Abstract
Description
Technical Field
[0001] This application relates to the field of machining technology, specifically to a machining fixture. Background Technology
[0002] In the machining of long, strip-shaped workpieces (such as ultrasonic scissor bars), workpiece fixation is a crucial step in ensuring machining accuracy. Currently, the industry commonly uses specialized fixtures to fix workpieces. However, due to the varying lengths of different workpiece models, existing fixtures are typically only suitable for fixing workpieces of a single length, resulting in poor fixture versatility. For workpieces of different lengths, companies need to equip themselves with multiple specialized fixtures, which not only increases equipment costs but also brings inconvenience in storage and management. Furthermore, when machining workpieces of different lengths, operators need to frequently disassemble and change fixtures, a process that is not only time-consuming and labor-intensive but also reduces operational efficiency and affects the overall operational efficiency of the production line. Utility Model Content
[0003] In view of the above, it is necessary to propose a machining fixture that can be adapted to fix workpieces of various lengths, has good versatility, thereby reducing production costs; and does not need to be disassembled from the machining table during the adjustment process, thus improving work efficiency.
[0004] This application provides a processing fixture, comprising: a base including a support plate, the support plate having a plurality of positioning holes and a plurality of first locking holes, the plurality of positioning holes and the plurality of first locking holes being sequentially spaced along a first direction, and the positioning holes and corresponding first locking holes being spaced along a second direction perpendicular to the first direction; and a plurality of first pressing components, each of the first pressing components including a material carrier, a first positioning pin, a first locking component, a first driving component, and a first pressing component, the material carrier being detachably connected to the support plate and used to support a workpiece, the first positioning pin being disposed on the side of the material carrier facing the support plate, the first positioning pin being used to insert into the positioning hole to position the material carrier, the first locking component passing through the material carrier and connected to the support plate through the first locking hole to fix the material carrier, the first driving component being connected to the material carrier, the first pressing component being connected to the first driving component and disposed on the side of the material carrier away from the support plate, the first driving component being used to drive the first pressing component to move closer to or away from the material carrier to press or release the workpiece.

During adjustment, the machining fixture does not need to be disassembled from the machining machine; only the positions of the first holding components need to be adjusted. This not only reduces the machine's downtime but also significantly improves operational efficiency.

The X-axis direction, Y-axis direction, and Z-axis direction are perpendicular to each other.
[0023] Please see Figure 1 , Figure 2 and Figure 3 This application provides a machining fixture 100. The machining fixture 100 is used to fix a workpiece 200, which can be a long strip structure, such as an ultrasonic shovel shank. The machining fixture 100 can be installed inside a machining machine (not shown). After the machining fixture 100 fixes the workpiece 200, the machining machine performs machining on the workpiece 200. In this embodiment, the machining fixture 100 is used to cooperate with the machining machine to machine certain parts of the workpiece 200, rather than machining the entire workpiece 200. However, this is not a limitation of the embodiments of this application.
[0024] The machining fixture 100 includes a base 10 and a plurality of first holding components 20.
[0025] Specifically, the base 10 includes a support plate 11, on which a plurality of positioning holes 111 and a plurality of first locking holes 112 are provided. The plurality of positioning holes 111 are arranged at intervals along a first direction, and the plurality of first locking holes 112 are arranged at intervals along a first direction. The positioning holes 111 and the corresponding first locking holes 112 are arranged at intervals along a second direction perpendicular to the first direction.
[0026] It is understood that the length of the support plate 11 is greater than the length of the workpiece 200 to be processed. The number of positioning holes 111 and first locking holes 112 opened on the support plate 11 can be twenty, thirty, forty, fifty, etc., and the specific number can be set according to the actual size of the support plate 11, which is not limited here. In this embodiment, the positioning holes 111 can be provided in two rows, and the two rows of positioning holes 111 are spaced apart along the second direction. The first locking holes 112 can also be provided in two rows, and the two rows of first locking holes 112 are spaced apart along the second direction. In other embodiments, the positioning holes 111 and the first locking holes 112 can also be provided in three, four, or more rows, which depends on the actual needs and is not limited here.
