TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, in particular to a high-precision part batch detection clamping device and an assembling method thereof. BACKGROUND

[0002] In the structural part inspection process, when using a three-coordinate measuring machine to collect data of some high-precision structural parts, the structural parts need to be stably clamped, so that the equipment can collect more data, take points more accurately, and has higher efficiency.

[0003] The existing clamping methods mostly use V-shaped iron, oil mud, and vise to clamp, and cannot realize batch stable clamping of parts for batch detection, but only can measure single parts, and the detection efficiency is low. SUMMARY

[0004] One of the purposes of the present application is to provide a high-precision part batch detection clamping device, which has the advantages of convenient and fast clamping, stable structure, and high universality, and is used to solve the clamping problem of batch detection of some high-precision structural parts by using a three-coordinate measuring machine.

[0005] The technical scheme adopted by the present application to solve the technical problem is: a high-precision part batch detection clamping device, comprising a supporting bottom plate and a plurality of clamping mechanisms arranged in an array on the supporting bottom plate, wherein the clamping mechanism is composed of a limiting block, a pressing device, and a fixing seat arranged between the limiting block and the pressing device, the surface of the fixing seat is transversely provided with a through groove with a V-shaped cross section, the pressing device comprises a pressing seat and a mounting hole penetrating through the pressing seat, a top rod with one end large and one end small and an adjusting bolt are respectively arranged on the front and rear sides of the mounting hole, a spring is arranged between the top rod and the adjusting bolt in the mounting hole, and the fixing seat, the pressing seat, and the limiting block are respectively installed on the supporting bottom plate through screws.

[0006] The mounting hole of the high-precision part batch detection clamping device gradually increases in diameter from front to back, and the outer diameter of the front end of the top rod is smaller than that of the rear end, that is, one end is large and one end is small.

[0007] The limiting block and the pressing seat of the high-precision part batch detection clamping device are respectively installed on the front and rear sides of the through groove.

[0008] The limiting block of the high-precision part batch detection clamping device is processed from an aluminum plate, and a dovetail groove is arranged on the side close to the fixing seat.

[0009] The two surfaces of the through groove of the high-precision part batch detection clamping device are at an angle of 120°.

[0010] The high-precision parts batch inspection clamping device has 50 clamping mechanisms, and the fixed seats are distributed on the support base plate with a horizontal spacing of 20mm and a vertical spacing of 70mm.

[0011] The second objective of this invention is to provide an assembly method for a high-precision batch inspection and clamping device for parts, the steps of which are as follows:

[0012] Step 1: Insert the push rod into the mounting hole of the clamping seat starting from the small end until the small end protrudes from the front of the mounting hole, and rotate and push the push rod to ensure that the push rod can rotate smoothly and extend and retract freely on the spring;

[0013] Step 2: Place the spring into the inner cavity of the mounting hole, with one end in contact with the large end of the push rod and place it stably.

[0014] Step 3: Screw the adjusting bolt into the threaded hole on the back side of the mounting hole until it is flush with the right end face of the spring or push rod. Press the part of the push rod that extends out of the mounting hole cavity and check whether the front end of the push rod can freely extend and retract to pop out the clamping seat.

[0015] Step 4: Install the fixing seat and the clamping device side by side on the support base plate;

[0016] Step 5: Repeat steps 1, 2, and 3 above to install 50 clamping devices and fixing seats onto the support base plate. During installation, the mounting surfaces of the fixing seats and clamping devices should be flush with the mounting surfaces of the support base plate. Align the threaded holes and screw in the screws to ensure stability.

[0017] Step 6: Install 50 limit blocks on the front side of the fixed base. During installation, the bottom surface of the limit block should be flush with the mounting surface of the support base plate. Align the threaded holes and screw in the screws to ensure stability.

[0018] The beneficial effects of this invention are: firstly, it can be used for horizontal clamping. When performing inspection, the parts are horizontally clamped on the 50 V-grooves of the support base plate, which can realize batch clamping of parts with a maximum diameter of Φ60mm and a maximum length of 50mm; secondly, it can be used for vertical clamping. When performing inspection, the bottom surface of the parts is close to the upper surface of the base plate and is positioned by 50 sets of limiting block V-grooves, which can realize batch clamping of square or cylindrical parts with a maximum clamping size of 50mm.

[0019] This invention enables quick and convenient clamping of parts for batch inspection, allowing for the batch clamping of parts of different sizes and shapes. Up to 50 parts can be clamped for measurement at a time. The clamping is convenient and the structure is stable. It can effectively solve the current problem of batch inspection of small shafts and irregular parts, and has strong practicality. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, the present invention discloses a high-precision parts batch inspection clamping device, which consists of a support base plate 1, a fixed seat 2, a clamping device 3, a limiting block 4, a top rod 5, a spring 6, an adjusting bolt 7, and a screw 8. The fixed seat 2, the clamping seat of the clamping device 3, and the limiting block 4 are respectively installed on the support base plate 1 by screws 8.

