[0027] Please see Figures 1-8 The clamping device 100 in this embodiment has intersecting first direction M, second direction N, and third direction P. In this embodiment, the first direction M, second direction N, and third direction P are perpendicular to each other; in other embodiments, the first direction M, second direction N, and third direction P may not be perpendicular.
[0028] Please see Figure 1 and Figure 2 The clamping device 100 is used to clamp the workpiece 200 to be clamped. The workpiece 200 to be clamped has a processing end 201 and an abutment end 202 in the first direction M. In this embodiment, the workpiece 200 to be clamped is a push rod. It is worth noting that the push rod in this embodiment is a rigid push rod, not a flexible push rod.
[0029] Please see Figure 1 and Figure 2 The clamping device 100 includes: a base 1, an end plate 2, a sliding plate 3, a locking component 4, a limiting component 5, a positioning component 6, and a fastener 7.
[0030] Please see Figure 3The base 1 has at least one groove 11 on its surface, each groove 11 extending along a first direction M. In this embodiment, the base 1 has two grooves 11 on the surface of the base 1 on the side near the slide plate 3 in a third direction P. The size of each groove 11 in the first direction M is the same as the size of the base 1 in the first direction M. In other words, the groove 11 in this embodiment penetrates both end faces of the base 1 in the first direction M.
[0031] Please see Figure 3 The base 1 is provided with at least one positioning groove 12, which is disposed on the surface of the base 1 near the end plate 2. In this embodiment, two positioning grooves 12 are provided on the surface of the base 1 near the end plate 2, and the two positioning grooves 12 are arranged at intervals along the second direction N.
[0032] Please see Figure 3 The base 1 is provided with at least one fastening groove 13, which is disposed on the surface of the base 1 near the end plate 2. In this embodiment, the surface of the base 1 near the end plate 2 is provided with three fastening grooves 13, which are arranged at intervals along the second direction N. The three fastening grooves 13 and the two positioning grooves 12 are arranged alternately along the second direction N.
[0033] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The end plate 2 is connected to one end of the base 1 in the first direction M.
[0034] Please see Figure 4 and Figure 5 The end plate 2 has at least one mounting hole 21. Each mounting hole 21 penetrates the end plate 2 along a first direction M and is used to support the end 201 to be processed. In this embodiment, the end plate 2 has multiple mounting holes 21, which are arranged along a second direction N. More preferably, the multiple mounting holes 21 are arranged at intervals along the second direction N. By providing at least one mounting hole 21 on the end plate 2, the clamping device 100 can simultaneously, quickly, and accurately process multiple parts to be clamped 200, thereby improving the processing efficiency of the parts to be clamped 200 and reducing production costs.
[0035] Please see Figure 4 , Figure 5 and Figure 7In the plane formed by the second direction N and the third direction P, the orthographic projection of each mounting hole 21 is an isosceles triangle. The apex of the mounting hole 21 is located on the side of its base closest to the base 1, and the perpendicular bisector of its base is parallel to the third direction P. Thus, the two sides of the mounting hole 21 are used to position the workpiece 200 in the second direction N, preventing it from moving in that direction. In this embodiment, the orthographic projection of each mounting hole 21 in the plane formed by the second direction N and the third direction P is an equilateral triangle. This improves the structural stability of the mounting hole 21.
[0036] Please see Figure 4 The end plate 2 is provided with at least one locking hole 22. Each locking hole 22 extends along a third direction P and communicates with a mounting hole 21. Specifically, the end of the locking hole 22 near the base 1 in the third direction P communicates with the end of the mounting hole 21 away from the base 1 in the third direction P.
[0037] Please see Figure 4 and Figure 5 The end plate 2 is provided with at least one positioning hole 23. The positioning hole 23 penetrates the end plate 2 along the first direction M, and each positioning hole 23 is provided in a one-to-one correspondence with a positioning groove 12. That is, each positioning hole 23 is provided in a corresponding positioning groove 12.
