Description

Technical Field

[0001] This utility model relates to the field of side-top clamping technology, and more specifically, it relates to a side-top clamping mechanism based on an angle-adjustable guide post. Background Technology

[0002] In the field of machining, especially in the processing of easily deformable workpieces such as thin-walled parts and irregular-shaped parts, the side-top clamping mechanism is a key tooling component to ensure the stability of workpiece positioning and machining accuracy. Its main function is to apply clamping force to the side of the workpiece and, in conjunction with other positioning structures, reliably fix the workpiece and avoid dimensional deviations caused by workpiece displacement during the machining process.

[0003] Currently, side-top clamping mechanisms on the market generally have structural design defects: most traditional side-top clamps do not have a dedicated guide structure. During the process of the side-top block applying side-top force to the workpiece, the side-top block is easily affected by the reaction force of the workpiece or the assembly gap, causing it to shift left and right or float up and down. This floating phenomenon will directly cause the direction of the side-top force to deviate from the preset positioning direction, which in turn causes the part to be subjected to an upward component force, causing the part to float up.

[0004] The floating of parts not only destroys the initial positioning datum of the workpiece, causing a significant decrease in positioning accuracy, but also leads to an increase in the relative positional deviation between the tool and the workpiece in subsequent machining processes, resulting in problems such as out-of-tolerance machining dimensions and unqualified surface roughness. In severe cases, it may even cause a tool collision accident due to workpiece positioning failure, resulting in workpiece scrap or equipment damage. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a side-top clamping mechanism based on an angle-adjustable guide post with side-top guidance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This utility model is further configured as follows: it includes a positioning part, and the side-top clamping mechanism based on the angle-adjustable guide column also includes an adjusting abutment unit; the adjusting abutment unit is disposed on the positioning part; the adjusting abutment unit includes a first sliding part, a guide part, and a contact part; the first sliding part is slidably disposed on the positioning part in the vertical direction; the guide part is slidably disposed on the positioning part in the horizontal direction, and the positioning part has a horizontal displacement chamber for the guide part to slide, so that when the first sliding part descends, it can drive the guide part to move in the horizontal direction; the contact part is rotatably disposed on the end face of the guide part, and the end face of the guide part has a circular opening for installing the contact part, so that when the guide part moves, it can drive the contact part to abut against the contact surface of the workpiece; the top of the positioning part has a positioning through hole for a positioning pin to pass through.

[0007] By adopting the above technical solution, the problem of insufficient flexibility in adjusting the position of the positioning part in real time according to the actual machining direction of the workpiece after it is installed on the machine tool by the positioning pin is solved, as well as the problem of the side top block of the traditional side top clamp being prone to floating left and right, up and down due to the lack of a guide structure, which in turn causes the part to float upward due to the upward component force. It achieves the effect of effectively preventing the workpiece from floating on the clamping surface, while ensuring the side top clamping accuracy and the workpiece fixing reliability.

[0008] The present invention is further configured such that: the adjusting abutment unit also includes an inclined pressure block; the inclined pressure block is slidably disposed on the positioning part in the vertical direction, and the top of the positioning part is provided with a stroke chamber for the inclined pressure block to slide, and the top of the inclined pressure block is provided with a circular hole for installing the first sliding part.

[0009] The present invention is further configured such that: the adjusting abutment unit also includes a first buffer part; the first buffer part has a pair and is respectively disposed on the positioning part, and the top of the positioning part is provided with an installation chamber for installing the pair of first buffer parts, and when the first sliding part and the inclined pressure block descend, the pair of first buffer parts are both in a compressed state.

[0010] The present invention is further configured such that: the adjusting abutment unit also includes a side top block; the side top block is slidably disposed on the side of the positioning part, and a horizontal cavity for installing and restricting the sliding of the side top block is provided on the side of the positioning part, so that when the inclined pressure block moves, it can contact the end face of the side top block and drive the side top block to move.

[0011] The present invention is further configured such that: the adjusting abutment unit also includes a second buffer part; the second buffer part is disposed on the positioning part, and a circular cavity for installing the second buffer part is provided on the inner side of the positioning part, so that when the side top block moves, it can abut against the second buffer part and drive the second buffer part into a compressed state.

[0012] The present invention is further configured such that: a circular groove is provided in the middle of the side top block for the guide part to abut against, and when the side top block moves, the side top block can push the guide part to move synchronously.

[0013] The present invention is further characterized in that the end face of the contact portion has a chamfered structure.

[0014] In summary, this application includes at least one of the following beneficial technical effects: By incorporating an adjustable abutment unit, the problem of insufficient flexibility in real-time adjustment of the positioning unit's position according to the actual machining direction of the workpiece after it is installed on the machine tool via positioning pins is solved. Furthermore, the traditional side-top clamping fixture, lacking a guiding structure, causes the side-top block to easily float left and right, up and down, resulting in the workpiece being lifted by an upward force. This effectively prevents the workpiece from floating on the clamping surface while ensuring both the side-top clamping accuracy and the reliability of workpiece fixation.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] Please see Figure 1-4 The present invention provides the following technical solution: Example 1: In order to solve the problem that traditional side-top components, commonly used side-top clamps do not have guides, and when the side-top is in operation, the side-top block 241 floats left and right and up and down, which easily causes the part to float up due to the upward component force.

