Description

Technical fields:

[0001] This utility model relates to the field of machining fixture technology, and specifically to a machining fixture for shock absorber towers. Background technology:

[0002] The core function of a workpiece fixture is to fix the workpiece and ensure its correct position during machining or inspection, while improving machining accuracy and efficiency.

[0003] To ensure the precise position of the workpiece within the fixture and eliminate workpiece uncertainty during machining, a fixture is typically used to quickly position the workpiece using standardized components. This aligns the machining datum with the machine tool spindle center, reducing human error.

[0004] Currently available clamps include, for example, a thin-walled support anti-deformation hydraulic clamp disclosed in Chinese invention patent application CN112122973A, which includes: a base, a support mounted on the base, a positioning plate mounted on one side of the support, a first positioning pin, a second positioning pin, and a hydraulic support cylinder mounted on the positioning plate, a hydraulic angle cylinder mounted on one side of the positioning plate, a first side pressure plate mounted on the hydraulic angle cylinder, a first lever cylinder and a second lever cylinder mounted on the other side of the positioning plate, a second side pressure plate and a third side pressure plate mounted on the first lever cylinder and the second lever cylinder respectively, a flip-able auxiliary pressure plate mounted on the upper end and one side of the first positioning pin, an auxiliary pressure plate having a pressure head end at one end and an abutting pressure rod at the other end, the pressure rod being connected to the cylinder, and a return spring between the auxiliary pressure plate and the positioning plate.

[0005] This existing thin-walled support anti-deformation hydraulic clamp uses a hydraulic cylinder and positioning pin to position the product, and then uses a cylinder to drive the pressure plate to clamp it.

The fixture is characterized by further including: an elastic positioning device 3 disposed on the base 1 for detecting whether the product is installed in place; the elastic positioning device 3 includes a positioning mounting seat 31 disposed on the base 1, a pin seat 32 disposed on the positioning mounting seat 31, a pin 33 passing through the pin seat 32 for insertion and positioning with the product, and an elastic element disposed within the pin seat 32 for floating support of the pin 33.

[0028] In this invention, the elastic positioning device 3 is inserted into the positioning hole of the product via a pin 33 to ensure that the product is placed in place. When the pin 33 is not inserted into the positioning hole of the product, the upper end face of the pin 33 will contact the end face of the product, thereby causing the pin 33 to be pressed downward and compress the elastic element. At the same time, the product will also move slightly and separate from the clamping mechanism 2, causing the airtightness test to fail, thus determining that the product is not installed in place, effectively reducing the defect rate of processing and greatly improving the processing quality.

[0029] Combination Figure 3 As shown, the elastic element is a support spring 34, which is sleeved on the lower end of the pin 33 and lifts the pin 33. Here, the support spring 34 is sleeved on the lower end of the pin 33, and the upper and lower ends of the support spring 34 abut against the pin 33 and the positioning mounting seat 31 respectively, so as to provide floating support for the pin 33.

The upper end surface of the first inclined mounting base 251 is inclined. Here, both the first inclined top 253 and the first inclined support top 254 of the first inclined clamping cylinder 252 are inclined, having a certain angle, so as to support and position the inclined parts of the product, providing a better positioning effect.

The first pressing head 292 is provided with a first slot 295 for corresponding engagement with the first limiting shaft 294. Here, the first pressing cylinder 291 drives the first pressing head 292 to press down, so that it cooperates with the first support cylinder 293 to perform lateral clamping and positioning of the product.

[0034] The third clamping and positioning device 210 includes a third pressing cylinder 211 mounted on the base 1, a third pressing head 212 connected to the output end of the third pressing cylinder 211 and driven by the third pressing cylinder 211 to press down, a third support cylinder 213 mounted on the base 1 and used to cooperate with the third pressing head 212 to clamp the product, a third limiting shaft 214 mounted on the upper end of the third pressing cylinder 211 and used to circumferentially limit the third pressing head 212, and a fourth clamping device 215 mounted in the third support cylinder 213 and used to clamp the product.

[0037] In summary, in this utility model, the elastic positioning device 3 is inserted into the positioning hole of the product by a pin 33 to ensure that the product is placed in place. When the pin 33 is not inserted into the positioning hole of the product, the upper end face of the pin 33 will contact the end face of the product, thereby causing the pin 33 to be pressed downward and compress the elastic element. At the same time, the product will also move slightly and separate from the clamping mechanism 2, causing the airtightness test to fail, thus judging that the product is not installed in place, effectively reducing the defect rate of processing and greatly improving the processing quality.