[0027] The first pressing and holding assembly 20 can be provided in two, three, four, etc., depending on actual needs, and is not limited here. Each first pressing and holding assembly 20 includes a material carrier 21, a first positioning pin 22, a first locking member 23, a first driving member 24, and a first pressing member 25. The material carrier 21 is detachably connected to the support plate 11 and is used to support the workpiece 200. The first positioning pin 22 is located on the side of the material carrier 21 facing the support plate 11. The first positioning pin 22 is used to insert into the positioning hole 111 to position the material carrier 21. The first locking member 23 passes through the material carrier 21 and is connected to the support plate 11 through the first locking hole 112 to fix the material carrier 21. The first driving member 24 is connected to the material carrier 21. The first pressing member 25 is connected to the first driving member 24 and is located on the side of the material carrier 21 away from the support plate 11. The first driving member 24 is used to drive the first pressing member 25 to move closer to or away from the material carrier 21 to press or release the workpiece 200.
[0028] The material carrier 21 is generally plate-shaped, the first positioning pin 22 is column-shaped, and the first locking member 23 can be a bolt, etc. In this embodiment, the first locking member 23 can be a bolt with external threads, and the first locking hole 112 can be a threaded hole with a matching internal thread. The first locking member 23 and the first locking hole 112 are connected by threads. The first driving member 24 can be a cylinder, etc., and the first holding member 25 can be plate-shaped. In this embodiment, the first driving member 24 is a telescopic rotary cylinder. When holding the workpiece 200, the first driving member 24 first drives the first holding member 25 to rotate around a third direction perpendicular to the first and second directions, so that the first holding member 25 rotates to extend along the second direction and correspond to the workpiece 200. Then, the first driving member 24 drives the first holding member 25 to move towards the material carrier 21 along the third direction, thereby making the first holding member 25 cooperate with the material carrier 21 to fix the workpiece 200. When the workpiece 200 is released, the first driving member 24 drives the first holding member 25 to move away from the loading member 21 along a third direction, and then drives the first holding member 25 to rotate around the third direction until the first holding member 25 extends along the first direction, thereby avoiding the workpiece 200 and facilitating the loading member 21 to pick up and put down the material.
[0029] In this embodiment, three first pressing components 20 are provided, two of which correspond to the two ends of the workpiece 200 respectively, and the other first pressing component 20 corresponds to the middle of the workpiece 200, which can improve the stability of fixing the workpiece 200.
[0030] In order to improve the stability of the connection between the loading component 21 and the support plate 11, the loading component 21 can be provided with a first positioning pin 22 and a first locking component 23 at both ends along the second direction, so as to simultaneously position and fix the loading component 21 from both ends.
[0031] The processing fixture 100 provided in this embodiment supports multiple first pressing components 20 via a support plate 11 of a base 10. The support plate 11 has multiple positioning holes 111 and multiple first locking holes 112 for positioning and fixing the first pressing components 20. The material carrier 21 in the first pressing component 20 is inserted into the positioning hole 111 via a first positioning pin 22 to achieve precise positioning of the material carrier 21. Simultaneously, the material carrier 21 is firmly locked onto the support plate 11 by the cooperation of the first locking component 23 with the first locking hole 112. The multiple material carriers 21 cooperate to carry the workpiece 200, and the first pressing component 25 is driven by the first driving component 24 to press the workpiece 200, thereby achieving stable fixing of the workpiece 200. Furthermore, the multiple first pressing components 20 can flexibly adjust their connection positions on the support plate 11 according to the length of the workpiece 200, thereby adapting to workpieces 200 of different lengths, significantly improving the versatility of the fixture and effectively reducing production costs. During the adjustment process, the machining fixture 100 does not need to be disassembled from the machining table; only the position of the first holding component 20 needs to be adjusted. This not only reduces the standby time of the machining table but also greatly improves the work efficiency.
