Description

Technical Field

[0001] This utility model relates to a foldable safety curtain for a horizontal machining center, belonging to the technical field of horizontal machining centers. Background Technology

[0002] A horizontal machining center is a CNC machine tool with a horizontal spindle. It is mainly used in the machining industry, such as automobile manufacturing, machine tool manufacturing, and mold making. It can complete the machining of small and medium-sized housings, valve bodies, and various complex parts. Its structure usually includes three linear motion axes and an optional fourth rotary axis. It is suitable for machining small and medium-sized housings, valve bodies, and various complex parts. This equipment has a CNC system, which can programmably control the machining process. The cutting tools require high rigidity and long life. Compared with vertical machining centers, horizontal machining centers have easier chip removal, but they are more difficult to debug and clamp.

[0003] Chinese Patent Publication No. CN 220971659 U discloses a modular machining center protective cover, comprising a first housing and a second housing, with a connecting mechanism between them. The connecting mechanism includes a connecting plate, snap-fit ​​blocks, a compression spring, and a pushing assembly. The connecting plate is fixedly connected to one side of the first housing, and a through groove is formed at the top of the second housing. The connecting plate is slidably inserted into the inner cavity of the through groove. Two snap-fit ​​blocks are slidably inserted into the inner cavity of the snap-fit ​​groove, and the pushing assembly is located inside a positioning groove. This invention utilizes the coordinated arrangement of the connecting plate, snap-fit ​​blocks, compression spring, and pushing assembly. By using the compression spring to snap-fit ​​the snap-fit ​​blocks, the first housing and the second housing can be quickly connected. When maintenance requires removing the machine tool, the first housing and the second housing can be directly disassembled by pushing the snap-fit ​​blocks with the pushing assembly, greatly facilitating the assembly and disassembly of the machine tool. The protective door of the above-mentioned device is a side-sliding door. When the width of the inlet and outlet on the front side of the machining center exceeds 50% of the width of the front side of the machining center, the side-sliding protective door will exceed the width of the front side of the machining center when it is opened. This makes it inconvenient to use in relatively narrow spaces, resulting in low flexibility and convenience of equipment use, and making it inconvenient for operators to use.

[0004] To address this, a foldable safety curtain for horizontal machining centers is proposed. Utility Model Content

[0005] In view of this, the present invention provides a foldable safety curtain for a horizontal machining center to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model is achieved as follows: a foldable safety curtain for a horizontal machining center, comprising: A machining center assembly includes a horizontal machining center body, with an inlet and outlet on the front side of the horizontal machining center body, and support columns fixedly installed on both the left and right sides of the bottom of the horizontal machining center body, with a base plate fixedly installed on the bottom of each of the four support columns. The protective assembly includes a drive motor and transmission bevel gears. The drive motor is fixedly installed on the right side of the top of the horizontal machining center body. The two transmission bevel gears are movably connected to the left and right sides of the top of the horizontal machining center body. The bottom of the two transmission bevel gears is fixedly connected to a bidirectional screw. The upper and lower sides of the surfaces of the two bidirectional screws are threaded with screw blocks. The front sides of the four screw blocks are movably connected to movable rods. The left and right sides of the front side of the horizontal machining center body are movably connected to bellows assemblies. The other ends of the two movable rods are movably connected to the front sides of the two bellows assemblies.

[0007] More preferably, the output end of the drive motor is fixedly connected to a connecting rod, and active bevel gears are fixedly installed on both the left and right sides of the surface of the connecting rod, with the surfaces of the two active bevel gears meshing with the surfaces of the two transmission bevel gears.

[0008] More preferably, the thread directions of the two bidirectional screw surfaces are the same, and the thread pitch of the two bidirectional screw surfaces is consistent with each other.

[0009] More preferably, the two bidirectional screws rotate in the same direction, and the threads on the inner surfaces of the four screw blocks match the threads on the upper and lower sides of the surfaces of the two bidirectional screws.

[0010] More preferably, the surfaces of the connecting rods are movably connected to support blocks via bearings, and the three support blocks are all fixedly installed on the top of the horizontal machining center body.

[0011] More preferably, limit rods are fixedly installed on both the left and right sides of the front side of the horizontal machining center body, and the two bidirectional screws are slidably connected to the surfaces of the two limit rods.

[0012] More preferably, anchor bolts are threaded to the front and rear sides of the top of the two base plates, and the bottoms of the four anchor bolts are threaded to the ground.

[0013] More preferably, observation windows are embedded on both the left and right sides of the horizontal machining center body, and the observation windows are made of tempered glass.

[0014] The present invention has the following advantages due to the adoption of the above technical solution: I. This utility model, by setting up a protective component, uses the output of a drive motor to cause a bidirectional screw to drive a movable rod to swing, thereby allowing the bellows assembly to unfold. This can block the inlet and outlet, preventing material debris from splashing and injuring operators during processing in the internal cavity of the horizontal machining center. At the same time, because the bellows assembly has a folding characteristic, it does not occupy much space when folded, making it easier for the entire equipment to be used in relatively narrow environments, improving the flexibility of equipment use and making it convenient for operators to use.

