Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a pad for machining. Background Technology

[0002] In the field of machining, spacers are indispensable auxiliary tools widely used in many operations such as machine tool processing, mold assembly, and mechanical parts assembly. Taking precision machine tool processing as an example, when machining high-precision mechanical components, it is necessary to accurately position the mechanical components at a specific height and angle. At this time, spacers play a crucial role in adjusting the height of the workpiece and calibrating its horizontal position, ensuring that the machining tool can accurately cut the mechanical component according to the predetermined trajectory. In the process of assembling automotive molds, when splicing the various parts of a large mold, spacers are used to support and adjust the relative positions between the parts, ensuring the mold closing accuracy and avoiding quality problems such as flash and dimensional discrepancies in injection molded products due to positional deviations.

[0003] However, traditional machining pads have revealed many drawbacks in practical applications. Firstly, their structure is simple and fixed, mostly consisting of standard block or plate-shaped parts. Their height and support point positions cannot be flexibly adjusted according to the specific shape and size requirements of the workpiece. When machining irregularly shaped workpieces, standard pads struggle to conform to the workpiece's contour, often requiring manual addition of pads or cutting modifications, which is cumbersome and difficult to guarantee accuracy. Secondly, their positioning methods are rudimentary. Most pads rely solely on friction between themselves and the worktable or simple bolt fixation. Under the vibrations generated by high-speed machine tool operation or the large external forces applied during mold assembly, they are prone to displacement or loosening, leading to workpiece position deviation. This not only reduces the yield rate but may also cause tool damage, mold collisions, and other equipment malfunctions. Furthermore, existing pads lack effective adjustment mechanisms when facing multi-point support requirements under complex working conditions, making it difficult to achieve uniform force support for the workpiece, further limiting their application in high-precision machining.

[0004] Therefore, in response to the urgent need for flexibility, stability and adaptability of pads in current machining processes, developing a new type of machining pad that can flexibly adjust the height and support position, provide stable and reliable positioning, and is suitable for complex working conditions has become the key to improving machining efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to provide a machining pad to solve the problems of existing machining pads mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a machining pad, comprising:

[0007] The base has inclined grooves on both sides, and several sets of adjusting lock holes are equally spaced on the inner wall of both sides of the inclined grooves.

[0008] Two sets of sliding tables are movably connected to the two sets of inclined slots respectively. The sliding tables have an inner groove inside. The two sets of sliding tables have a paddle slot on the side away from each other. The sliding tables also have positioning slots on the front and rear sides. Two sets of connecting frames are movably installed in the inner groove. A locking rod is fixedly connected to the end of the two sets of connecting frames away from each other. The locking rod is inserted into the positioning slot. A control paddle is fixedly connected to the side of the connecting frame near the paddle slot. The control paddle moves in the paddle slot. The positioning slot, the paddle slot and the inner groove are connected. The upper end of the sliding table has a plate-shaped groove that runs horizontally through it.

[0009] The top frame is connected to the two sets of plate-shaped grooves.

[0010] Preferably, the bottom of the slide table and the inner bottom surface of the inclined groove are inclined surfaces that are adapted to each other, and the slide table moves along the inclined surface of the inclined groove so that the positioning groove corresponds to the position of the adjusting lock hole.

[0011] Preferably, a return spring is provided in the inner groove, and the return spring is fixedly connected between the two sets of connecting frames.

[0012] Preferably, the end of the locking rod away from the connecting frame passes through the positioning groove and connects to the adjusting lock hole, and the height and width of the locking rod, the height and width of the positioning groove, and the height and width of the adjusting lock hole are respectively adapted to each other.

[0013] Preferably, the height and width of the top frame are adapted to the height and width of the plate-shaped groove, and half of the length of the top frame is greater than the length of the plate-shaped groove.

[0014] Preferably, the top frame is provided with a multi-point support mechanism, the multi-point support mechanism comprising:

[0015] Several sets of internal threaded adjustment holes are opened in a regular matrix within the top frame;

[0016] Several sets of auxiliary pads are connected to the top frame through the internal threaded adjustment holes.

[0017] Preferably, the auxiliary pad includes:

[0018] The lower part of the thread is connected to the internal thread adjustment hole through a threaded structure.

