Description

Technical Field

[0001] This utility model relates to the field of machine tool protection technology, and in particular to a protective sheet metal device for a dual-spindle head wheel hub machining center. Background Technology

[0002] Machine tools are machines used to manufacture machinery and equipment. They play a vital role in the modernization of the national economy. External protection for machine tools is an important component, effectively protecting the equipment and the safety of operators. Different types of machine tools require different external protection measures. For example, a twin-spindle head hub machining center uses sheet metal external protection to safeguard operators and prevent metal shavings from flying.

[0003] A search revealed a patent with publication number CN215432782U entitled "A Sheet Metal Housing for Machine Tool Protection." The patent addresses the technical problem that machine tools may be subjected to external impacts during use. Excessive impact force can damage internal equipment. By incorporating shock-absorbing mechanisms and protective plates, the internal equipment can be effectively protected, preventing direct impact from external forces. However, the following drawbacks remain: the protective sheet metal is typically fixed to the machine tool with screws or welding, which can deform and wear over time, making quick disassembly and replacement impossible. Furthermore, the protective sheet metal is prone to localized deformation under the impact of metal filings inside the machine tool. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective sheet metal device for a dual-spindle head hub machining center.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective sheet metal device for a dual-spindle head wheel hub machining center includes a machine frame. Shock-absorbing support feet are fixedly installed at the four corners of the bottom of the machine frame. Support members are inserted into the four corners of the top of the machine frame, and top frames are inserted into the top of the four support members. Multiple equidistant first inserts are fixedly installed on the outer walls of opposite ends of every two adjacent support members. A rectangular plate is fixedly installed on the outer walls of opposite ends of every two adjacent support members. Sheet metal parts are snapped onto the outer sides of every two adjacent support members. A second insertion hole is opened on the opposite side of every two adjacent rectangular plates. A fixing frame is fixedly installed at the upper and lower ends of the outer wall of each support member, and rotating frames are rotatably installed on both sides of the fixing frame. A U-shaped pull rod is slidably inserted into the outer side of the rotating frame. An extrusion plate is fixedly installed between the two ends of the pull rod. Two support springs are fixedly connected between the extrusion plate and the opposite ends of the rotating frame, and the two support springs are respectively sleeved on both ends of the pull rod.

[0007] Preferably, a cap is snapped onto the top center of the top frame, a rectangular frame is fixedly installed at the bottom of the top frame, a heat-absorbing fan is fixedly installed at the bottom of the cap, and a negative pressure pipe is fixedly installed at the output end of the heat-absorbing fan.

[0008] Preferably, the support member has inserts at both the top and bottom.

[0009] Preferably, the sheet metal part is composed of an outer plate and an inner plate fixedly connected together, and the outer plate has first insertion holes on both sides, the inner plate has multiple second insertion rods fixedly installed on both sides of the inner wall, and rubber strips are fixedly installed on both sides of the inner plate.

[0010] Preferably, the first socket is matched with the first plug rod, and the second socket is matched with the second plug rod.

[0011] Preferably, the two fixing brackets and the tie rods in each column are perpendicular to the diagonal of the support.

[0012] Preferably, the length of the first insert is greater than the thickness of the outer plate, and the end of the first insert is located on the outer side of the outer wall of the sheet metal part.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model proposes a protective sheet metal device for a dual-spindle head wheel hub machining center. Support members are inserted at the four corners of the machine tool frame top, and top frames are inserted at the top of the four support members. A first insertion hole connects to a first insertion rod, and a second insertion hole connects to a second insertion rod. This allows sheet metal parts to be secured to the outer sides of every two adjacent support members, thus forming a sheet metal protective cover at the top of the machine tool frame to protect the operator's safety and prevent metal filings from flying. The length of the first insertion rod is greater than the thickness of the outer plate, so that the end of the first insertion rod is located on the outer side of the sheet metal part's outer wall. The rotating frame is then rotated to be parallel to the sheet metal part, and a pull rod is pulled outwards, causing the extrusion plate to approach the rotating frame until the rotating frame engages with the first insertion rod. Releasing the pull rod causes two support springs to extend, pressing the extrusion plate tightly against the circumferential outer walls of the multiple first insertion rods, thereby fixing and limiting the sheet metal part to the outer side of the two support members. This facilitates quick installation and disassembly, and also allows for partial disassembly of the device based on deformation conditions.