[0032] In some embodiments, see Figure 1 , Figure 2 and Figure 3 At least one of the first holding components 20 has a relief groove 211 on its loading member 21. The relief groove 211 corresponds to the processing position of the workpiece 200 and provides clearance space for the processing position of the workpiece 200. By providing a relief groove 211 on the loading member 21, which corresponds to the processing position of the workpiece 200, sufficient clearance space can be provided for the processing area of the workpiece 200, so that the processing tools (such as cutting tools, drill bits, etc.) will not interfere with the loading member 21 during operation, ensuring the smooth progress of the processing. In this embodiment, one end of the workpiece 200 needs to be processed, and a relief groove 211 is provided on the loading member 21 of the first holding component 20 corresponding to the end of the workpiece 200 that needs to be processed. If both ends of the workpiece 200 need to be processed, or if the middle of the workpiece 200 needs to be processed, relief grooves 211 can be provided on the loading members 21 of two or more first holding components 20.
[0033] In some embodiments, see Figure 1 , Figure 2 and Figure 3The loading component 21 has a loading groove 212 extending along a first direction, which is used to accommodate and position the workpiece 200. By providing the loading groove 212 extending along the first direction on the loading component 21, the loading groove 212 can accommodate and position the workpiece 200, ensuring that the workpiece 200 maintains a stable position during processing. This makes the installation and positioning of the workpiece 200 more accurate and reduces processing errors caused by workpiece 200 offset or loosening. The design of the loading groove 212 allows the workpiece 200 to be quickly and accurately installed onto the fixture, reducing adjustment and calibration time and thus improving overall processing efficiency. The loading groove 212 can be designed according to the shape and size of different workpieces 200, allowing the same fixture to adapt to the processing needs of multiple workpieces 200, improving the versatility and flexibility of the fixture. In this embodiment, the cross-section of the loading groove 212 in the YZ plane is V-shaped, which improves the stability when carrying the workpiece 200.
[0034] In some embodiments, see Figure 2 and Figure 3 The workpiece 200 has a protrusion 201, and the loading component 21 has a positioning groove 213 that matches the protrusion 201. The positioning groove 213 is used to accommodate the protrusion 201 for positioning the workpiece 200. By providing a positioning groove 213 on the loading component 21 that matches the protrusion 201 of the workpiece 200, the positioning groove 213 can accurately accommodate the protrusion 201 of the workpiece 200, thereby achieving high-precision positioning of the workpiece 200. The cooperation between the positioning groove 213 and the protrusion 201 of the workpiece 200 can restrict the degree of freedom of the workpiece 200, preventing the workpiece 200 from moving or vibrating during processing, thereby improving the stability and consistency of processing. The design of the positioning groove 213 makes the installation of the workpiece 200 simpler. The operator only needs to align the protrusion 201 of the workpiece 200 with the positioning groove 213 to complete the positioning, reducing the time for adjustment and calibration and improving production efficiency.
[0035] It is understood that the clearance groove 211, the loading groove 212 and the positioning groove 213 on the loading component 21 can be provided in multiple intervals along the second direction, such as two, three, four, etc., so that multiple workpieces 200 can be fixed at the same time, thereby improving processing efficiency.
[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 3The support plate 11 also has a plurality of second locking holes 113, which are arranged sequentially at intervals along a first direction. The second locking holes 113 and the positioning holes 111 are arranged at intervals along a second direction. The second locking holes 113 are located on the side of the positioning holes 111 opposite to the first locking holes 112. The processing fixture 100 also includes a second pressing assembly 30, which includes a connecting plate 31, a second locking member 32, a second driving member 33, and a second pressing member 34. The connecting plate 31 is located close to the material carrier 21 with the clearance groove 211. The second locking member 32 passes through the connecting plate 31 and is connected to the support plate 11 through the second locking holes 113. The second driving member 33 is connected to the connecting plate 31, and the second pressing member 34 is connected to the second driving member 33. The second driving member 33 is used to drive the second pressing member 34 to move closer to or away from the material carrier 21 to press or release the workpiece 200.
