Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a machining fixture for arc-shaped grooves and arc-shaped surface parts. Background Technology

[0002] Many metal parts are roughed and finished by machine tools. In order to facilitate the stable processing of parts, fixtures or tooling need to be set on the machine tool worktable to fix the parts to be processed. For parts with relatively regular shapes and structures, it is relatively easy to clamp and fix them. However, some parts with complex structures and irregular shapes are not easy to install and fix.

[0003] As per the instruction manual Figure 1 and 2 As shown, this is a base-type component with large countersunk holes on both the upper and lower surfaces, beveled sides, an arc surface on one side, and a flat surface on only one side. This type of component needs to be machined to create the arc groove on its upper surface and then precision machined to its arc surface. Existing tooling fixtures are not easy to fix it, and there are some fixing methods that can fix it, but the tooling and operation methods used are more complicated. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a machining fixture for arc-shaped grooves and arc-shaped surface parts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A machining fixture for arc-shaped grooves and arc-shaped surface parts includes a fixture base, a support key block on the fixture base, a limiting slider slidably connected above the support key block, the width of the limiting slider in the sliding direction being smaller than the width of the support key block, side plates connected to both sides of the limiting slider in the length direction, the side plates abutting against the sidewall of the support key block; a baffle plate is also connected to one side of the support key block in the width direction, the baffle plate is provided with a locking bolt, the locking bolt passing through the baffle plate and abutting against the limiting slider; the fixture base is also provided with a limiting shaft hole, the limiting shaft hole being arranged away from the side where the baffle plate is located.

[0007] This machining fixture has a simple structure and is easy to install and use. With the setting of the limiting slider and the limiting shaft hole, the parts to be processed placed on the fixture base can be positioned and fixed in a relatively convenient way, which is beneficial for machining the arc grooves of the parts to be processed and for finishing the outer contour.

[0008] Furthermore, it also includes a stepped limiting shaft that mates with the limiting shaft hole. One end of the stepped limiting shaft is connected to the limiting shaft hole, and the other end is used to connect the part to be processed. One side of the part to be processed abuts against the limiting slider and the side plate. The stepped limiting shaft allows for convenient connection of the part to be processed. Combined with the lateral limiting of the limiting slider and the side plate, the part to be processed can be easily fixed without the need for complex clamping devices, effectively securing such irregular parts.

[0009] Furthermore, the support key block is provided with a limiting post, and the limiting slider is provided with a strip hole. The length direction of the strip hole is arranged along the sliding direction, and the limiting post is connected in the strip hole, so that the limiting slider can slide within the length range of the strip hole.

[0010] Furthermore, the limiting slider and the pair of side plates are flush with the side facing the side where the limiting shaft hole is located, and the bottom of the side plates is supported on the tooling base.

[0011] Furthermore, the upper surface of the tooling base is provided with a shallow groove, which is conducive to the discharge of machining waste and coolant falling from above, allowing the waste and coolant to flow out of the tooling base in a timely manner, and preventing the waste and coolant from accumulating in the machining area.

[0012] Furthermore, the support key block is centrally arranged in the width direction of the tooling base, and the tooling base is also provided with a base mounting hole in the middle, and the center axis of the base mounting hole and the limiting shaft hole are located on the same vertical section.

[0013] Furthermore, two support key blocks are symmetrically arranged on the tooling base, and correspondingly, there are two sets of the limiting slider, the baffle and the locking bolt, and two limiting shaft holes are also symmetrically arranged.

[0014] Furthermore, the support key block, the limiting slider, the baffle, and the side plate are all metal structural components. The support key block is connected to the tooling base by countersunk bolts, and the baffle is connected to the support key block and the side plate is connected to the limiting slider by bolts.

