[0022] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] As Figures 1 to 3 shown, this embodiment provides a clamping fixture for an inclined ejector part, which includes a clamping device 1 and an angle spacer 2. The clamping device 1 is used to clamp the inclined ejector part 4. The angle spacer 2 is installed in the clamping device 1 and the angle spacer 2 is used to support the inclined ejector part 4 to adjust the machining angle of the inclined ejector part 4. A limiting structure for restricting the movement of the angle spacer 2 is provided between the angle spacer 2 and the clamping device 1.
[0024] In the clamping fixture for the inclined ejector part in this embodiment, the machining angle of the inclined ejector part 4 is adjusted by the angle spacer 2, and the inclined ejector part 4 after angle adjustment is clamped by the clamping device 1, avoiding the looseness of the inclined ejector part 4 due to the lack of freedom constraint on the bottom surface, easily realizing the positioning and clamping work of the inclined ejector part 4, achieving the purpose of stably and reliably clamping the inclined ejector part 4, reducing the clamping difficulty and improving the clamping efficiency.
[0025] In this embodiment, the bottom surface of the angle spacer 2 is a reference surface 21, and the top surface of the angle spacer 2 is an inclined surface 22 for supporting the inclined ejector part 4. An adjustment angle a is formed between the inclined surface 22 and the reference surface 21. The setting of the angle spacer 2 can not only adjust the machining angle of the inclined ejector part 4, prevent the inclined ejector part 4 from loosening during the clamping process, make the clamping of the inclined ejector part 4 more stable and reliable, but also buffer the vibration generated during rough machining, make the machining more stable. At the same time, the angle spacer 2 can also reduce the direct friction between the clamping device 1 and the inclined ejector part 4, effectively extending the service life of the clamping device 1.
[0026] In this embodiment, the angle spacer 2 is provided with multiple specifications such as 5°, 10°, 15°, etc. according to the size of the adjustment angle a. The operator can select the corresponding specification of the angle spacer 2 according to the requirements of the inclined ejector part 4 for machining angle adjustment. Of course, other specifications of the angle spacer 2 can also be set, and this embodiment does not limit this.
[0027] In this embodiment, the limiting structure is arranged on the angle spacer 2, and the limiting of the angle spacer 2 is realized by the cooperation of the limiting structure and the clamping device 1. In practical applications, the limiting structure can also be arranged on the clamping device 1, and this embodiment does not limit this. By setting the limiting structure, the movement of the angle spacer 2 can be prevented during the process of the clamping device 1 clamping the inclined ejector part 4, improving the stable reliability of the clamping of the inclined ejector part 4.
[0028] Preferably, the limiting structure is arranged at the lower end of the angle spacer 2.
[0029] Specifically, the limiting structure is a limiting pin 5. The angle cushion block 2 is provided with an insertion hole penetrating through the angle cushion block 2. The limiting pin 5 is inserted into the insertion hole and both ends thereof respectively extend out of the insertion hole to form limiting portions, and the two limiting portions abut against the side portion of the clamping device 1 (as shown in Figure 1 and Figure 2 shown); of course, the limiting structure can also adopt other structures. For example, a limiting post is provided on the clamping device 1, and a limiting hole adapted to the limiting post is provided on the angle cushion block 2. During use, the angle cushion block 2 is sleeved on the limiting post through the limiting hole to realize the positioning of the angle cushion block 2, which is specifically set according to actual requirements, and this embodiment does not limit this.
[0030] The clamping device 1 in this embodiment includes a base 11, a limiting member 12 fixedly arranged on the base 11, a clamping member 13 slidably arranged on the base 11, and a driving member for driving the clamping member 13 to move towards the direction where the limiting member 12 is located. The clamping member 13 is used to cooperate with the limiting member 12 to clamp the angled ejector part 4. With such a setting, the structure of the clamping device 1 is simplified and the cost is saved.
[0031] In order to improve the linearity of the movement of the clamping member 13 and ensure the clamping effect, a sliding guiding structure is arranged between the clamping member 13 and the base 11 in this embodiment.
[0032] Specifically, the sliding guiding structure is a linear slide rail. The linear slide rail is arranged on the base 11, and the clamping member 13 is arranged on the slider of the linear slide rail.
[0033] A support member 15 is arranged on the base 11 in this embodiment. The driving member is a screw rod 14 threadedly connected to the support member 15. One end of the screw rod 14 passes through the support member 15 and abuts against the clamping member 13. In practical applications, the driving member can be replaced by a cylinder. During installation, only the cylinder is installed on the base 11, and the clamping member 13 is connected to the piston rod of the cylinder. The driving member can be specifically selected according to actual requirements, and this embodiment does not limit this.
[0034] A hand wheel (not shown in the figure) is arranged at one end of the screw rod 14 away from the clamping member 13 in this embodiment. With such a setting, the convenience of operating the screw rod 14 is improved.
[0035] In order to improve the connection strength, the base 11, the limiting member 12 and the support member 15 are integrally arranged in this embodiment. Of course, a split structure can also be adopted, and this embodiment does not limit this.
[0036] In order to meet the processing height requirements of the angled ejector part 4, the angled ejector part clamping fixture in this embodiment further includes a height cushion block 3 for adjusting the height of the angled ejector part 4.
[0037] In this embodiment, the height shims 3 are provided in various specifications such as 2 cm, 4 cm, 6 cm, etc. according to the size of the adjusted height h. The operator can select the corresponding height shims 3 according to the machining height requirements of the lifter part 4 to adjust the machining height. Of course, the height shims 3 can also be set in other specifications, and this embodiment does not limit this.
[0038] During use, first place the angle shim 2 on the base 11 so that the angle shim 2 is located between the clamping member 13 and the limiting member 12. At the same time, place the limit pin 5 on the sides of the clamping member 13 and the limiting member 12. Then place the lifter part 4 on the angle shim 2. Finally, manually rotate the handwheel so that the screw 14 drives the clamping member 13 to move linearly until the clamping member 13 and the limiting member 12 cooperate to clamp the lifter part 4.
[0039] Since the top surface of the angle shim 2 is an inclined surface 22, during the process of clamping the lifter part 4, the angle shim 2 will move towards the direction where the higher end of the angle shim 2 is located, and the two limiting parts of the limit pin 5 will automatically abut against the sides of the limiting member 12 and the clamping member 13. Therefore, during the clamping process, there is no need to adjust the position of the limit pin 5, which further saves the clamping time and improves the clamping efficiency.
[0040] The height shims 3 can be selected whether to be used according to the clamping requirements of the lifter part 4. If used, only place the height shims 3 under the angle shim 2.
[0041] The above has introduced in detail the structure and usage method of the clamping fixture for the lifter part of the present utility model. Compared with the prior art, the clamping fixture for the lifter part of the present utility model can stably and reliably clamp the lifter part 4, greatly reducing the clamping difficulty and improving the clamping efficiency.
[0042] The present utility model is not limited to the above specific embodiments. All kinds of transformations made by those of ordinary skill in the art starting from the above concepts without creative labor fall within the protection scope of the present utility model.