[0038] Please see Figure 1 Each positioning element 6 has one end disposed in a positioning groove 12 and the other end disposed in a positioning hole 23 to position the end plate 2 and the base 1. In this embodiment, the positioning element 6 is a positioning pin.
[0039] Please see Figure 4 and Figure 5 The end plate 2 is provided with at least one fastening hole 24, which penetrates the end plate 2 along the first direction M. Each fastening hole 24 is provided in a one-to-one correspondence with a fastening groove 13. That is, each fastening hole 24 is provided in a corresponding fastening groove 13.
[0040] Please see Figure 1 Each fastener 7 passes through a fastening hole 24 and engages with a fastening groove 13 to secure the end plate 2 and the base 1. In this embodiment, the fastener 7 is a fastening screw.
[0041] Please see Figure 1 , Figure 2 and Figure 6 The sliding plate 3 is slidably connected to the base 1 along the first direction M. The sliding plate 3 is used to abut against the abutment end 202. In this embodiment, the sliding plate 3 includes a main body 31 and at least one slider part 32. The main body 31 is used to abut against the abutment end 202. The main body 31 of the sliding plate 3 is used to position the clamping member 200 in the first direction M.
[0042] Please see Figure 1 , Figure 2 and Figure 6 The slider portion 32 protrudes from the surface of the main body portion 31 on the side near the base 1, and the slider portions 32 are correspondingly embedded in the slide groove 11. In this embodiment, the slide plate 3 includes two slider portions 32, each slider portion 32 is embedded in a slide groove 11, so as to realize that the slide plate 3 is slidably connected to the base 1 in the first direction M.
[0043] Please see Figure 1 , Figure 2 and Figure 7 Each locking element 4 passes through a locking hole 22 to press against the end 201 to be processed. The locking element 4 includes a locking rod 41, a locking head 42, and a locking cap 43. The locking head 42 and the locking cap 43 are respectively connected to the two ends of the locking rod 41 in a third direction P. The locking cap 43 is located outside the mounting hole 21, and the locking head 42 is located inside the mounting hole 21 and presses against the end 201 to be processed. Specifically, the outer wall of the locking rod 41 has a locking external thread (not shown), and the inner wall of the locking hole 22 has a locking internal thread (not shown) that mates with the locking external thread. The locking element 4 and the end plate 2 are connected by the mutual engagement of the locking external thread (not shown) of the locking rod 41 and the locking internal thread (not shown) of the locking hole 22.
[0044] Please see Figure 2 and Figure 7 The locking head 42 is shaped like a frustum, and the diameter of the end of the locking head 42 away from the locking rod 41 is smaller than the diameter of the end of the locking head 42 near the locking rod 41. By pressing the locking head 42 against the workpiece 200 to be processed end 201, the workpiece 200 to be clamped is positioned in the third direction P.
[0045] Please see Figure 1 , Figure 2 and Figure 8 The clamping device 100 also includes a limiting structure. The limiting structure is used to limit the slide plate 3. Specifically, when the slide plate 3 adjusts the workpiece 200 to be clamped to the required processing size, the limiting structure limits the slide plate 3 to prevent it from sliding relative to the base 1, thereby improving the clamping accuracy of the clamping device 100.
[0046] Please see Figure 1 , Figure 2 , Figure 6 and Figure 8 The dimension L1 of the slide groove 11 on the side closer to the main body 31 in the second direction N is smaller than the dimension L2 of the side of the slide groove 11 away from the main body 31 in the second direction N. The slide plate 3 has a limiting hole 33, which penetrates the main body 31 along the third direction M, and the inner wall of the limiting hole 33 has a limiting internal thread (not shown).
