Description

Technical Field

[0001] This utility model relates to the field of machining center clamping technology, and in particular to a dual-clamping structure for machining centers. Background Technology

[0002] The workpiece clamping mechanism of a machining center primarily functions to firmly clamp the workpiece during machining, preventing displacement when subjected to cutting forces from the tool. It also accurately positions the workpiece on the machining center's worktable, ensuring the starting position and orientation of the machining process meet requirements. Because it can fix the workpiece and precisely position it, it helps guarantee dimensional, shape, and positional accuracy throughout the entire machining process, thereby producing high-quality products that meet design requirements.

[0003] In the existing technology, when machining two mating parts, different machining centers are usually used to process the two parts separately. Due to errors such as equipment differences and environmental changes, it is easy to make it difficult to guarantee the clearance error after the two parts are mated. Utility Model Content

[0004] To facilitate the simultaneous machining of two mating parts by a machining center, this application provides a dual-clamping structure for a machining center.

[0005] The dual-clamping structure for a machining center provided in this application adopts the following technical solution:

[0006] A dual-clamping structure for a machining center includes a body and a sliding plate, the sliding plate being movably connected to the body. It also includes a clamping structure comprising a mounting base, two fixed bases, and a driving mechanism. The mounting base is detachably connected to the sliding plate. The two fixed bases are respectively mounted on the mounting base, and several clamping blocks are slidably connected to each of the two fixed bases along a central axis perpendicular to the fixed base. The driving mechanism can drive the clamping blocks on the two fixed bases to move simultaneously, or drive the clamping blocks on the clamping blocks of the two fixed bases to move simultaneously.

[0007] By adopting the above technical solution, the clamping blocks on the two fixed seats are moved by the drive assembly to clamp the parts on the corresponding fixed seats respectively; then, the parts on the two fixed seats can be clamped at the same time by driving the two fixed seats simultaneously by driving the clamping blocks on the two fixed seats simultaneously, which is convenient for the machining center to process two mating parts at the same time; the two mating parts are processed at the same time on one machining center, which better ensures the fitting accuracy of the two and reduces the gap error after assembly; the processing steps of the two parts are arranged in a coordinated manner, making full use of the processing time and improving the overall processing efficiency.

[0008] Preferably, the driving mechanism includes two driving discs, two hollow shafts, and an adjusting component. One end face of each of the two driving discs along its axial direction is provided with a planar thread. The two driving discs are coaxial with two fixed seats and rotatably connected to the corresponding fixed seats along their axial direction. A plurality of clamping blocks are provided with planar threaded grooves. The plurality of clamping blocks are threadedly connected to the rotating discs on the corresponding fixed seats. The two hollow shafts are coaxial and fixedly connected to the driving discs. The adjusting component is used to adjust the two hollow shafts to rotate simultaneously or separately.

[0009] By adopting the above technical solution, when the hollow shaft rotates, the drive disc rotates together. Through the threaded connection between the planar thread on the drive disc and the planar threaded grooves on several clamping blocks, the clamping blocks slide along a path perpendicular to the central axis of the drive disc, clamping or releasing the fixed parts. When the adjusting component is adjusted to allow the two hollow shafts to rotate separately, the clamping blocks on the two fixed seats can perform clamping and loosening operations separately. When the adjusting component is adjusted to allow the two hollow shafts to rotate simultaneously, the clamping blocks on the two fixed seats can perform clamping and loosening operations simultaneously. This mechanism can be applied to the simultaneous processing of more parts that require cooperation.

[0010] Preferably, the adjusting assembly includes two first gears, two second gears, and a third gear. The two first gears are coaxial and fixedly connected to a hollow shaft. A sliding seat is slidably connected to the mounting base. The two second gears and the third gear are rotatably connected to the sliding seat. When the sliding seat slides to the first position, the two second gears mesh with the two first gears respectively. When the sliding seat slides to the second position, the third gear meshes with the two first gears simultaneously.

[0011] By adopting the above technical solution, through the sliding sliding seat, when the sliding seat slides to the point where the two second gears mesh with the two first gears respectively, it drives the two first gears to rotate, causing the two hollow shafts to rotate, thereby adjusting the position of the clamping blocks on the two fixed seats respectively; when the sliding seat moves to the point where the third gear meshes with the two first gears simultaneously, it drives the third gear to rotate, causing the two hollow shafts to rotate simultaneously, thereby simultaneously clamping and releasing the clamping blocks on the two fixed seats.