[0019] The upper part is supported and fixedly connected to the top of the lower part of the thread;

[0020] Specifically, the lower part of the thread is rotated so that the top surface of the upper support is on the same horizontal plane as the top surface of the slide.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1) The inclined grooves and slides on both sides of the base of this application adopt a sliding structure with inclined surface cooperation. Utilizing the principle of inclined surface transmission, the user only needs to push the slide along the inclined surface of the groove to make the slide move smoothly between different height positions. When the slide moves to the appropriate position, the positioning groove in the slide can accurately align with the adjustment lock hole on the inner wall of the inclined groove of the base. Pushing the locking rod into the adjustment lock hole can quickly lock the position of the slide. This adjustment method is not only easy to operate, but also can be freely switched between multiple preset height positions. It can quickly adapt to the processing needs of various specifications of workpieces, from small electronic components to large mechanical parts. It changes the inefficient operation mode of frequent replacement of traditional pads and significantly improves the production efficiency of machining.

[0023] 2) Regarding positioning stability, this application employs a dual-stabilized locking system for the pad block. On one hand, the inclined surface design of the slide bottom, which is adapted to the inner bottom surface of the inclined groove, allows the slide to generate a component force along the inclined direction under the action of gravity and workpiece pressure, tightly fitting the slide against the inner wall of the inclined groove, forming a natural anti-displacement structure. On the other hand, the mechanical locking mechanism composed of the connecting frame, locking rod, and control lever, after the slide is adjusted to the correct position, can withstand the high-frequency vibration during machine tool processing and the large external force during mold assembly through the tight cooperation between the locking rod and the adjusting locking hole, effectively preventing the slide from loosening or shifting. Thus, it provides a solid and reliable support foundation for the workpiece, ensuring that the workpiece always maintains accurate positioning during processing, greatly improving processing accuracy, and reducing processing errors and scrap rates caused by unstable positioning.

[0024] 3) This application further expands the application scenarios and support performance of the pads through a multi-point support mechanism. Users can flexibly adjust the position and height of each auxiliary pad according to the shape characteristics and stress distribution of the workpiece. For irregularly shaped workpieces, the top surface of the auxiliary pads at specific positions can be perfectly fitted with the contour of the workpiece by raising or lowering them, thus achieving multi-point uniform support. Under processing conditions with concentrated loads, the support strength of the auxiliary pads at key stress points can be enhanced, effectively dispersing the weight of the workpiece and the impact force generated during processing, and avoiding workpiece deformation or damage due to excessive local stress. Thus, it not only improves the adaptability of the pads to complex-shaped workpieces, but also provides reliable technical support for high-end precision machining. Attached Figure Description

[0038] Please see Figure 1-8 This utility model provides a technical solution: a machining pad, comprising:

[0039] The base 1 has inclined grooves 2 on both sides, and several sets of adjusting lock holes 10 are equally spaced on the inner wall of both sides of the inclined grooves 2.

[0040] Two sets of slides 3 are movably connected to two sets of inclined grooves 2 respectively. The slides 3 have an inner groove 4. The two sets of slides 3 have a paddle groove 5 on the side away from each other. The slides 3 also have positioning grooves 6 on both the front and rear sides. Two sets of connecting frames 7 are movably installed in the inner groove 4. The two sets of connecting frames 7 are fixedly connected to a locking rod 8 at the end away from each other. The locking rod 8 is inserted into the positioning groove 6. The connecting frame 7 is fixedly connected to a control paddle 9 on the side near the paddle groove 5. The control paddle 9 moves in the paddle groove 5. The positioning groove 6, the paddle groove 5 and the inner groove 4 are connected. The upper end of the slides 3 has a plate-shaped groove 13 that runs horizontally through it.

[0041] The top frame 12 is connected to two sets of plate-shaped grooves 13.