[0037] The number of second locking holes 113 can be twenty, thirty, forty, etc., and the specific number can be set according to the actual size of the support plate 11, and is not limited here. In this embodiment, the second locking holes 113 can be provided in two rows, and the two rows of second locking holes 113 are spaced apart along the second direction. In this embodiment, there can be two second pressing components 30, which are symmetrically arranged along the second direction and are respectively connected to the support plate 11 through the two rows of second locking holes 113. The second locking member 32 can be a bolt with external threads, and the second locking hole 113 can be a threaded hole with a matching internal thread. The second locking member 32 and the second locking hole 113 are connected by threads. In this embodiment, each connecting plate 31 can be provided with two second locking members 32 to improve the stability of the connection between the connecting plate 31 and the support plate 11.
[0038] The second driving member 33 can be a telescopic rotary cylinder, and the second pressing member 34 is a plate-shaped structure. When pressing the workpiece 200, the second driving member 33 first drives the second pressing member 34 to rotate around a third direction, so that the second pressing member 34 rotates to extend along a second direction and correspond to the workpiece 200. Then, the second driving member 33 drives the second pressing member 34 to move towards the loading member 21 along a third direction, thereby making the second pressing member 34 cooperate with the loading member 21 to fix the workpiece 200. When releasing the workpiece 200, the second driving member 33 drives the second pressing member 34 away from the loading member 21 along a third direction, and then drives the second pressing member 34 to rotate around a third direction until the second pressing member 34 extends along a first direction, thereby avoiding the workpiece 200 and facilitating the loading and unloading of materials on the loading member 21.
[0039] In some embodiments, see Figure 2 and Figure 3The connecting plate 31 has an adjustment hole 311 extending in the first direction. The second locking member 32 is inserted into the adjustment hole 311 to connect the support plate 11 and the connecting plate 31. In this embodiment, the adjustment hole 311 is a strip-shaped hole. By providing the adjustment hole 311, after adjusting the position of the second pressing component 30, the adjustment hole 311 can always correspond to the second locking hole 113, which facilitates the installation of the second locking member 32.
[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first pressing assembly 20 further includes a first flexible member 26, which is disposed on the side of the first pressing member 25 facing the material carrier 21. The first flexible member 26 is used to flexibly press the workpiece 200. The second pressing assembly 30 further includes a second flexible member 35, which is disposed on the side of the second pressing member 34 facing the material carrier 21. The second flexible member 35 is used to flexibly press the workpiece 200. Both the first flexible member 26 and the second flexible member 35 can be made of materials such as urethane. The first flexible member 26 and the second flexible member 35 can provide a soft contact surface, avoiding direct hard contact between the pressing member and the workpiece 200, thereby preventing scratches, indentations or other damage to the surface of the workpiece 200 due to pressing. This is especially suitable for workpieces 200 with high surface quality requirements. The first flexible member 26 and the second flexible member 35 can better conform to the shape of the workpiece 200. Even if the surface of the workpiece 200 has an irregular shape or curved surface, the first flexible member 26 and the second flexible member 35 can distribute pressure evenly, reducing the risk of local overpressure.
[0041] In some embodiments, see Figure 1 and Figure 3 The machining fixture 100 also includes a plurality of positioning components 40. The plurality of positioning components 40 are spaced apart along a first direction on the support plate 11 and between two adjacent first pressing components 20. Each positioning component 40 includes a positioning plate 41, a second positioning pin 42, a third locking member 43 and two limiting pins 44. The positioning plate 41 is detachably connected to the support plate 11 and is used to support the workpiece 200. The second positioning pin 42 is located on the side of the positioning plate 41 facing the support plate 11 and is used to insert into the positioning hole 111 to position the positioning plate 41. The third locking member 43 passes through the positioning plate 41 and is connected to the support plate 11 through the first locking hole 112 to fix the positioning plate 41. The two limiting pins 44 are both located on the side of the positioning plate 41 away from the support plate 11 and are spaced apart along a second direction and are configured to position the workpiece 200.