[0012] Preferably, the third gear and the two second gears are respectively coaxially and fixedly connected with force-applying rods, and the ends of the three force-applying rods away from the second gears pass through the mounting base to the outside.

[0013] By adopting the above technical solution, force is applied to the three force grooves extending to the outside, thereby facilitating the rotation of the third gear and the two second gears.

[0014] Preferably, it also includes a force-applying rod, which is provided with a mating block, and the end of the force-applying rod that extends to the outside is provided with a force-applying groove that can mate with the mating block.

[0015] By adopting the above technical solution, the mating block on the force-applying rod is matched with the force-applying groove on the force-applying rod. By applying force to the force-applying rod, the rotation of the force-applying rod can be driven, making it easier to clamp and release the parts.

[0016] Preferably, the sliding seat is provided with an operating handle, which is slidably connected to the mounting seat along the sliding direction of the sliding seat, and one end of the operating handle passes through the mounting seat to the outside.

[0017] By adopting the above technical solution, force is applied to the operating handle to drive the sliding seat to slide, thereby adjusting the meshing between the gears to achieve the adjustment of the two hollow shafts to rotate simultaneously or separately.

[0018] The main technical effects of this utility model are reflected in the following aspects:

[0019] 1. This utility model, by setting up a clamping mechanism, uses a drive assembly to drive the clamping blocks on two fixed seats to move and clamp the parts on the corresponding fixed seats respectively; then, by simply driving the two fixed seats simultaneously to move the clamping blocks on the two fixed seats, the parts on the two fixed seats can be clamped at the same time, which is convenient for the machining center to process two mating parts at the same time; it allows two mating parts to be processed on one machining center at the same time, better ensuring the fitting accuracy of the two parts and reducing the gap error after assembly; it also allows for the overall arrangement of the processing steps of the two parts, making full use of processing time and improving the overall processing efficiency;

[0020] 2. This utility model, by setting up a drive assembly, causes the drive disk to rotate when the hollow shaft rotates. Through the threaded connection between the planar thread on the drive disk and the planar threaded grooves on several clamping blocks, the clamping blocks slide along a path perpendicular to the central axis of the drive disk, clamping or releasing the fixed parts. When the adjustment assembly is adjusted so that the two hollow shafts rotate separately, the clamping blocks on the two fixed seats can perform clamping and loosening operations separately. When the adjustment assembly is adjusted so that the two hollow shafts rotate simultaneously, the clamping blocks on the two fixed seats perform clamping and loosening operations simultaneously. This allows the mechanism to be applied to the simultaneous processing of more parts that require coordination.

[0021] 3. This utility model, by setting an adjustment component and using a sliding sliding seat, when the sliding seat slides to the point where the two second gears mesh with the two first gears respectively, drives the two first gears to rotate, causing the two hollow shafts to rotate, thereby adjusting the position of the clamping blocks on the two fixed seats respectively; when the sliding seat moves to the point where the third gear meshes with the two first gears simultaneously, drives the third gear to rotate, causing the two hollow shafts to rotate simultaneously, thereby simultaneously clamping and releasing the clamping blocks on the two fixed seats.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0028] This application discloses a dual-clamping structure for a machining center.

[0029] Reference Figure 1 and Figure 2This embodiment of a machining center with a dual-clamping structure 3 includes a body 1 and a sliding plate 2. The sliding plate 2 is movably connected inside the body 1. The clamping structure 3 also includes a mounting base 31, two fixed bases 32, and a driving mechanism 34. The mounting base 31 is detachably connected to the sliding plate 2 via a clamping plate. The two fixed bases 32 are respectively fixedly connected to the mounting base 31. Several clamping blocks 33 are slidably connected to the two fixed bases 32 along the central axis perpendicular to the fixed base 32. The several clamping blocks 33 are evenly distributed around the central axis of the corresponding fixed base 32. The driving mechanism 34 can drive the clamping blocks 33 on the two fixed bases 32 to move simultaneously or drive the clamping blocks 33 on the two fixed bases 32 to move simultaneously.

[0030] Reference Figure 1 and Figure 2 The drive assembly drives the clamping blocks 33 on the two fixed seats 32 to move and clamp the parts on the corresponding fixed seats 32 respectively. Then, the drive assembly only needs to drive the two fixed seats 32 to move the clamping blocks 33 on the two fixed seats 32 simultaneously to clamp the parts on the two fixed seats 32 at the same time. This makes it convenient for the machining center to process two mating parts at the same time. It allows the two mating parts to be processed on one machining center at the same time, which better ensures the mating accuracy of the two parts and reduces the gap error after assembly. The machining process of the two parts can be arranged in a coordinated manner to make full use of the machining time and improve the overall machining efficiency.