[0042] Specifically, inclined grooves 2 are provided on both sides of the base 1, providing an adjustable moving track for the slide table 3. The inner groove 4, the lever groove 5, and the positioning groove 6 inside the slide table 3, together with the connecting frame 7, the locking rod 8, and the control lever 9, form a complete adjustment and positioning system. The top frame 12 is connected to the plate-shaped groove 13 of the slide table 3. This overall structural design enables the pad to achieve multi-dimensional adjustment and positioning functions. The cooperation between the base 1 and the slide table 3 allows the position of the slide table 3 in the inclined groove 2 to be adjusted according to the height requirements of different workpieces, adapting to various processing scenarios. The locking mechanism composed of the connecting frame 7, the locking rod 8, and the control lever 9 can precisely lock the position of the slide table 3 by operating the control lever 9 after the slide table 3 is adjusted to the correct position, ensuring the stability of the pad during processing and avoiding processing errors caused by displacement. The top frame 12 provides a stable bearing platform for the workpiece, working in conjunction with the slide table 3 to improve the pad's support capacity for workpieces of different shapes and sizes.

[0043] Specifically, the height of the control lever 9 is adapted to the height of the lever slot 5. The lever slot 5 has a positioning function for the control lever 9, and one end of the control lever 9 extends out of the outside of the lever slot 5, which makes it convenient for the operator to operate the control lever 9 from the outside of the slide table 3.

[0044] Reference manual attached Figure 2-3 and instruction manual attached Figure 6-7 The bottom of the slide table 3 and the inner bottom surface of the inclined groove 2 are inclined surfaces that are compatible with each other. The slide table 3 moves along the inclined surface of the inclined groove 2 so that the positioning groove 6 corresponds to the position of the adjusting lock hole 10. Specifically, when the slide table 3 moves along the inclined surface of the inclined groove 2, the mechanical principle of the inclined surface is used to not only easily adjust the height, but also maintain stability during the movement. Moreover, by moving the slide table 3 to make the positioning groove 6 correspond to the position of the adjusting lock hole 10, an accurate interface is provided for the subsequent locking of the locking rod 8, ensuring that the position of the slide table 3 can be firmly fixed after adjustment. By pushing the locking rod 8 into the adjusting lock hole 10, the position of the slide table 3 can be quickly locked. This adjustment method is not only easy to operate, but also can be freely switched between multiple preset height positions. It can quickly adapt to the processing needs of various specifications of workpieces, from small electronic components to large mechanical parts, changing the inefficient operation mode of frequent replacement of traditional pads and significantly improving the production efficiency of machining.

[0045] Reference manual attached Figure 4 A return spring 11 is provided in the inner groove 4, and the return spring 11 is fixedly connected between the two sets of connecting brackets 7. Specifically, the return spring 11 provides an automatic reset function for the movement of the connecting brackets 7 and the locking rod 8. When adjusting the position of the slide 3, pushing the control lever 9 inward causes the locking rod 8 to retract against the elastic force of the return spring 11, pulling the locking rod 8 out of the adjusting lock hole 10, facilitating the movement of the slide 3; when the slide 3 moves to the appropriate position, releasing the control lever 9 causes the return spring 11 to push the connecting bracket 7, thereby automatically inserting the locking rod 8 into the adjusting lock hole 10 to complete the locking. This automatic reset mechanism simplifies the operation process, reduces manual operation steps, improves adjustment efficiency, and also ensures a tight fit between the locking rod 8 and the adjusting lock hole 10, enhancing the positioning stability of the pad.

[0046] Reference manual attached Figure 4The end of the locking rod 8 furthest from the connecting frame 7 passes through the positioning groove 6 and connects to the adjusting locking hole 10. The height and width of the locking rod 8, the height and width of the positioning groove 6, and the height and width of the adjusting locking hole 10 are respectively matched. Specifically, this precise dimensional matching design ensures that the locking rod 8 can form a tight fit after being inserted into the adjusting locking hole 10, providing a strong locking force. During the processing, even if affected by factors such as machine tool vibration and external impact, the locking rod 8 can firmly fix the position of the slide table 3, preventing the slide table 3 from shifting. This ensures the accurate positioning of the workpiece during the processing, effectively improves processing accuracy, reduces the scrap rate, and provides a reliable guarantee for machining.