[0019] The side-top clamping mechanism based on the angle-adjustable guide post, including the positioning part 1, also includes an adjusting abutment unit 2. The adjusting abutment unit 2 is disposed on the positioning part 1. The adjusting abutment unit 2 includes a first sliding part 21, a guide part 22, and a contact part 221. The first sliding part 21 is slidably disposed on the positioning part 1 in the vertical direction. The guide part 22 is slidably disposed on the positioning part 1 in the horizontal direction, and the positioning part 1 has a horizontal displacement chamber for the guide part 22 to slide. When the first sliding part 21 descends, it can drive the guide part 22 to move in the horizontal direction. The contact part 221 is rotatably disposed on the end face of the guide part 22, and the end face of the guide part 22 has a circular opening for mounting the contact part 221. When the guide part 22 moves, it can drive the contact part 221 to abut against the contact surface of the workpiece. The top of the positioning part 1 has a positioning through hole 11 for passing a positioning pin.

[0020] In this embodiment, the top of the positioning part 1 is provided with a positioning through hole 11, and the operator can use the positioning pin to install the positioning part 1 onto the machine tool. After installation, the operator can adjust the position of the positioning part 1 in real time according to the actual processing direction of the workpiece.

[0021] In this embodiment, the contact portion 221 is preferably a spherical ball, and the contact portion 221 can rotate within a range of ±9° within the circular opening on the end face of the guide portion 22. When the contact portion 221 is in contact with the workpiece surface, the contact portion 221 can adjust its angle to adapt to the workpiece surface based on the side contact surface when it is clamped against the side of the workpiece. This allows the guide portion 22 and the contact portion 221 to flexibly adjust their contact positions with the surface of the workpiece being clamped in different side clamping scenarios to meet the clamping and positioning requirements of workpieces of different shapes and positions.

[0022] When a workpiece needs to be side-clamped, this embodiment can use a cylinder to push the first sliding part 21, causing the guide part 22 and the contact part 221 to move until the contact part 221 applies a stable clamping force to the side of the workpiece, thus fixing the workpiece. This effectively prevents the clamped surface of the workpiece from floating due to the upward component force. It solves the problem of insufficient flexibility in adjusting the position of the positioning part 1 in real time according to the actual machining direction of the workpiece after it is installed on the machine tool by the positioning pin, and the problem of traditional side-clamping fixtures causing the side top block 241 to float left and right or up and down due to the lack of a guide structure, which in turn causes the part to float due to the upward component force. It achieves the effect of effectively preventing the clamped surface of the workpiece from floating, while ensuring the side-clamping accuracy and the reliability of workpiece fixation.

[0023] See Figure 3 and Figure 4 The adjusting abutment unit 2 also includes an inclined pressure block 23; the inclined pressure block 23 is slidably disposed on the positioning part 1 in the vertical direction, and the top of the positioning part 1 is provided with a stroke chamber for the inclined pressure block 23 to slide, and the top of the inclined pressure block 23 is provided with a circular hole for installing the first sliding part 21.

[0024] In this embodiment, when the first sliding part 21 slides, it can come into contact with the travel chamber in the middle of the inclined pressure block 23, and drive the inclined pressure block 23 to move synchronously in the vertical direction.

[0025] See Figure 3 and Figure 4 The adjusting abutment unit 2 also includes a first buffer part 24; the first buffer part 24 has a pair and is respectively disposed on the positioning part 1, and the top of the positioning part 1 is provided with an installation chamber for installing the pair of first buffer parts 24. When the first sliding part 21 and the inclined pressure block 23 descend, the pair of first buffer parts 24 are both in a compressed state.

[0026] When the first sliding part 21 and the inclined pressure block 23 descend, they can drive a pair of first buffer parts 24 mounted on the positioning part 1 in the mounting cavity to be compressed. In this embodiment, the second buffer part 25 is preferably a return spring.

[0027] See Figure 3 and Figure 4 The adjusting abutment unit 2 also includes a side top block 241; the side top block 241 is slidably disposed on the side of the positioning part 1, and a horizontal cavity for installing and restricting the sliding of the side top block 241 is provided on the side of the positioning part 1. When the inclined pressure block 23 moves, it can contact the end face of the side top block 241 and drive the side top block 241 to move.

[0028] In this embodiment, when the first sliding part 21 and the inclined pressure block 23 move, in this state, the inclined pressure block 23 can contact the inclined surface of the side top block 241 and drive the side top block 241 to move along the horizontal cavity opened on the mounting part.

[0029] See Figure 3 and Figure 4 The adjusting abutment unit 2 also includes a second buffer part 25; the second buffer part 25 is disposed on the positioning part 1, and a circular cavity for installing the second buffer part 25 is provided on the inner side of the positioning part 1. When the side top block 241 moves, it can abut against the second buffer part 25 and drive the second buffer part 25 into a compressed state.

[0030] When the side top block 241 moves, it can drive the second buffer part 25 into a compressed state. When the side top moves, it can drive the guide part 22, which abuts against the side top block 241, into a clamping abutment state against the side of the workpiece. In this embodiment, the second buffer part 25 is preferably a return spring.

[0031] See Figure 3 The side top block 241 has a circular groove in the middle for the guide part 22 to abut. When the side top block 241 moves, the side top block 241 can push the guide part 22 to move synchronously.

[0032] In this embodiment, when the side top block 241 moves, it can drive the second buffer part 25 into a compressed state. The side of the guide part 22 can abut against the circular groove opened in the middle of the side top block 241, thereby driving the guide part 22 to move when the side top block 241 moves, realizing the clamping and abutment of the workpiece by the guide part 22, ensuring the movement restriction of the guide part 22, and ensuring the stable guidance of the guide part 22.

[0033] See Figure 3 The end face of the contact part 221 has a chamfered structure.

[0034] In this embodiment, in order to reduce contact damage to the workpiece, the end face of the contact portion 221 is a chamfered structure, which can stably clamp the workpiece while reducing contact damage to the workpiece clamping contact surface.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