[0015] 2. The present invention proposes a protective sheet metal device for a dual-spindle head hub machining center. The device is equipped with negative pressure pipes and heat absorption fans at the top and bottom of the top frame, which helps to transfer heat inside the sheet metal protective cover and also helps the sheet metal protective cover to dissipate heat in time. The sheet metal parts are composed of an outer plate and an inner plate fixedly connected, and rubber strips are fixedly installed on both sides of the inner plate to buffer the impact of flying metal fragments on the sheet metal parts when the machine tool processes the workpiece.

Detailed Implementation

[0022] Reference Figure 1-5 A protective sheet metal device for a dual-spindle head wheel hub machining center includes a machine frame 1. Shock-absorbing support feet are fixedly installed at the four corners of the bottom of the machine frame 1. Support members 2 are inserted into the four corners of the top of the machine frame 1, and top frames 7 are inserted into the top of the four support members 2. Multiple equidistant first inserts 4 are fixedly installed on the outer walls of opposite ends of every two adjacent support members 2. Rectangular plates 5 are fixedly installed on the outer walls of opposite ends of every two adjacent support members 2. Sheet metal parts 12 are snapped onto the outer sides of every two adjacent support members 2. A second insertion hole 6 is provided on the opposite side of each pair of adjacent rectangular plates 5. A fixing frame 18 is fixedly installed on the upper and lower ends of the outer wall of each support member 2, and a rotating frame 19 is rotatably installed on both sides of the fixing frame 18. A pull rod 20 is slidably inserted on the outside of the rotating frame 19, and the pull rod 20 is U-shaped. An extrusion plate 21 is fixedly installed between the two ends of the pull rod 20. Two support springs 22 are fixedly connected between the extrusion plate 21 and the opposite end of the rotating frame 19, and the two support springs 22 are respectively sleeved on both ends of the pull rod 20.

[0023] In this utility model, a cover 8 is snapped into the top middle of the top frame 7, a rectangular frame 11 is fixedly installed at the bottom of the top frame 7, a heat absorption fan 9 is fixedly installed at the bottom of the cover 8, and a negative pressure pipe 10 is fixedly installed at the output end of the heat absorption fan 9.

[0024] The support member 2 has inserts 3 at both the top and bottom;

[0025] The sheet metal part 12 is formed by a fixed connection between an outer plate 16 and an inner plate 13. The outer plate 16 has first insertion holes 17 on both sides. Multiple second insertion rods 14 at equal intervals are fixedly installed on both sides of the inner wall of the inner plate 13. Rubber strips 15 are fixedly installed on both sides of the inner plate 13.

[0026] The first socket 17 is matched with the first plug rod 4, and the second socket 6 is matched with the second plug rod 14.

[0027] The two fixed brackets 18 and the tie rods 20 in each column are perpendicular to the diagonal of the support member 2;

[0028] The length of the first insert 4 is greater than the thickness of the outer plate 16, and the end of the first insert 4 is located on the outer side of the outer wall of the sheet metal part 12.

[0029] Working principle: Support members 2 are inserted into the four corners of the top of the machine tool frame 1, and top frames 7 are inserted into the top of the four support members 2. The first insertion hole 17 is inserted into the first insertion rod 4, and the second insertion hole 6 is inserted into the second insertion rod 14. This allows sheet metal parts 12 to be snapped onto the outside of every two adjacent support members 2, thus forming a sheet metal protective cover at the top of the machine tool frame 1 to protect the safety of the operator and prevent iron filings from flying. The length of the first insertion rod 4 is greater than the thickness of the outer plate 16, so that the end of the first insertion rod 4 is located on the outside of the outer wall of the sheet metal part 12. Then, the rotating frame 19 is rotated to be parallel to the sheet metal part 12, and the pull rod 20 is pulled outward to bring the extrusion plate 21 close to the rotating frame 19 until the rotating frame 19 is sleeved with the first insertion rod 4. The pull rod 20 is released, and the two support springs 22 pop out and extend, so that the extrusion plate 21 presses tightly against the outer circumference of multiple first insertion rods 4, thereby fixing and limiting the sheet metal part 12 to the outside of the two support members 2. This facilitates quick installation and disassembly, and also makes it easy to disassemble the device locally according to the deformation.

[0030] The top frame 7 is equipped with negative pressure pipes 10 and heat absorption fans 9 at its upper and lower ends, which helps to transfer the heat inside the sheet metal protective cover and also helps the sheet metal protective cover to dissipate heat in time. The sheet metal part 12 is formed by the outer plate 16 and the inner plate 13 being fixedly connected. Rubber strips 15 are fixedly installed on both sides of the inner plate 13 to buffer the impact of flying metal chips on the sheet metal part 12 when the machine tool processes the workpiece.