[0031] Reference Figure 3 and Figure 4 The drive mechanism 34 includes two drive discs 341, two hollow shafts 342, and an adjustment component 35. The two drive discs 341 are provided with a planar thread 3411 on one end face in the axial direction. The two drive discs 341 are coaxial with the two fixed seats 32 and rotatably connected to the corresponding fixed seats 32 in the axial direction. A number of clamping blocks 33 are provided with planar thread 3411 grooves 331. The number of clamping blocks 33 are respectively threaded to the rotating discs on the corresponding fixed seats 32 through planar threads 3411 and planar thread 3411 grooves 331. The two hollow shafts 342 are coaxial and fixedly connected to the drive discs 341. The adjustment component 35 is used to adjust the two hollow shafts 342 to rotate simultaneously or separately.

[0032] Reference Figure 2 and Figure 3When the hollow shaft 342 rotates, the drive disk 341 rotates together. Through the threaded connection between the planar thread 3411 on the drive disk 341 and the planar thread 3411 groove 331 on the clamping blocks 33, the clamping blocks 33 slide along the central axis perpendicular to the drive disk 341, clamping or releasing the fixed parts. When the adjusting component 35 is adjusted to the point where the two hollow shafts 342 rotate separately, the clamping blocks 33 on the two fixed seats 32 can perform clamping and loosening operations respectively. When the adjusting component 35 is adjusted to the point where the two hollow shafts 342 rotate simultaneously, the clamping blocks 33 on the two fixed seats 32 can perform clamping and loosening operations simultaneously. This mechanism can be applied to the simultaneous processing of more parts that need to be matched.

[0033] Reference Figure 1 and Figure 2 The adjusting assembly 35 includes two first gears 351, two second gears 352, and a third gear 353. The two first gears 351 are coaxially and fixedly connected to the hollow shaft 342. A sliding seat is slidably connected to the mounting base 31. The two second gears 352 and the third gear 353 are rotatably connected to the sliding seat. When the sliding seat slides to the first position, the two second gears 352 are engaged with the two first gears 351 respectively. When the sliding seat slides to the second position, the third gear 353 is engaged with both first gears 351 simultaneously. A force-applying rod 354 is coaxially and fixedly connected to the third gear 353 and the two second gears 352 respectively. The ends of the three force-applying rods 354 away from the second gears 352 pass through the mounting base 31 to the outside.

[0034] Reference Figure 1 and Figure 2 By using a sliding sliding seat, when the sliding seat slides to the point where the two second gears 352 mesh with the two first gears 351 respectively, it drives the two first gears 351 to rotate, causing the two hollow shafts 342 to rotate, thereby adjusting the position of the clamping blocks 33 on the two fixed seats 32 respectively. When the sliding seat moves to the point where the third gear 353 meshes with the two first gears 351 simultaneously, it drives the third gear 353 to rotate, causing the two hollow shafts 342 to rotate simultaneously, thereby simultaneously clamping and releasing the clamping blocks 33 on the two fixed seats 32. By applying force to the three force grooves 355 extending to the outside, it facilitates the rotation of the third gear 353 and the two second gears 352.

[0035] Reference Figure 2 and Figure 3It also includes a force-applying rod 4, on which a mating block 41 is fixedly connected. One end of a force-applying rod 354 extending to the outside has a force-applying groove 355 that mates with the mating block 41. By engaging the mating block 41 on the force-applying rod 4 with the force-applying groove 355 on the force-applying rod 354, force is applied to the force-applying rod 4, facilitating the rotation of the force-applying rod 354 and making clamping and releasing parts easier. An operating handle 356 is fixedly connected to the sliding seat. The operating handle is slidably connected to the mounting base 31 along the sliding direction of the sliding seat. A hydraulic cylinder is fixedly connected to the sliding seat to reduce the possibility of displacement of the sliding seat without force. One end of the operating handle 356 extends through the mounting base 31 to the outside. By applying force to the operating handle 356, the sliding seat is driven to slide, thereby adjusting the meshing between the gears to achieve simultaneous or separate rotation of the two hollow shafts 342.

[0036] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