[0015] Furthermore, the tooling base has a cavity, and the cavity has several reinforcing ribs arranged in an alternating pattern.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This machining fixture has a simple structure, is easy to install and use. Through the setting of the limiting slider and the limiting shaft hole, the workpiece to be processed placed on the fixture base can be positioned and fixed in a relatively convenient way, which is beneficial for machining the arc groove of the workpiece and the fine machining of the outer peripheral contour; 2. The combination of the supporting key block and the limiting slider can form a limiting structure that moves horizontally relative to the fixture base on the fixture base. The limiting slider can limit the workpiece to be processed arranged on one side, and can also appropriately adjust the horizontal position to limit the workpiece of this type with various models and sizes; 3. The side plate is connected to the limiting... The combination of the two sides of the limiting slider can improve the movement stability and directionality of the limiting slider, and also increase the support area of ​​the side of the limiting slider. The two together abut against the workpiece to be processed, forming a larger area of ​​lateral support and limiting; 4. The locking bolt can abut against the limiting slider to lock the limiting slider and prevent it from moving, thereby completing the limiting and fixing of the workpiece to be processed; 5. The stepped limiting shaft can easily connect the workpiece to be processed. With the limiting slider and the side limiting of the side plate, the workpiece to be processed can be simply fixed. It can effectively fix such irregular parts without setting up a complicated clamping device, and can also fully expose the surface to be processed. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "middle," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] like Figures 3-7 As shown, a machining fixture for arc-shaped grooves and arc-shaped surface parts includes a fixture base 2, on which a support key block 3 is provided. A limiting slider 4 is slidably connected above the support key block 3. The width of the limiting slider 4 in the sliding direction is smaller than the width of the support key block 3. Side plates 5 are respectively connected to both sides of the limiting slider 4 in the length direction, and the side plates 5 abut against the side wall of the support key block 3. A baffle 6 is also connected to one side of the support key block 3 in the width direction. A locking bolt 7 is provided on the baffle 6. The locking bolt 7 passes through the baffle 6 and abuts against the limiting slider 4. The fixture base 2 is also provided with a limiting shaft hole 8, which is arranged away from the side where the baffle 6 is located.

[0031] This machining fixture has a simple structure and is easy to install and use. With the setting of the limiting slider 4 and the limiting shaft hole 8, the part to be processed 1 placed on the fixture base 2 can be positioned and fixed in a relatively convenient way, which is beneficial for machining the arc groove of the part to be processed and for finishing the outer contour.

[0032] The combination of the support key block 3 and the limiting slider 4 can form a limiting structure on the tooling base that moves horizontally relative to the tooling base. The limiting slider 4 can be used to limit the parts to be processed arranged on one side, and the horizontal position can also be adjusted appropriately to limit the parts of this type with various sizes.

[0033] The side plate 5 is connected to both sides of the limiting slider 4. On the one hand, the two can form a U-shaped sliding structure that is inverted on the support key block 3, which improves the movement stability and directionality of the limiting slider 4, and prevents the limiting slider 4 from sliding in other directions in the horizontal plane, which is beneficial to improving the accuracy of subsequent processing. On the other hand, the side plate 5 can increase the support area of ​​the side of the limiting slider. The two together abut against the parts to be processed, forming a larger area of ​​lateral support and limiting.

[0034] The baffle 6 is provided so that the locking bolt 7 can be connected to it. The locking bolt 7 can abut against the limiting slider 4 to lock the limiting slider 4 and prevent it from moving, thereby completing the limiting and fixing of the parts to be processed.

[0035] Furthermore, the machining fixture also includes a stepped limiting shaft 14 that mates with the limiting shaft hole 8. One end of the stepped limiting shaft 14 is connected to the limiting shaft hole 8, and the other end is used to connect to the part 1 to be processed. One side of the part 1 to be processed abuts against the limiting slider 4 and the side plate 5 (see [reference]). Figure 10 (As shown).

[0036] The stepped limiting shaft 14 can be used to easily connect the parts to be processed. With the side limiting of the limiting slider 4 and the side plate 5, the parts to be processed can be easily fixed without the need for a complicated clamping device. This method of limiting and fixing can effectively fix such irregular parts. The upper surface of the parts to be processed can be completely exposed. The arc groove to be processed is concentric with the rotation circle of the tooling base, which can be easily milled. The arc contour surface of the outer periphery is also unobstructed, which makes it convenient for the tool to perform fine machining on the outer periphery and control its dimensional accuracy.

[0037] Furthermore, the support key block 3 is provided with a limiting post 10, and the limiting slider 4 is provided with a strip hole 9 that runs vertically through the slider. The length direction of the strip hole 9 is arranged along the sliding direction, and the limiting post 10 is connected to the strip hole 9.

[0038] The cooperation between the limiting post 10 and the strip hole 9 allows the limiting slider 4 to slide within the length range of the strip hole 9. The limiting post 10 serves to limit and guide the movement, and also prevents the limiting slider from wobbling in the width direction of the support base. The limiting post 10 can be a connecting rod connected to the support key block 4.

