In an alignment stage, a top table 4a, which holds a work piece on which a moving load acts, is disposed above a base 1, and a supporting unit 13 each having three degrees of freedom of X, Y, and θ and driving units 14A, 14B, 14C, and 14D, each having a one-axis direction ball screw linear motion mechanism 9 in addition to the same configuration as that of the supporting unit 13, are interposed between the base 1 and the top table 4a to be disposed at locations corresponding to the center and four corner portions of the top table 4a, which are disposed in a zigzag fashion in a load movement direction L. The ball screw linear motion mechanisms 9 of the driving units 14A and 14B of diagonal positions on one side and the ball screw linear motion mechanisms 9 of the driving units 14C and 14D of diagonal positions on the other side are disposed to be at right angles to each other. A moving load which acts on the top table 4a through a work piece while moving in the load movement direction L is continuously received by the respective driving units 14A and 14C, the supporting unit 13, and the respective driving units 14B and 14D, so that deformation of the top table 4a is suppressed.

The invention discloses a clamping device for bolt locking. The clamping device comprises a base, an inner clamping structure and an outer clamping structure. The inner clamping structure is used for clamping the periphery of a bolt and connected with the base. The outer clamping structure is used for clamping the periphery of the bolt. The outer clamping structure and the inner clamping structure are arranged coaxially, and the outer clamping structure is arranged at the periphery of inner clamping structure in a sleeving mode. The bottom of the outer clamping structure is lower than the bottom of the inner clamping structure. According to the clamping device for the bolt locking, the stability of the bolt during the bolt locking can be improved, so that the probability of disorientation of the bolt in the locking process can be reduced well, and the fact that locking movement is completed successfully is ensured.

This application relates to a universal joint fork ear hole grinding device, which relates to a universal joint fork production equipment, which includes a frame, a grinding motor arranged on the frame, a rotating rod arranged on the motor shaft of the grinding motor, The driving pulley arranged on the rotating rod and the driven pulley arranged on the frame, the driving pulley and the driven pulley are connected by a conveyor belt, and the driven pulley is provided with two A reamer for grinding the ear holes of the joint fork, and the frame is provided with a positioning assembly for fixing the universal joint fork. The effect of the present application is that it can reduce the possibility that the concentricity of the ear holes of the two universal joint yokes deviates, and can also improve the grinding efficiency and productivity.

The present application discloses a connection device, an electronic device, and a processing method. The connection device includes: a first connection structure used to rotatably connect the first body and the second body of the electronic device; a second connection structure used to rotatably connect the first body and the second body of the electronic device; The body and the second body are arranged coaxially with the first connection structure; the cover is located between the first connection structure and the second connection structure, and the two ends of the cover are respectively connected to the first connection structure and the second connection structure, And respectively cover at least part of the first connection structure and at least part of the second connection structure. The above-mentioned connection device, since both ends of the cover are connected, can improve the installation stability of the cover and reduce the probability of the cover being skewed, even The deflection of the cover can be avoided, so that the appearance of the electronic equipment is no longer affected, and the assembly yield of the connecting device is also improved.

The invention belongs to the technical field of sheet metal parts, in particular to a sheet metal part for sheltering rain; it includes an upper sheet metal part and a lower Reinforcing rods, the end of the lower sheet metal part is provided with a plurality of retaining grooves matching the reinforcing rods, and the reinforcing rods obliquely pass through the retaining grooves; the bottom ends of the plurality of reinforcing rods are welded with the same steel wire rope, and the steel wire ropes The two ends are respectively welded on the front side and the rear side of the upper sheet metal part; by setting the reinforcement rod and the steel wire rope in the present invention, the reinforcement rod can pass between the upper sheet metal part and the lower sheet metal part, regardless of whether the upper sheet metal part Whether the part is deformed first or the lower sheet metal part is deformed first, both can play a close role in the two. At the same time, when the reinforcing rod moves, it can drive the two ends of the steel wire rope to tighten the upper sheet metal part, further improving the Fit tightness of the upper sheet metal part and the lower sheet metal part.

The invention relates to the technical field of cutting equipment accessory devices, in particular to cutting equipment for building decoration engineering, which can limit the cutting track of a plate. Thus, the probability that the cutting track of a cutting saw on the plate is inclined is reduced, and the cutting quality of the plate can be improved. The cutting equipment for building decoration engineering comprises a power mechanism and a cutting saw, wherein the cutting saw is installed at the output end of the power mechanism, the power mechanism is provided with a handheld assembly, and the handheld assembly is provided with a switch assembly. The cutting equipment for building decoration engineering further comprises a limiting plate, a fixing plate, a clamping plate, a fasteningthreaded rod, a fastening rotary knob, a sliding block, a driving block, a control plate, a left positioning block, a right positioning block, a fixing ring, a synchronous block and a pin block. The front end of the fixing plate is connected with the bottom area of the rear end of the limiting plate, a fastening sliding hole penetrates through the left area of the front end of the limiting plate,a fastening threaded groove is formed in the left side of the middle of the front end of the clamping plate, and a left positioning sliding groove and a right positioning sliding groove are formed inthe right side and the right end of the top end of the limiting plate respectively.

The invention belongs to the technical field of detection equipment, in particular to a module power-on detection device based on an electric energy meter of the Internet of Things, comprising a base, a thimble, a lifting device and a limit device; the jack on the surface of the module to be detected corresponds to the ejector For matching settings, the position of the thimble is fixed. During the manual insertion and removal of the module to be tested and the thimble in contact, it is very easy to cause the thimble and the jack on the surface of the module to be tested to be misaligned. It is easy to skew, which seriously affects the detection efficiency. By setting a limit device on the top of the lifting device, and using the limit device to place the module to be tested inside the limit device and fix it, the contact between the thimble and the socket on the surface of the module to be tested can be effectively improved. The accuracy rate can avoid the occurrence of dislocation of the ejector pin during the insertion and extraction process, and at the same time, it can effectively reduce the probability of the ejector pin being skewed during the insertion and extraction process, thereby effectively improving the detection efficiency.