[0047] Please see Figure 1 , Figure 2 and Figure 8 The limiting member 5 includes a limiting rod 51 and a limiting cap 52 connected together. The outer wall of the limiting rod 51 has a limiting external thread (not shown) that mates with the limiting internal thread. The end face of the limiting rod 51 near the base 1 presses against the base 1. When the slide plate 3 adjusts the clamping part 200 to the required size, the limiting external thread (not shown) of the limiting member 5 and the limiting internal thread (not shown) of the limiting hole 33 cooperate with each other. When the limiting rod 51 presses against the base 1 near the end face of the base 1, the limiting member 5 continues to rotate, applying a force to the main body 31 in the third direction P away from the base 1. At this time, the main body 31 drives the slider part 32 to move in the groove 11 away from the base 1 in the third direction P. Since the dimension L1 of the side of the groove 11 near the main body 31 in the second direction N is smaller than the dimension L2 of the side of the groove 11 away from the main body 31 in the second direction N, the slider part 32 presses tightly against the groove opening of the side of the groove 11 near the main body 31, thereby preventing the slide plate 3 from moving relative to the base 1.
[0048] In some embodiments, when using the clamping device 100 of this application, the base 1 is first installed on the workbench; then the positioning member 6 is installed in the positioning groove 12 of the base 1; then the positioning hole 23 of the end plate 2 is fitted onto the positioning member 6; then the fastener 7 passes through the fastening hole 24 of the end plate 2 and cooperates with the fastening groove 13 on the base 1 to achieve a fixed connection between the end plate 2 and the base 1; then the side of the slider portion 32 of the slide plate 3 away from the end plate 2 is embedded in the slide groove 11; then the clamping member (push rod) 20 is clamped. The end 201 to be processed of 0 is installed in the mounting hole 21 of the end plate 2. The end 201 to be processed of the clamping part (push rod) 200 is pressed by the locking member 4. The abutting end 202 of the clamping part (push rod) 200 is raised to abut against the surface of the main body 31 of the slide plate 3 near the end plate 2. The end 201 to be processed is moved to a suitable position by moving the slide plate 3 toward the end plate 2 in the first direction M. Then the locking member 4 is locked to fix the clamping part to be processed, and the locking limit member 5 is locked to prevent the slide plate 3 from sliding relative to the base 1.
[0049] In other embodiments, when using the clamping device 100 of this application, the base 1 is first installed on the workbench; then the positioning member 6 is installed in the positioning groove 12 of the base 1; then the positioning hole 23 of the end plate 2 is fitted onto the positioning member 6; then the fastener 7 passes through the fastening hole 24 of the end plate 2 and cooperates with the fastening groove 13 on the base 1 to achieve a fixed connection between the end plate 2 and the base 1; then the side of the sliding groove 11 of the slider part 32 of the slide plate 3 away from the end plate 2 is embedded in the groove 11; then the end 201 of the part to be clamped (push rod) 200 to be processed is installed on the end plate 2. Inside the mounting hole 21, the locking member 4 presses against the processing end 201 of the clamping member (push rod) 200 to be installed, causing the abutting end of the clamping member (push rod) 200 to be lifted up; by calculating the preset position of the slide plate 3, the slide plate 3 is moved to the required preset position, and then the processing end 201 of the clamping member 200 to be installed is pushed towards the slide plate 3, so that the abutting end 202 of the clamping member 200 abuts against the surface of the main body 31 of the slide plate 3 near the end plate 2. Then the locking member 4 is locked to fix the clamping member to be installed, and the locking limit member 5 is locked to prevent the slide plate 3 from sliding relative to the base 1.
[0050] In summary, the clamping device 100 of this application clamps and fixes the end 201 of the workpiece 200 to be processed by the cooperation of the mounting hole 21 and the locking member 4 on the end plate 2. The mounting hole 21 achieves positioning of the workpiece 200 in the second direction N, the locking member 4 achieves positioning of the workpiece 200 in the third direction P, and the sliding plate 3 achieves positioning of the workpiece 200 in the first direction M. The mounting hole 21, the locking member 4 and the sliding plate 3 can quickly and accurately position the workpiece 200 without the need for calibration. Therefore, it is suitable for processing fine, easily deformable and numerous workpieces 200 to be processed. Moreover, the structure is simple and easy to assemble.