[0047] Specifically, in terms of positioning stability, this application employs a dual-stabilized locking system for the pad block. On one hand, the inclined surface design of the bottom of the slide table 3, which is adapted to the inner bottom surface of the inclined groove 2, allows the slide table to generate a component force along the inclined surface under the action of gravity and workpiece pressure, tightly fitting the slide table against the inner wall of the inclined groove, forming a natural anti-displacement structure. On the other hand, the mechanical locking mechanism composed of the connecting frame 7, locking rod 8, and control lever 9, after the slide table 3 is adjusted into position, can withstand the high-frequency vibration during machine tool processing and the large external force during mold assembly through the tight cooperation between the locking rod 8 and the adjusting lock hole 10, effectively preventing the slide table 3 from loosening or displacing. Thus, it provides a solid and reliable support foundation for the workpiece, ensuring that the workpiece always maintains accurate positioning during processing, greatly improving processing accuracy, and reducing processing errors and scrap rates caused by unstable positioning.

[0048] Reference manual attached Figure 1 and instruction manual attached Figure 3 The height and width of the top frame 12 are matched with the height and width of the plate-shaped groove 13, and half the length of the top frame 12 is greater than the length of the plate-shaped groove 13. Specifically, this allows the top frame 12 to be stably installed in the plate-shaped groove 13 of the slide table 3, while its longer length forms a stable support structure on the slide table 3, and the top frame 12 can always be fully connected in both sets of plate-shaped grooves 13. When carrying a workpiece, the top frame 12 can evenly distribute the weight of the workpiece and the force during the processing, avoiding deformation or instability of the slide table 3 due to excessive local force. Moreover, the close fit between the top frame 12 and the slide table 3 further enhances the structural strength and stability of the entire pad, enabling it to adapt to various complex processing conditions and providing a reliable and larger support platform for the workpiece.

[0049] Reference manual attached Figure 1 and instruction manual attached Figure 8 The top frame 12 is equipped with a multi-point support mechanism, which includes:

[0050] Several sets of internal threaded adjustment holes 14 are opened in a regular matrix inside the top frame 12;

[0051] Several sets of auxiliary pads 15 are connected to the top frame 12 through internal threaded adjustment holes 14.

[0052] Specifically, the multi-point support mechanism greatly enhances the adaptability of the pads to workpieces of different shapes. In actual processing, for workpieces with irregular shapes and uneven surfaces, the height of the auxiliary pads 15 at different positions can be adjusted to ensure their top surfaces are in contact with the workpiece surface, achieving uniform multi-point support. This multi-point support method effectively distributes the weight of the workpiece and the stress during processing, preventing deformation of the workpiece due to uneven local stress and improving processing quality. Furthermore, users can flexibly adjust the distribution and height of the auxiliary pads 15 according to the specific shape and stress conditions of the workpiece, enabling the pads to meet diverse processing needs and broadening their application range.

[0053] Reference manual attached Figure 5 The auxiliary pad 15 includes:

[0054] The lower thread 1501 is connected to the internal thread adjustment hole 14 through a threaded structure;

[0055] The upper support 1502 is fixedly connected to the top of the threaded lower part 1501;

[0056] The lower thread 1501 is rotated so that the top surface of the upper support 1502 is on the same horizontal plane as the top surface of the slide 3.

[0057] Specifically, this design allows for easy height adjustment of the auxiliary pad 15, which, after adjustment, forms a flat support surface together with the slide table 3. During processing, the user can precisely adjust the height of the auxiliary pad 15 according to the actual condition of the workpiece, ensuring effective support. Simultaneously, the design of a single horizontal plane ensures the stability of the workpiece on the support surface, preventing tilting or uneven stress due to height differences, thereby improving processing accuracy and product quality.

[0058] Reference manual attached Figure 6 The positioning groove 6 on the slide table 3 corresponds to the position of the adjustment lock hole 10 at the lowest horizontal position. At this time, the control lock rod 8 passes through the positioning groove 6 and connects to the corresponding adjustment lock hole 10, thereby fixing the slide table 3 at the lowest position of the base 1; refer to the attached instruction manual. Figure 7 After the two sets of slide tables 3 are adjusted by sliding them obliquely upwards, the positioning groove 6 on the slide table 3 corresponds to the position of the adjustment lock hole 10 located in the middle of the horizontal position. At this time, the control lock rod 8 passes through the positioning groove 6 and connects to the corresponding adjustment lock hole 10, thereby fixing the slide table 3 in the middle position of the base 1.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
