Technical Field
[0001] This utility model relates to the field of milling fixture technology, and more specifically, to a fixture for milling long handles. Background Technology
[0002] In modern machining, face milling is a commonly used metalworking technique, widely applied to surface finishing and shape trimming of various workpieces. To improve milling efficiency and machining accuracy, operators often need to use various milling fixtures. However, existing fixtures for face milling with long handles have some significant drawbacks in practical applications, especially in workpiece positioning and clamping.
[0003] First, existing fixtures for milling long handles typically rely on mechanical clamps to hold the workpiece. These clamps are prone to causing the workpiece to shift during milling. This shift not only affects the milling accuracy but can also lead to unevenness on the machined surface, thus reducing the quality of the final product. Utility Model Content

[0005] According to the present invention, a fixture for milling long handles includes a base plate, two clamping assemblies spaced apart on the base plate, each clamping assembly including a support block for supporting at least one long handle, a pressure plate on the side of the long handle away from the support block, a driving part on the side of the base plate away from the support block for driving the pressure plate to press and release the long handle, a limiting block on the side of the base plate near the support block, and a limiting groove on the side of the long handle for engaging with the limiting groove.
[0006] Preferably, the support block has a mating groove on the side away from the base plate, which is used to mate with the long handle.
[0007] Preferably, a limiting post is provided at the mating groove, which is used to abut against the end of the long handle.
[0008] Preferably, the drive unit includes a clamping cylinder with a telescopic piston rod. The piston rod end is provided with a transition shaft, and the end of the transition shaft away from the piston rod abuts against the pressure plate.
[0009] Preferably, the pressure plate is provided with a first mating hole, and a screw is provided at the first mating hole. The piston rod is provided with a corresponding second mating hole, which is used for threaded engagement with the screw. The transition shaft forms a third mating hole along the axial direction, which is used for sliding engagement with the screw.
[0010] Preferably, a guide hole is formed at the support block, which is used for sliding engagement with the transition shaft.
[0011] Preferably, a positioning boss is formed on the side of the clamping cylinder near the base plate, and a corresponding positioning hole is formed on the base plate. The positioning boss is used to insert into the positioning hole when the cylinder is installed.
[0012] Preferably, the bottom plate has two feet spaced apart at the end away from the support block.
[0013] Beneficial effects:
[0014] The pressure plate can clamp the long handle, and at the same time, the limiting block can be engaged in the limiting groove to ensure that the long handle can be stably clamped during milling operations, preventing it from shifting when the milling cutter is milling the long handle, thereby improving the milling accuracy of the long handle.
[0015] Furthermore, the limiting post can prevent the long handle from deviating along its length, thereby better limiting the long handle and improving the stability during milling of the long handle, thus improving the milling quality and efficiency of the long handle. Attached Figure Description

[0021] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.
[0022] Example 1
[0023] Seen in Figure 1-3This embodiment provides a long handle 203 fixture, which includes a base plate 100. Two clamping components 110 are spaced apart on the base plate 100. Each clamping component 110 includes a support block 213 for supporting at least one long handle 203. A pressure plate 111 is provided on the side of the long handle 203 away from the support block 213. A driving part 120 is provided on the side of the base plate 100 away from the support block 213. The driving part 120 is used to drive the pressure plate 111 to press and release the long handle 203. A limiting block 101 is provided on the side of the base plate 100 near the support block 213. A limiting groove 3031 is provided on the long handle 203. The limiting block 101 is used to engage with the limiting groove 3031.
[0024] According to the solution provided in this embodiment, the pressure plate 111 can clamp the long handle 203, and at the same time, the limiting block 101 is engaged in the limiting groove 3031, which can better ensure that the long handle 203 can be stably clamped during milling operations, and prevent it from shifting when the milling cutter mills the long handle 203.
[0025] Specifically, the long handle 203 is clamped at both ends by the pressure plate 111 and the support block 213 at the clamping assembly 110, thereby fixing the long handle 203. The limiting block 101 can prevent the long handle 203 from shifting in the length direction.
[0026] Furthermore, the limit block 101 can also prevent the long handle 203 from being installed backwards, thereby avoiding processing errors.
[0027] Seen in Figure 2 The support block 213 forms a mating groove 2131 on the side away from the base plate 100. The mating groove 2131 is used to conformally mate with the long handle 203.
[0028] Specifically, the support block 213 can support the long handle 203, and the groove 2131 is used to place the long handle 203, so as to better fit the long handle 203.
[0029] Seen in Figure 1-5 The drive unit 120 includes a clamping cylinder 515, which has a telescopic piston rod 5151. The end of the piston rod 5151 is provided with a transition shaft 516, and the end of the transition shaft 516 away from the piston rod 5151 abuts against the pressure plate 111.
[0030] The pressure plate 111 is provided with a first mating hole 5111, and a screw 414 is provided at the first mating hole 5111. The piston rod 5151 is provided with a corresponding second mating hole 5152, which is used to thread with the screw 414. The transition shaft 516 forms a third mating hole 5161 along the axial direction, which is used to slide with the screw 414.
[0031] Specifically, the clamping cylinder 515 can drive the pressure plate 111 to press and release the long handle 203, thereby fixing the long handle 203.
[0032] Furthermore, a guide hole 5132 is formed at the support block 213, which is used for sliding engagement with the transition shaft 516.
[0033] Specifically, the guide hole 5132 can guide the transition shaft 516, thereby making the lifting and lowering of the pressure plate 111 more stable.
[0034] Seen in Figure 5 A positioning boss 5153 is formed on the side of the clamping cylinder 515 near the base plate 100, and a positioning hole 504 is formed on the base plate 100 accordingly. The positioning boss 5153 is used to insert into the positioning hole 504 when the cylinder is installed.
[0035] Specifically, the positioning boss 5153 and the positioning hole 504 effectively achieve the positioning and installation of the clamping cylinder 515.
[0036] Seen in Figure 1-2 Two feet 102 are provided at intervals on one end of the base plate 100 away from the support block 213.
[0037] Specifically, the foot 102 can better lift the base plate 100, thereby facilitating the installation of the clamping cylinder 515.
[0038] Example 2
[0039] This embodiment provides a long handle 203 fixture, which differs from the long handle 203 fixture in Embodiment 1 in that a limiting post 112 is provided at the mating groove 2131, and the limiting post 112 is used to abut against the end of the long handle 203.
[0040] According to the solution provided in this embodiment, the limiting post 112 can prevent the long handle 203 from shifting along the length direction, thereby better limiting the long handle 203 and improving the stability of the long handle 203 during milling.
[0041] Working principle:
[0042] When using this fixture, extend the piston rod 5151 of the clamping cylinder 515, move the pressure plate 111 away from the support block 213, place the long handle 203 in the mating groove 2131, and engage the limiting block 101 with the limiting groove 3031. Then, retract the piston rod 5151 of the clamping cylinder 515, causing the pressure plate 111 to clamp the long handle 203. At this time, the limiting post 112 abuts against both ends of the long handle 203, thus achieving the installation of the long handle 203. At this time, the long handle 203 can be milled. After the milling is completed, extend the piston rod 5151 of the clamping cylinder 515, remove the processed long handle 203.
