Description

Technical Field

[0001] This utility model belongs to the field of milling clamping tooling technology, specifically relating to an outer cover milling hole clamping device. Background Technology

[0002] Motor vehicle component covers refer to parts installed on the exterior of a motor vehicle, primarily serving to cover, protect, decorate, or guide airflow. They are usually not core functional components of the vehicle (such as the engine or transmission), but are important components of the vehicle's appearance, aerodynamics, protection, and specific functions.

[0003] Currently, the machining of the shaft holes and straight holes on the outer cover is usually done by drilling and milling. When drilling and milling the shaft holes and straight holes on the outer cover, a clamping device is needed to clamp the outer cover securely. However, the clamping device used nowadays is mostly the common vise. When using vise to clamp the outer cover securely, it is difficult to control the clamping force of the vise. As a result, if the clamping force is slightly too large, the outer cover can easily be deformed, causing damage to the shape of the outer cover. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides an outer cover milling clamping device to solve the problem that when using vise to clamp and stabilize the outer cover, the clamping force of the vise is difficult to control, which easily deforms the outer cover when the clamping force is slightly too large, resulting in damage to the shape of the outer cover.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A milling and clamping device for an outer cover, comprising:

[0007] A substrate, wherein a boss is provided on the top of the substrate;

[0008] Mounting component, wherein the mounting component is disposed at the top center of the boss;

[0009] A clamping member is disposed on the top of the boss and located outside the periphery of the mounting member.

[0010] Based on the above technical solution, the present invention has made the following improvements:

[0011] Furthermore, the mounting component includes a cylinder and a stabilizing head. The cylinder is located at the top center of the boss, and a screw hole is provided at the top center of the cylinder. A stud is provided at the bottom center of the stabilizing head, and the stud on the stabilizing head is threaded into the screw hole on the cylinder. The stabilizing head is provided with an annular avoidance groove and a clearance hole.

[0012] Furthermore, the clamping component includes a displacement adjusting component and a clamping component. The displacement adjusting component includes guide rails, two of which are arranged opposite each other on the top of the boss and located outside the circumference of the cylinder. Two slide blocks are slidably arranged opposite each other between the two guide rails, and both slide blocks are located outside the circumference of the cylinder. Supports are provided on the top of the opposite side walls of the boss. A bidirectional screw is rotatably arranged between the two supports. The two slide blocks are respectively threaded onto the corresponding helical part of the bidirectional screw. A handwheel is provided at one end of the bidirectional screw.

[0013] Furthermore, the clamping component includes an assembly, and two assemblies are provided. The two assemblies are respectively disposed on corresponding slides and are both located outside the periphery of the cylinder. The opposing walls of the two assemblies are both arc-shaped, and multiple clamping blocks are detachably clamped on the arc-shaped walls of the two assemblies.

[0014] Furthermore, multiple mounting grooves are provided on both opposite side walls of the substrate.

[0015] The beneficial effects of this utility model are:

[0016] 1. By combining the base plate and mounting components, the base plate is mounted on the moving table of the milling machine during use. Then, the outer cover is placed on the mounting components to complete the initial placement and installation of the outer cover, so that the outer cover is initially installed on the base plate.

[0017] 2. By using the clamping components, after the outer cover is placed on the mounting component, the clamping components are used to clamp and stabilize the outer peripheral wall of the outer cover on the mounting component, so that the outer cover is stably installed on the substrate. Since the mounting component is located inside the outer cover, it can fill the inner cavity of the outer cover, thereby avoiding deformation of the outer cover and damage to its shape when the clamping components are used to clamp and stabilize the outer cover.

[0024] like Figures 1-3 As shown, an outer cover milling hole clamping device includes:

[0025] The substrate 101 has multiple mounting grooves 102 on its opposite side walls and a boss 103 on its top. In use, the substrate 101 is placed on the moving table of a milling machine or machining center. Then, the bottom end of the bolt is inserted into the slot in the moving table of the milling machine or machining center, so that the bolt is located in the mounting groove 102. Then, the nut is screwed in along the top end of the bolt, so that the bottom surface of the nut is tightly attached to the top surface of the substrate 101. The substrate 101 is mounted on the moving table of the milling machine or machining center by means of the bolt, nut, and mounting groove 102.