[0039] Furthermore, the limiting slider 4 and the pair of side plates 5 are flush with each other on the side facing the limiting shaft hole. The bottom of the side plate 5 is supported on the tooling base 2, so that the side plate 5 can also provide vertical support for the limiting slider. The side plate 5 can slide relative to the tooling base and the support key block.

[0040] Furthermore, the upper surface of the tooling base 2 is also provided with a shallow groove 11. The shallow groove 11 is located in the area where the parts to be processed are placed. The shallow groove 11 extends from near the support key block to the edge of the tooling base. This shallow groove 11 is conducive to the discharge of processing waste and coolant falling from above, allowing the waste and coolant to flow out of the tooling base in a timely manner, and preventing the waste and coolant from accumulating in the processing area.

[0041] The shallow groove 11 can be set with a certain slope (such as a slope of no more than 3°) and is arranged inclined from the side near the support key block toward the edge of the tooling base, which is conducive to chip and liquid discharge.

[0042] Furthermore, the support key block 3 is centrally arranged in the width direction of the tooling base 2, and the tooling base 2 is also provided with a base mounting hole 12 in the middle. The base mounting hole 12 and the central axis of the limiting shaft hole 8 are located on the same vertical section.

[0043] The base mounting hole 12 can be connected to the machine tool worktable. The base mounting hole 12 is located at the exact center of the entire tooling base, and the line connecting it to the limiting shaft hole 8 is approximately equal to the radius of the arc groove to be processed. This arrangement is beneficial for alignment and processing. In the actual processing, the tooling base can be fixed, and the tool can rotate around the central axis of the base mounting hole to process the arc groove and the outer arc surface. Alternatively, the tooling base can rotate around the base mounting hole as the central axis, which also facilitates the processing of the arc groove and the arc surface.

[0044] Furthermore, two support key blocks 3 are symmetrically arranged on the tooling base 2, and correspondingly, there are two sets of limiting sliders 4, baffles 6 and locking bolts 7, and two limiting shaft holes 8 are also symmetrically arranged.

[0045] By symmetrically arranging two sets of these limiting structures with the mounting hole 12 of the base as the center, two parts to be processed can be installed at the same time, and the two parts to be processed can be processed at the same time. This can not only improve the processing efficiency, but also make full use of its rotary processing characteristics.

[0046] Furthermore, the supporting key block 3, the limiting slider 4, the baffle 6, and the side plate 5 are all independent metal structural parts that can be manufactured separately and then assembled as needed. These metal structures are all relatively simple, basically cuboid structures, and only threaded holes need to be set where connections are required. They are very easy to manufacture, install, and use. Moreover, various sizes can be selected and combined according to actual conditions to complete the limiting and fixing of more such parts to be processed.

[0047] The support key block 3 is connected to the tooling base 2 via countersunk bolts. The baffle 6 is connected to the support key block 3, and the side plate 5 is connected to the limiting slider 4 via bolts. This connection and installation method requires only a few threaded holes to be drilled on the tooling base to complete the assembly, thus better maintaining the structural integrity of the tooling base and reducing the number of holes and slots required and the workload.

[0048] Furthermore, the tooling base 2 has a cavity, and the cavity contains a plurality of staggered reinforcing ribs 13. The cavity reduces the weight of the tooling base 2 and lightens its load, while the reinforcing ribs 13 enhance its strength and stability.

[0049] For the rectangular tooling base 2, there are multiple partitions at the bottom, which divide the space into multiple small spaces. Each small space is provided with diagonally intersecting reinforcing ribs 13. At the intersection of the reinforcing ribs, there are column structures. These column structures correspond exactly to the base mounting hole 12 and the limiting shaft hole 8. This arrangement can ensure the integrity and strength of the base mounting hole and the limiting shaft hole, so that they can better bear the force.

[0050] Combination Figure 10 As shown, one way to use this machining fixture is as follows: Insert one end of the stepped limiting shaft 14 into the limiting shaft hole 8, then place the workpiece 1 to be processed in the machining area, so that the connecting hole at its bottom is connected to the stepped limiting shaft 14; then adjust the limiting slider 4 horizontally so that the limiting slider 4 and the side plate 5 abut against the side wall of the workpiece 1 with a flat surface. After abutting, tighten the locking bolt 7, which abuts against the limiting slider 4 and fixes the limiting slider 4, thus completing the installation and fixing of the workpiece 1; similarly, install another workpiece 1 to be processed in the machining area on the other side of the fixture base 2. After both workpieces are installed, the machine tool can be started for processing.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