[0042] The positioning assembly 40 can be provided in two or three configurations. The third locking component 43 can be a bolt with external threads, etc. When installing the positioning assembly 40, the positioning plate 41 is positioned by inserting the second positioning pin 42 into the positioning hole 111, and then the positioning plate 41 is locked to the support plate 11 by the third locking component 43. When installing the workpiece 200, the workpiece 200 can be placed between the two limit pins 44 to perform preliminary positioning of the workpiece 200, so that the workpiece 200 can be accurately placed in the loading groove 212 of the loading component 21.
[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Multiple positioning holes 111 are equidistantly distributed along a first direction, and multiple first locking holes 112 are equidistantly distributed along the first direction, with the distance between two adjacent positioning holes 111 being an integer multiple of the distance between two adjacent first locking holes 112. Multiple second locking holes 113 are equidistantly distributed along the first direction, with the distance between two adjacent second locking holes 113 being less than or equal to the length of the adjusting hole 311 along the first direction.
[0044] By equidistantly distributing multiple positioning holes 111, first locking holes 112, and second locking holes 113 along a first direction, and ensuring that the distance between two adjacent positioning holes 111 is an integer multiple of the distance between two adjacent first locking holes 112, the accuracy and consistency of positioning and locking are ensured. The equidistant distribution of the positioning holes 111, first locking holes 112, and second locking holes 113 allows the material carrier 21, connecting plate 31, and positioning plate 41 to be installed and adjusted at fixed intervals, enhancing the modularity of the machining fixture 100.
[0045] In this embodiment, the distance between two adjacent positioning holes 111 ranges from 24mm to 36mm, preferably 30mm; the distance between two adjacent first locking holes 112 ranges from 8mm to 12mm, preferably 10mm; and the distance between two adjacent second locking holes 113 ranges from 12mm to 18mm, preferably 15mm. It is understood that the distances between two adjacent positioning holes 111, two adjacent first locking holes 112, and two adjacent second locking holes 113 can also be other values, and can be set according to actual production needs, and are not limited here.
[0046] By equidistantly setting the positioning holes 111 and the first locking holes 112, and making the distance between two adjacent positioning holes 111 an integer multiple of the distance between two adjacent first locking holes 112, the relative position of each positioning hole 111 and its nearest adjacent first locking hole 112 can be kept consistent, such as being on the same straight line in the second direction or being staggered in the second direction. This allows the first locking member 23 to correspond to one of the first locking holes 112 after the material carrier 21 is positioned by the first positioning pin 22, and the third locking member 43 to correspond to one of the first locking holes 112 after the positioning plate 41 is positioned by the second positioning pin 42, which facilitates the adjustment of the position of the material carrier 21 and the positioning plate 41.
[0047] By equidistantly arranging multiple second locking holes 113 along the first direction, and with the distance between two adjacent second locking holes 113 being less than or equal to the length of the adjusting hole 311 along the first direction, the adjusting hole 311 can always correspond to some of the second locking holes 113 after the connecting plate 31 is adjusted to its position on the support plate 11 along the first direction, making it convenient for the second locking member 32 to lock the connecting plate 31 and the support plate 11 together.