[0026] The mounting component is located at the top center of the boss 103. The mounting component includes a cylinder 201 and a stabilizing head 202. The cylinder 201 is located at the top center of the boss 103. A screw hole 203 is provided at the top center of the cylinder 201. A stud 204 is provided at the bottom center of the stabilizing head 202. The stud 204 on the stabilizing head 202 is screwed into the screw hole 203 on the cylinder 201, thereby realizing the detachable mounting of the stabilizing head 202 on the top of the cylinder 201. The stabilizing head 202 is provided with an annular avoidance groove 205 and a clearance hole 206. The annular avoidance groove 205 can play a role in avoiding the bottom of the milling cutter when milling the straight hole on the outer cover. The clearance hole 206 can play a role in avoiding the bottom of the drill bit when drilling the shaft hole on the outer cover.

[0027] In use, the outer cover is fastened onto the stabilizing head 202, thereby initially installing the outer cover onto the substrate 101; and since the stabilizing head 202 can be disassembled and replaced, different sizes of stabilizing heads 202 can be assembled on the top of the cylinder 201 to accommodate the initial placement and installation of outer covers of different sizes.

[0028] A clamping component is provided on the top of the boss 103 and located outside the periphery of the mounting component. The clamping component includes a displacement adjustment component and a clamping component. The displacement adjustment component includes two guide rails 301, which are arranged opposite to each other on the top of the boss 103 and outside the periphery of the cylinder 201. Two slide blocks 302 are slidably arranged opposite to each other between the two guide rails 301. Both slide blocks 302 are located outside the periphery of the cylinder 201. Supports 305 are provided on the top of the opposite side walls of the boss 103. A bidirectional screw 306 is rotatably arranged between the two supports 305. The two slide blocks 302 are respectively threaded onto the corresponding helical part of the bidirectional screw 306. A handwheel 307 is provided at one end of the bidirectional screw 306. By rotating the handwheel 307, the bidirectional screw 306 can be driven to rotate. When the bidirectional screw 306 rotates, the two slide blocks 302 can move synchronously on the guide rails 301.

[0029] The clamping component includes an assembly 303, of which two assemblies 303 are provided. The two assemblies 303 are respectively mounted on corresponding slides 302 and are located on the outer periphery of the cylinder 201. The opposing walls of the two assemblies 303 are both arc-shaped. Multiple clamping blocks 304 are detachably clamped on the arc-shaped walls of the two assemblies 303. When the two slides 302 move synchronously on the guide rail 301, the two assemblies 303 can be driven to move synchronously, causing each clamping block 304 to move and clamp on the outer peripheral wall of the outer cover. The assemblies 303 can be disassembled and replaced, so that assemblies 303 of different specifications and sizes can be assembled on the slides 302 to adapt to the clamping and stabilizing of the outer peripheral wall of the outer cover of different specifications and sizes.

[0030] In use, the outer cover is placed on the stabilizing head 202, which fills and supports the inside of the outer cover. Then, the handwheel 307 is turned to drive the bidirectional screw 306 to rotate. When the bidirectional screw 306 rotates, the two slides 302 move closer to each other on the guide rail 301, so that the corresponding clamping blocks 304 on the two assemblies 303 can clamp the outer cover on the outer peripheral wall, thereby clamping and stabilizing the outer cover on the cylinder 201, so that the outer cover is firmly installed on the base plate 101. Then, the straight holes and shaft holes on the outer cover can be drilled and milled. Since the stabilizing head 202 is supported inside the outer cover, the inner cavity of the outer cover can be filled, thus avoiding deformation of the outer cover and damage to its shape when clamping and stabilizing the outer cover with the clamping blocks 304.
