Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a clamping and fixing device for machining. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment; during machining, a fixing device is needed to hold the workpiece in place.

[0003] The current clamping and fixing mechanisms generally have a limited fixing method, which can only fix the workpiece in the horizontal or vertical direction. This makes it impossible to adjust the fixing direction appropriately according to the shape of the workpiece, resulting in certain limitations and inconveniences.

[0004] Therefore, this application proposes a clamping and fixing device for machining to solve the problems in the prior art.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping and fixing device for machining.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A clamping and fixing device for machining includes a base plate, a machined part, and a fixing mechanism;

[0009] The base plate is provided with a processing table, and the processing table is provided with machined parts. The base plate is provided with two fixing mechanisms, and the two fixing mechanisms are respectively corresponding to the machined parts.

[0010] The fixing mechanism includes a first hydraulic cylinder, an arc-shaped plate, a slider, a second hydraulic cylinder, a transmission rod, a sleeve, a worm gear, a motor, and a worm. Two first hydraulic cylinders are fixedly mounted on the base plate. The output end of the first hydraulic cylinder is rotatably connected to the arc-shaped plate, and the slider is slidably connected to the arc-shaped plate. The second hydraulic cylinder is fixedly mounted on the slider, and the output end of the second hydraulic cylinder is fixedly mounted with a pressure plate. The pressure plate corresponds to the machined part. Through the cooperative design between the base plate, the processing table, the bracket, and the fixing mechanism, the second hydraulic cylinder can be adjusted in multiple directions according to the actual situation. Furthermore, the cooperation of the pressure plate can achieve the effect of squeezing the machined part in multiple directions, greatly improving flexibility and practicality.

[0011] Preferably, a transmission rod is fixedly connected to one end of the arc-shaped plate, and a sleeve is slidably sleeved on the transmission rod. A bracket is installed on the processing table, and the sleeve is rotatably connected to the bracket. Through the functions of the sleeve, bracket, and transmission rod, the arc-shaped plate can be guided, so as to facilitate the motor to rotate the arc-shaped plate to a certain angle.

[0012] Preferably, a worm gear is fixedly fitted at one end of the sleeve, a worm is meshed on the worm gear, and fixed blocks are rotatably connected to both ends of the worm. Both fixed blocks are fixedly connected to the bracket, and a motor is fixedly installed on the bracket. The output end of the motor is fixedly connected to one end of the worm. Driven by the motor, the worm rotates on the two fixed blocks and transmits power to the worm gear, causing the worm gear to drive the sleeve to rotate a certain angle from the bracket.

[0013] Preferably, the processing table has two movable slots, which correspond to the two arc-shaped plates respectively. The two movable slots facilitate the movement and adjustment of the arc-shaped plates and the hydraulic cylinder.

[0014] Preferably, the arc-shaped plate has a sliding groove, and the slider slides within the sliding groove. Multiple limiting grooves are provided on both sides of the arc-shaped plate. Two insertion holes are provided at each end of the slider, corresponding to the multiple limiting grooves. Four identical limiting rods are installed in the four insertion holes and the corresponding four limiting grooves. By sliding the slider within the sliding groove on the arc-shaped plate, the tilt angle of the second hydraulic cylinder can be adjusted. Simultaneously, the two insertion holes on both sides of the slider correspond to four of the multiple limiting grooves. Then, the four limiting rods are installed into the four insertion holes, thereby limiting the slider. This achieves the effect of adjusting the extrusion direction of the second hydraulic cylinder on the machined workpiece.

[0015] Preferably, a groove is provided on one side of the transmission rod, and a protrusion is welded to the inner side of the sleeve. The protrusion slides in the groove. Through the interaction between the protrusion on the inner side of the sleeve and the groove, the sleeve drives the transmission rod to rotate synchronously by a certain angle, and the transmission rod can slide in the sleeve.

[0016] Preferably, the output end of the hydraulic cylinder is fixedly fitted with a bearing, and the outer wall of the bearing is fixedly connected to the arc-shaped plate to facilitate the rotation of the arc-shaped plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a clamping and fixing device for machining, see reference. Figures 1-4 A clamping and fixing device for machining includes a base plate 1, a machined part 3, and a fixing mechanism 5;

[0027] A processing table 2 is provided on the base plate 1, and a machined part 3 is provided on the processing table 2. Two fixing mechanisms 5 are provided on the base plate 1, and the two fixing mechanisms 5 are corresponding to the machined part 3.

[0028] The fixing mechanism 5 includes a hydraulic cylinder 51, an arc plate 52, a slider 53, a hydraulic cylinder 54, a transmission rod 55, a sleeve 56, a worm gear 57, a motor 58, and a worm 59. Two hydraulic cylinders 51 are fixedly installed on the base plate 1. The output end of the hydraulic cylinder 51 is rotatably connected to the arc plate 52, and the slider 53 is slidably connected to the arc plate 52. The hydraulic cylinder 54 is fixedly installed on the slider 53. A pressure plate 6 is fixedly installed on the output end of the hydraulic cylinder 54. The pressure plate 6 is fixedly installed on the output end of the hydraulic cylinder 54 by bolts, which facilitates the replacement of the pressure plate 6. An anti-slip pad is fixedly installed on one side of the pressure plate 6 to increase the friction between the pressure plate 6 and the machined part 3. The pressure plate 6 corresponds to the machined part 3. Through the cooperative design between the base plate 1, the processing table 2, the bracket 4, and the fixing mechanism 5, the hydraulic cylinder 54 can be adjusted in multiple directions according to the actual situation. Furthermore, with the cooperation of the pressure plate 6, the machined part 3 can be squeezed in multiple directions, which greatly improves the flexibility and practicality.