[0048] Further, in this embodiment, the plurality of positioning holes 111 are divided into an adjacent first group and a second group along the first direction. The positioning holes 111 in both the first and second groups are equidistantly distributed along the first direction. The distance between two adjacent positioning holes 111 in the first group is equal to the distance between two adjacent positioning holes 111 in the second group. Furthermore, the distance between the two closest positioning holes 111 in the first and second groups is different from the distance between two adjacent positioning holes 111 in either the first or second group. Specifically, each positioning hole 111 in the first group and its nearest adjacent first locking hole 112 are located on the same straight line in the second direction, while each positioning hole 111 in the second group and its nearest adjacent first locking hole 112 are staggered in the second direction. Correspondingly, the first positioning pin 22 and the first locking member 23 installed on the material carrier 21 of the first set of positioning holes 111 are located on the same straight line in the second direction, while the first positioning pin 22 and the first locking member 23 installed on the material carrier 21 of the second set of positioning holes 111 are staggered in the second direction. It can be understood that when processing the workpiece 200, the part of the workpiece 200 to be processed needs to be opposite to the processing tool (not shown). In one embodiment of this application, one of the material carriers 21 is provided with a clearance groove 211 corresponding to the processing position. Therefore, the material carrier 21 with the clearance groove 211 needs to be installed below the processing tool. By setting the positioning holes 111 into two sets, the relative positions of the first positioning pin 22 and the first locking member 23 on the material carrier 21 with the clearance groove 211 can be different from the relative positions of the first positioning pin 22 and the first locking member 23 on other material carriers 21, thereby playing a foolproof role. This can prevent damage caused by machining errors of workpiece 200, and also avoid wasting time on readjustment due to incorrect installation of the load component 21.
[0049] In some embodiments, see Figure 1 and Figure 2 The base 10 also includes a connecting seat 12, which is connected to the side of the support plate 11 opposite to the material carrier 21. The connecting seat 12 is used to support the support plate 11. By providing the connecting seat 12, while supporting the support plate 11, it also provides space for the first driving member 24 and the second driving member 33, preventing interference between the first driving member 24 and the second driving member 33 and external equipment, and protecting the first driving member 24 and the second driving member 33. In this embodiment, the connecting seat 12 is also used to connect to the processing machine table to improve the stability of the processing fixture 100 during use.
[0050] The working process of the machining fixture 100 provided in this embodiment is roughly as follows:
[0051] First, adjust the positions of multiple first pressing components 20 on the support plate 11 according to the length of the workpiece 200 to be processed. When installing the first pressing component 20, insert the first positioning pin 22 on the loading component 21 into the corresponding positioning hole 111, and then connect it to the corresponding first locking hole 112 through the first locking component 23 to fix the loading component 21. Then, install the second pressing component 30 at the position corresponding to the loading component 21 with the clearance hole. During installation, lock the connecting plate 31 to the support plate 11 through the second locking component 32. Then, install multiple positioning components 40 between two adjacent first pressing components 20. During installation, insert the second positioning pin 42 into the corresponding positioning hole 111, and then connect it to the corresponding first locking hole 112 through the third locking component 43 to fix the positioning plate 41.
[0052] Before installing workpiece 200, the first driving component 24 drives the first holding component 25 to rotate away from the corresponding material carrier 21, and the second driving component 33 drives the second holding component 34 to rotate away from the corresponding material carrier 21, thus completing the preparation before installing workpiece 200.
[0053] When installing workpiece 200, it is passed between the two limiting members of positioning assembly 40 for initial positioning. Then, the part of workpiece 200 to be processed is placed in the clearance groove 211, the other part of workpiece 200 is placed in the corresponding material loading groove 212, and the protrusion 201 of workpiece 200 is engaged in the positioning groove 213, thus completing the placement of workpiece 200. Then, the first driving member 24 and the second driving member 33 respectively drive the first pressing member 25 and the second pressing member 34 to rotate and approach the corresponding material loading member 21, thereby enabling the first pressing member 25 and the second pressing member 34 to cooperate with the material loading member 21 to press and hold workpiece 200, completing the positioning and fixing of workpiece 200, and then processing can be carried out.
[0054] When it is necessary to process workpieces of other lengths 200, the first pressing component 20, the second pressing component 30 and the positioning component 40 are removed from the support plate 11 and then installed on the support plate 11 at the corresponding positions according to actual needs.
