[0011] The utility model provides a multi-station fixture for a horizontal machining center, which has the following beneficial effects:

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0020] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0021] refer to Figure 1-4 The multi-station fixture of the horizontal machining center includes a machining table body 1, a slide groove 2 is provided on the upper end surface of the machining table body 1, a bidirectional threaded rod 3 is rotatably connected in the slide groove 2, and two first fixtures 4 are simultaneously threadedly connected to the surface of the bidirectional threaded rod 3, a through hole 7 is provided on the upper end surface of the machining table body 1, a second forward and reverse motor 11 is fixedly installed in the through hole 7, a gear 10 is installed at the output end of the second forward and reverse motor 11, and two racks 9 are meshed and connected to the surface of the gear 10 at the same time, and the upper end surfaces of the two racks 9 are fixedly connected to the second fixture 8.

[0022] By setting the second forward and reverse motor 11 and the gear 10, the second forward and reverse motor 11 can control the rotation of the gear 10 when working, and transmit the rack 9 through the gear 10. At the same time, the model of the second forward and reverse motor 11 is set to 5BLD120.

[0023] Furthermore, a first forward and reverse motor 6 is fixedly connected to the right side surface of the processing table body 1 , and the right end of the bidirectional threaded rod 3 passes through the side wall of the processing table body 1 and is installed in the output end of the first forward and reverse motor 6 .

[0024] By setting the first forward and reverse motor 6, when the first forward and reverse motor 6 is started, the first forward and reverse motor 6 can control the rotation of the bidirectional threaded rod 3, and the model is set to 5882-50ZY.

[0025] Furthermore, anti-skid pads 5 are fixedly connected to opposite sides of the two first clamps 4 , and the surfaces of the first clamps 4 are slidably connected in the slide groove 2 .

[0026] By providing the anti-skid pad 5 , when the anti-skid pad 5 is inserted into the workpiece, it not only clamps the workpiece on the left and right but also improves the stability of the clamping.

[0027] Furthermore, the two second clamps 8 are fixedly connected on opposite sides thereof with anti-slip grooves, and the surfaces of the second clamps 8 are slidably connected in the through holes 7 .

[0028] By providing the second clamp 8, when the second clamp 8 is pressed against the surface of the workpiece, the front and rear position limiting of the workpiece is achieved.

[0029] Furthermore, an anti-skid plate 14 is fixedly connected to the lower end surface of the processing table body 1 .

[0030] By providing the anti-skid plate 14, the processing table body 1 is made more stable when in use.

[0031] Furthermore, a limiting groove 12 is provided in the processing table body 1 , and a limiting rod 13 is fixedly connected to one side of the rack 9 , and a surface of the limiting rod 13 is slidably connected in the limiting groove 12 .

[0032] By providing the limiting groove 12 and the limiting rod 13 , when the rack 9 is driven, the limiting rod 13 will move horizontally along the inner wall of the limiting groove 12 , so that the gear 10 can drive the rack 9 more stably.

[0033] The working principle of the utility model is as follows: when in use, the staff will place the workpiece to be clamped and processed downward at the center of the processing table body 1, and then start the first forward and reverse motor 6 to control the rotation of the bidirectional threaded rod 3 in a clockwise manner, so that the clamping pad moves relatively and presses against the surface of the workpiece to complete the clamping of the workpiece. At the same time, when the force acting on the workpiece being processed is large, start the second forward and reverse motor 11 to rotate clockwise to realize the rotation of the gear 10. During the rotation, the gear 10 transmits the rack 9 to make the second clamp 8 move toward the middle along the inner wall of the through hole 7. When the second clamp 8 presses against the surface of the workpiece, the clamping of the workpiece is strengthened. By limiting the left, right, front and back positions of the workpiece, the deviation of the workpiece during processing is effectively avoided.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