[0029] In this embodiment, a transmission rod 55 is fixedly connected to one end of the arc plate 52, and a sleeve 56 is slidably sleeved on the transmission rod 55. A bracket 4 is installed on the processing table 2, and the sleeve 56 is rotatably connected to the bracket 4. Through the functions of the sleeve 56, the bracket 4 and the transmission rod 55, the arc plate 52 can be guided, so that the motor 58 can drive the arc plate 52 to rotate at a certain angle. A bearing 2 is fixedly sleeved on the sleeve 56, and the outer wall of the bearing 2 is fixedly connected to the bracket 4.

[0030] In this embodiment, a worm gear 57 is fixedly sleeved on one end of the sleeve 56, and a worm 59 is meshed on the worm gear 57. Both ends of the worm 59 are rotatably connected to fixed blocks, and both fixed blocks are fixedly connected to the bracket 4. A motor 58 is fixedly installed on the bracket 4, and the output end of the motor 58 is fixedly connected to one end of the worm 59. Driven by the motor 58, the worm 59 rotates on the two fixed blocks and transmits power to the worm gear 57, so that the worm gear 57 drives the sleeve 56 to rotate a certain angle from the bracket 4.

[0031] In this embodiment, the processing table 2 has two movable slots, which correspond to two arc-shaped plates 52 respectively. The two movable slots facilitate the movement and adjustment of the arc-shaped plates 52 and the hydraulic cylinder 54.

[0032] In this embodiment, a sliding groove is provided on the arc plate 52, and the slider 53 slides in the sliding groove. Multiple limiting grooves 8 are provided on both sides of the arc plate 52. Two insertion holes are provided at both ends of the slider 53, which correspond to the multiple limiting grooves 8 respectively. Four identical limiting rods 7 are installed in the four insertion holes and the four corresponding limiting grooves 8. By sliding the slider 53 in the sliding groove on the arc plate 52, the tilt angle of the hydraulic cylinder 2 54 can be adjusted. At the same time, the two insertion holes on both sides of the slider 53 correspond to four of the multiple limiting grooves 8 respectively. Then, the four limiting rods 7 are installed into the four insertion holes, thereby achieving the effect of limiting the slider 53. This achieves the effect of adjusting the extrusion direction of the hydraulic cylinder 2 54 on the machined part 3.

[0033] In this embodiment, a groove 9 is provided on one side of the transmission rod 55, and a protrusion is welded to the inner side of the sleeve 56. The protrusion slides in the groove 9. Through the interaction between the protrusion on the inner side of the sleeve 56 and the groove 9, the sleeve 56 drives the transmission rod 55 to rotate synchronously by a certain angle, and the transmission rod 55 can slide in the sleeve 56.

[0034] In this embodiment, the output end of the hydraulic cylinder 51 is fixedly fitted with a bearing, and the outer wall of the bearing is fixedly connected to the arc plate 52 to facilitate the rotation of the arc plate 52.

[0035] Working principle: When in use, firstly, the machined part 3 is placed on the processing table 2 and positioned between the two fixing mechanisms 5. Then, the extension drive of the hydraulic cylinder 2 54 causes the pressure plate 6 to move toward the machined part 3 and abut against it, thereby achieving the effect of clamping and fixing the machined part 3.

[0036] By sliding the slider 53 within the sliding groove on the arc plate 52, the tilt angle of the hydraulic cylinder 54 can be adjusted. Simultaneously, the two insertion holes on both sides of the slider 53 correspond to four of the multiple limiting grooves 8. Then, four limiting rods 7 are installed into the four insertion holes, thereby limiting the slider 53. This, in turn, adjusts the pressing direction of the hydraulic cylinder 54 on the machined part 3.

[0037] Driven by hydraulic cylinder 51, the arc plate 52 can move up and down a certain distance, thereby achieving the effect of adjusting the height of hydraulic cylinder 54, which further facilitates the fixing of the machined part 3 by hydraulic cylinder 54.

[0038] Driven by the motor 58, the worm 59 rotates on the two fixed blocks and transmits power to the worm wheel 57. The worm wheel 57 drives the sleeve 56 to rotate from the bracket 4 by a certain angle. At the same time, through the interaction between the protrusion and the groove 9 on the inner side of the sleeve 56, the sleeve 56 drives the transmission rod 55 to rotate synchronously by a certain angle. Meanwhile, through the transmission of the arc plate 52 and the slider 53, the hydraulic cylinder 54 rotates by a certain angle, thereby further facilitating the fixing of the machined part 3 by the hydraulic cylinder 54.

[0039] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, the machined parts can be squeezed and fixed in three directions, improving convenience and flexibility, and the structure is simple and more practical.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