[0015] Second, this utility model provides support for the connecting rod by setting a support block, preventing it from falling off after prolonged use. A limiting rod limits the movement of the bidirectional screw, preventing it from rotating synchronously with the transmission bevel gear. Anchor bolts stabilize the entire equipment, preventing accidental collisions and shaking. An observation window allows operators to easily monitor the machining process of parts within the horizontal machining center's internal cavity, improving ease of use.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, this utility model embodiment provides a foldable safety curtain for a horizontal machining center, comprising: Machining center assembly 1 includes a horizontal machining center body 101. The front side of the horizontal machining center body 101 is provided with an inlet and outlet 102. Support columns 103 are fixedly installed on the left and right sides of the bottom of the horizontal machining center body 101. A base plate 104 is fixedly installed on the bottom of each of the four support columns 103. Protective component 2 includes a drive motor 201 and transmission bevel gears 204. The drive motor 201 is fixedly installed on the right side of the top of the horizontal machining center body 101. The two transmission bevel gears 204 are movably connected to the left and right sides of the top of the horizontal machining center body 101. A double-acting screw 205 is fixedly connected to the bottom of each of the two transmission bevel gears 204. Screw blocks 206 are threaded onto the upper and lower sides of the surfaces of the two double-acting screws 205. Movable rods 207 are movably connected to the front sides of the four screw blocks 206. Bellows plate assemblies 208 are movably connected to the left and right sides of the front of the horizontal machining center body 101. The other end of the movable rod 207 is movably connected to the front side of the two bellows plate assemblies 208. The output end of the drive motor 201 is fixedly connected to the connecting rod 202. The left and right sides of the surface of the connecting rod 202 are fixedly installed with active bevel gears 203. The surfaces of the two active bevel gears 203 mesh with the surfaces of the two transmission bevel gears 204. The thread directions of the surfaces of the two bidirectional screws 205 are the same. The thread spacing of the surfaces of the two bidirectional screws 205 is consistent with each other. The rotation directions of the two bidirectional screws 205 are the same. The threads on the inner surfaces of the four screw blocks 206 match the threads on the upper and lower sides of the surfaces of the two bidirectional screws 205.

[0023] By setting up the protective component 2, the output of the drive motor 201 causes the bidirectional screw 205 to drive the movable rod 207 to swing, thereby allowing the bellows assembly 208 to unfold. This can block the inlet and outlet 102, preventing material debris from splashing during processing in the inner cavity of the horizontal machining center body 101 and causing injury to the operator. At the same time, due to the folding characteristic of the bellows assembly 208, it does not occupy much space when folded, making it easier for the equipment to be used in relatively narrow environments, improving the flexibility of equipment use and making it more convenient for operators to use.

[0024] Example 2 like Figure 1-6 As shown, in one embodiment, the surfaces of the connecting rods 202 are movably connected to support blocks 209 via bearings. The three support blocks 209 are fixedly installed on the top of the horizontal machining center body 101. Limiting rods 210 are fixedly installed on the left and right sides of the front side of the horizontal machining center body 101. Two bidirectional screws 205 are slidably connected to the surfaces of the two limiting rods 210. Anchor bolts 106 are threadedly connected to the front and rear sides of the top of the two base plates 104. The bottoms of the four anchor bolts 106 are threadedly connected to the ground. Observation windows 105 are embedded on the left and right sides of the horizontal machining center body 101. The material of the observation windows 105 is tempered glass.

[0025] By setting the support block 209, the connecting rod 202 can be supported, preventing it from falling off after long-term use. By setting the limit rod 210, the movement of the bidirectional screw 205 can be limited, preventing it from rotating synchronously with the transmission bevel gear 204. By setting the anchor bolts 106, the overall equipment can be stabilized, preventing accidental collisions that could cause the equipment to shake. By setting the observation window 105, the operator can easily observe the processing status of the parts inside the horizontal machining center body 101, improving the ease of use of the equipment.

[0026] In operation, when it is necessary to shield the inlet / outlet 102, the output of the drive motor 201 causes the connecting rod 202 to rotate the active bevel gear 203. The active bevel gear 203 and the transmission bevel gear 204 cooperate with each other, causing the transmission bevel gear 204 to drive the bidirectional screw 205 to rotate synchronously. At this time, the screw block 206 moves inward. The screw block 206 cooperates with the movable rod 207, causing the movable rod 207 to drive the bellows assembly 208 to move inward, thereby unfolding the bellows assembly 208 to shield the inlet / outlet 102. 02. When the horizontal machining center body 101 needs to be loaded or unloaded, the drive motor 201 reverses the output, and the connecting rod 202 drives the active bevel gear 203 to rotate. The active bevel gear 203 and the transmission bevel gear 204 cooperate again, causing the transmission bevel gear 204 and the bidirectional screw 205 to rotate in opposite directions. At this time, the screw block 206 moves outward, which in turn causes the movable rod 207 to drive the bellows assembly 208 to move outward, causing the bellows assembly 208 to fold and retract, thereby removing the obstruction and protection of the inlet and outlet 102.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