[0025] As described above, the support base plate 1 is the final mounting platform for all mechanisms and also serves as the support platform for clamping parts during batch measurement. Multiple clamping mechanisms are arranged in an array on the support base plate 1, with up to 50 clamping mechanisms. The V-shaped through groove on the surface of the fixing seat 2 serves as the cylindrical generatrix support surface for horizontal clamping, and the upper surface serves as the bottom support surface for vertical clamping. The fixing seat 2 is machined to be 50mm long, 41.5mm wide, and 15mm high, with a V-angle of 120°. The base plate is 600mm long, 600mm wide, and 15mm thick. The support base plate 1 has 50 sets of 4 sets of 4-limiting blocks and 4×Φ6.5 mounting holes for the clamping device 3. Considering the space constraints for batch measurement and the installation of the limiting blocks 4 and clamping device 3, the fixing seats 2 are distributed on the support base plate 1 with a lateral spacing of 20mm and a longitudinal spacing of 70mm. When all mechanisms are assembled, it can be used as a batch inspection clamping platform.

[0026] The clamping device 3 includes a clamping seat and a mounting hole penetrating the clamping seat. A push rod 5 and an adjusting bolt 7 are respectively provided on the front and rear sides of the mounting hole. The inner diameter of the mounting hole gradually decreases from front to back. The outer diameter of the front end of the push rod 5 is smaller than that of the rear end, that is, one end is larger and the other end is smaller. A spring 6 is provided in the mounting hole between the push rod 5 and the adjusting bolt 7. The clamping seat is the mounting platform for the push rod 5, the spring 6, and the adjusting bolt 7. All the mechanisms are installed in it. The adjusting bolt 7 is used to adjust the pressure of the spring 6 when clamping. The push rod 5 is used to fix the workpiece to be measured during clamping and works together with the spring 6 and the adjusting bolt 7 to achieve the clamping and fixing of workpieces of different sizes. The limiting block 4 is installed on the support base plate 1 by screws 8.

[0027] Furthermore, the limiting block 4, machined from aluminum plate, serves as a limiting and supporting device for the clamping mechanism, and is installed on the front and rear sides of the through slot, respectively, along with the clamping seat. The limiting block 4 functions as a supporting surface for the cylindrical bottom during horizontal clamping and a limiting surface for the cylindrical surface during vertical clamping. To accommodate the clamping of some irregularly shaped parts, a dovetail groove is specifically provided near the fixed seat 2 for auxiliary positioning and clamping. The limiting block 4 has a total height of 29mm, a length of 41.5mm, and a width of 20mm. It is fixed to the right side mounting surface of the fixed seat 2 via a threaded hole at the bottom and secured with screws 8. Together with the clamping device 3 and the fixed seat 2, it achieves the horizontal and vertical clamping and fixing of workpieces of different sizes.

[0028] The assembly method of a high-precision structural component batch inspection clamping device as described above includes the following steps.

[0029] Step 1: Insert the push rod 5 into the mounting hole of the clamping seat starting from the small end until the small end protrudes from the front of the mounting hole. Rotate and push the push rod 5 to ensure that the push rod 5 can rotate smoothly and extend and retract freely on the spring 6.

[0030] Step 2: Place the spring 6 into the inner cavity of the mounting hole, with one end in contact with the large end of the push rod 5 and place it stably.

[0031] Step 3: Screw the adjusting bolt 7 into the threaded hole on the back side of the mounting hole until it is flush with the right end face of the spring 6 or the push rod 5. Press the part of the push rod 5 that extends out of the mounting hole cavity and check whether the front end of the push rod 5 can freely extend and retract to pop out the clamping seat.

[0032] Step 4: The fixing seat 2 and the clamping device 3 are installed side by side on the support base plate 1.

[0033] Step 5: Repeat steps 1, 2, and 3 above to install 50 clamping devices 3 and fixing seats 2 onto the support base plate 1. During installation, the mounting surfaces of the fixing seats 2 and clamping devices 3 should be in contact with the mounting surfaces of the support base plate 1. Align the threaded holes and screw in the screws 8 to ensure stability.

[0034] Step six: Install 50 limiting blocks 4 on the front side of the fixed base 2. During installation, the bottom surface of the limiting block 4 should be flush with the mounting surface of the support base plate 1, and the screws 8 should be screwed into the threaded holes to ensure stability.
