a fixing block, a sliding rod, and a power component. The fixing column is connected to the lifting assembly. There are multiple fixing blocks, which are distributed on the outside of the fixing column. The sliding rod is fixedly connected to the side of each fixing block near the fixing column. The sliding rod is slidably connected to the fixing column and extends into the interior of the fixing column. The power component is connected to the sliding rod. The lifting assembly is connected to the worktable.

[0008] The power component includes a push block and a connecting spring. The push block is fixedly connected to one end of each slide rod away from the fixed block. The two ends of the connecting spring abut against the push block and the fixed post, respectively, and are located on the outside of the slide rod.

[0009] The power component further includes a push rod that extends into the interior of the fixed column and cooperates with the push block.

[0010] The lifting assembly includes a lifting platform, a lifting screw, and a lifting slider. The lifting platform is fixedly connected to the worktable and located on top of the worktable. The lifting screw is rotatably connected to the lifting platform, and the lifting slider is connected to the lifting screw.

[0011] The lifting assembly also includes a mounting platform, which is fixedly connected to the lifting slider and to the fixed column.

[0012] This utility model discloses a workpiece clamping device for milling grooves in a motorcycle cylinder block. The worktable provides support, and the lifting assembly drives the fixing assembly to move up and down for milling. Multiple fixing blocks are arranged on the outer side of the fixing column. A power component extends into the interior of the fixing column, pushing the slider outward, which in turn pushes the fixing blocks outward. In use, the workpiece is placed on the outer side of the fixing column, and then the fixing blocks are moved outward to abut against the inner wall of the workpiece, thus fixing the workpiece before milling. The operation is simple, convenient, and time-saving. Attached Figure Description

[0018] 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.

[0019] The first embodiment of this application is as follows:

[0020] Please see Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the workpiece clamping device for milling grooves in a motorcycle cylinder block according to the first embodiment of this utility model. Figure 2 This is a cross-sectional structural schematic diagram of the workpiece clamping device for milling grooves in a motorcycle cylinder block according to the first embodiment of this utility model. Figure 3 This is the utility model Figure 2 Enlarged view of point A.

[0021] This utility model provides a workpiece clamping device for milling grooves in motorcycle cylinder blocks: it includes a worktable 101, a lifting assembly, and a fixing assembly. The fixing assembly includes a fixing column 102, a fixing block 103, a slide rod 104, and a power component. The power component includes a push block 105, a connecting spring 106, and a push rod 107. The lifting assembly includes a lifting platform 108, a lifting screw 109, a lifting slider 110, and a mounting platform 111. The aforementioned solution solves the labor shortage problem of existing lower cylinder block boring semi-circular hole milling machines. It can be understood that the aforementioned solution can also be used to solve the problem of vertical adjustment.

[0022] In this specific embodiment, the fixed column 102 is connected to the lifting assembly, and there are multiple fixed blocks 103. The multiple fixed blocks 103 are distributed on the outside of the fixed column 102. Each fixed block 103 is fixedly connected to the slide rod 104 on the side near the fixed column 102. The slide rod 104 is slidably connected to the fixed column 102 and extends into the interior of the fixed column 102. The power component is connected to the slide rod 104, and the lifting assembly is connected to the worktable 101. The worktable 101 is used for support. The lifting assembly drives the fixed column 102 to move up and down. The outer diameter of the fixed column 102 is smaller than the inner diameter of the cylinder. There are multiple fixed blocks 103, which are evenly distributed in a circle along the axis of the fixed column 102. Each fixed block 103 is fixed with a slide rod 104. The other end of the slide rod 104 extends into the interior of the fixed column 102 and is slidably connected to the fixed column 102. The power component is used to drive the slider to move outward along the axis of the fixed column 102, thereby driving the fixed block 103 to move outward until it abuts against the inner wall of the cylinder and fixes the cylinder.

[0023] In this configuration, the end of each slide rod 104 furthest from the fixed block 103 is fixedly connected to the push block 105. The two ends of the connecting spring 106 abut against the push block 105 and the fixed post 102, respectively, and are located outside the slide rod 104. The end of the slide rod 104 extending into the fixed post 102 is fixed to the push block 105. The push block 105 has an inclined surface on its upper surface. The connecting spring 106 is sleeved on the outside of the slide rod 104. During the outward movement of the push block 105, the connecting spring 106 is compressed. When it is no longer necessary to hold the cylinder, the push block 105 loses force, and the elastic force of the connecting spring 106 causes the push block 105 to reset, thereby resetting the fixed block 103, facilitating the removal of the cylinder.

[0024] Secondly, the push rod 107 extends into the interior of the fixed column 102 and cooperates with the push block 105. The push rod 107 extends into the interior of the fixed column 102 and cooperates with the inclined surface of the push block 105. The top of the push rod 107 is equipped with an electric telescopic rod or cylinder to drive it to move up and down. In use, it drives the push rod 107 to move downward, so that it contacts the push block 105, thereby pushing the push block 105 to move outward.

[0025] Meanwhile, the lifting platform 108 is fixedly connected to the worktable 101 and located on top of the worktable 101. The lifting screw 109 is rotatably connected to the lifting platform 108, and the lifting slider 110 is connected to the lifting screw 109. The lifting platform 108 supports the rotation of the lifting screw 109. A motor is connected to the top of the lifting screw 109, which is driven to rotate. The lifting slider 110 is threadedly engaged with the lifting screw 109 and moves up and down following its rotation. A guide rod is provided on the lifting platform 108, which passes through the lifting slider 110 to guide its movement.

[0026] In addition, the mounting platform 111 is fixedly connected to the lifting slider 110 and to the fixing column 102. The mounting platform 111 is fixed on the lifting slider 110 and moves up and down with the lifting slider 110. The bottom of the mounting platform 111 is fixed to the fixing column 102 and also has a suction cup connected to an air pump, which generates an adsorption force on the outside of the fixing column 102. The mounting platform 111 is also used to mount the push rod 107, allowing the push rod 107 to move up and down and extend into the interior of the fixing column 102.

[0027] Using the workpiece clamping device for milling grooves in a motorcycle cylinder block according to this embodiment, the cylinder block is fitted onto the outside of the fixing post 102. The bottom of the fixing post 102 has a positioning platform for positioning the cylinder block. At the same time, the suction cups around the fixing platform generate an adsorption force to limit the cylinder block on the fixing post 102. The push rod 107 moves downward, pushing the push block 105 outward, which in turn drives the slide rod 104 and the fixing block 103 to move outward and abut against the inner wall of the cylinder block, thereby fixing the cylinder block. At this time, the lifting screw is driven... The rotation of lever 109 causes the lifting slider 110 and the mounting platform 111 to move downwards, which in turn causes the fixed column 102 and the cylinder to move downwards, sending the cylinder into the milling tool for milling. After milling, the lifting screw 109 reverses, causing the cylinder to move upwards, the air pump stops running, and the push rod 107 moves upwards. Then, the push block 105 is reset under the elastic force of the connecting spring 106, and the fixed block 103 is away from the inner wall of the cylinder, so the cylinder can be easily removed. It is simple to operate and saves time.

[0028] 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.
