All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] Reference Figures 1 to 4 As shown, the utility model provides a noise reduction protective door for a machine tool, comprising two door bodies 1, a seal is arranged between the two door bodies 1, a noise reduction assembly is arranged inside the door body 1, a plurality of pulleys 4 are fixedly installed at equal intervals on the top of the door body 1, a guide rod 5 and a slide rod 6 are fixedly installed on the top of the machine tool housing, the guide rod 5 and the slide rod 6 are arranged in parallel, the pulley 4 is slidably arranged between the guide rod 5 and the slide rod 6, the two door bodies 1 are symmetrically slidably arranged on the slide rod 6, a driving assembly is fixedly installed on the bottom of the machine tool housing, and the two door bodies 1 are synchronously opened and closed by the driving assembly.
[0025] The noise reduction component arranged in the door body 1 can effectively reduce the noise when processing products in the machine tool;
[0026] The drive assembly can be used to simultaneously and synchronously move the two door bodies 1 toward each other or away from each other, that is, to open and close the machine tool protection door, which is convenient for taking and placing workpieces and plays a role in safety protection for the operation, preventing metal chips and cutting fluid from splashing;
[0027] The sealing member is provided to further improve the sealing performance of the two door bodies 1 after closing, thereby preventing noise from being transmitted from between the two door bodies 1 .
[0028] Furthermore, the driving assembly includes two fixed seats 7 fixedly installed on the bottom of the machine tool housing, a bidirectional threaded rod 8 is rotatably connected between the two fixed seats 7, a motor 10 is fixedly installed on the machine tool housing, the output end of the motor 10 is fixedly connected to one end of the bidirectional threaded rod 8, and an emergency assembly is fixedly installed on the other end of the bidirectional threaded rod 8. Both ends of the bidirectional threaded rod 8 are threadedly connected with sliders 9, and the two sliders 9 are symmetrically arranged, and the sliders 9 are fixedly installed in the middle of the bottom end of the corresponding door body 1.
[0029] The motor 10 is provided to drive the bidirectional threaded rod 8 to rotate, and the rotation of the bidirectional threaded rod 8 drives the slider 9 to move, so that the slider 9 drives the door body 1 to move on the slide rod 6. By controlling the speed and direction of the motor 10, the opening and closing of the two door bodies 1 are realized.
[0030] Furthermore, the emergency component includes a limit column 12 fixedly mounted on the end of the bidirectional threaded rod 8 away from the motor 10, a sleeve 13 is sleeved on the limit column 12, one end of the sleeve 13 is provided with a groove, the groove is limitedly matched with the limit column 12, and the other end of the sleeve 13 is fixedly connected to a handle 14.
[0031] In this embodiment, the limit column 12 is a triangular structure, and the groove formed in the sleeve 13 is a triangular groove matching the limit column 12. When not in use, the sleeve 13 and the handle 14 are removed from the limit column 12 to avoid adding load to the motor 10 and to avoid the sleeve 13 and the handle 14 being thrown out when the bidirectional threaded rod 8 rotates. The sleeve 13 and the limit column 12 are driven to rotate by rotating the handle 14, thereby realizing the rotation of the bidirectional threaded rod 8, thereby realizing manual opening and closing of the two door bodies 1. This can prevent the problem that the machine tool cannot drive the bidirectional threaded rod 8 to rotate through the motor 10 due to an abnormality, and the door cannot be opened or closed.
[0032] Furthermore, the noise reduction component includes sound-absorbing cotton 16 and two sound insulation boards 17 . The door body 1 is a hollow structure. The two sound insulation boards 17 are respectively fixedly installed on the inner walls on both sides of the door body 1 , and the sound-absorbing cotton 16 is filled between the two sound insulation boards 17 .
[0033] In this embodiment, the sound insulation board 17 is a lead plate with a thickness of 2mm-4mm. The sound insulation board 17 is fixed to the inner wall of the door body 1 by screws, which can effectively reduce resonance and thus effectively reduce the transmission of sound. The sound-absorbing cotton 16 can further absorb the noise processed by the sound insulation board 17 to play a sound-absorbing role.
[0034] Furthermore, the sealing member includes a sealing block 18 and a sealing block 19, which are respectively fixedly installed on opposite sides of the two door bodies 1, and the sealing block 18 is a concave structure, and a sealing gasket is attached to the groove of the sealing block 18, and the sealing block 19 is a convex structure, and the sealing block 19 is adapted to the sealing block 18, and the sealing block 18 and the sealing block 19 are arranged in parallel along the vertical direction of the door body 1, and the lengths of the sealing block 18 and the sealing block 19 are equal to the height of the door body 1.
[0035] By setting the sealing block 1 18 and the sealing block 2 19 into a "concave-convex" structure, the two door bodies 1 can fit more firmly. At the same time, a sealing gasket is attached to the groove of the sealing block 18 to perform a sealing function, thereby reducing the decibel of noise transmitted from between the two door bodies 1.
[0036] Furthermore, a handle 3 is fixedly mounted on one end of the door body 1 close to the sealing member.
[0037] The handle 3 is provided to facilitate the operator to assist the emergency assembly to open the door body 1.
[0038] Furthermore, in order to improve the sealing between the door body 1 and the machine tool housing, a sealing strip 11 is provided between the door body 1 and the machine tool housing. The sealing strip 11 is fixedly mounted on the door body 1. In the present embodiment, the sealing strip 11 is a rubber sealing strip. After being extruded, the rubber strip has a certain rebound force, so that the rubber strip fits tightly against the machine tool housing.
[0039] Furthermore, in order to prevent people's hands or workpieces from being pinched when the two doors 1 are closed, a grating 15 is fixedly installed on one end of the door 1 close to the seal, and a controller is fixedly installed on the machine tool housing. The grating 15 and the motor 10 are electrically connected to the controller.
[0040] Furthermore, in order to facilitate the operator to observe and understand the internal operation of the machine tool, an observation window 2 is provided on the door body 1, and a transparent plate is fixedly provided on the observation window 2. In the present embodiment, the transparent plate is an acrylic transparent plate.
[0041] The noise reduction protective door for machine tools provided by the utility model has the following working principle: when in use, the controller button is pressed, the motor 10 drives the two-way threaded rod 8 to rotate, the two-way threaded rod 8 rotates and drives the slider 9 to move, and then the slider 9 drives the door body 1 to move on the slide rod 6, and the opening and closing of the two door bodies 1 are realized by controlling the speed and direction of the motor 10, which is convenient for the operator to take and place the workpiece. When the machine tool is abnormal and the two-way threaded rod 8 cannot be driven to rotate by the motor 10, resulting in the inability to open and close the door, the sleeve 13 and the limit column 12 can be driven to rotate by rotating the handle 14, thereby realizing the rotation of the two-way threaded rod 8, thereby realizing manual opening and closing of the two door bodies 1.
[0042] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
