For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0056] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0057] like Figure 1-Figure 16As shown, this embodiment provides an automatic clamping device for anodized workpieces with titanium alloy bolt surface treatment, the clamping device includes a clamping assembly 100 and a bolt feeder 200, the clamping assembly 100 and the bolt feeder 200 are connected via a feeding air pipe 300, the bolt feeder 200 conveys the clamping bolts 180 to be processed to the clamping assembly 100 one by one, and the clamping assembly 100 clamps them to the clamping spring 150.

[0058] The clamping assembly 100 includes a clamping spring 150 and a pusher, wherein the clamping spring 150 can rotate and move downward along its spiral direction, and the pusher can push the clamping bolts 180 delivered by the feeding air pipe 300 into the gap of the clamping spring 150 one by one as the clamping spring 150 moves downward. The clamping spring 150 gathers multiple clamping bolts 180 together by the clamping force between adjacent coils of the spring, forming a string-like clamping structure.

[0059] The clamping assembly 100 and the clamping device provided in this embodiment can insert the clamping bolts 180 to be processed into the clamping springs 150 that move downward spirally one by one through the ejector, so that the clamping springs 150 form a string-shaped clamping structure, so as to facilitate the surface treatment of the workpiece. The clamping device realizes the flexible automatic clamping of discrete products, greatly reduces the labor, ensures the stability of clamping, and improves the clamping efficiency.

[0060] In the clamping assembly 100 provided in this embodiment, a roller 190 is provided on the side of the clamping spring 150, and the outer wall of the roller 190 can be made of a material with a certain friction force such as rubber, preferably a flexible damping material, so that the roller 190 can drive the clamping spring 150 to rotate through the friction force of its circumferential side wall. Specifically, the roller 190 can be driven to rotate by a clamping motor 191 or other power equipment.

[0061] At the same time, at least one supporting roller 1120 is provided on the side of the clamping spring 150, and the at least one supporting roller 1120 can rotate along its axis, and at least one annular protrusion 1121 is provided on the supporting roller 1120 along its circumference, and the at least one annular protrusion 1121 can be inserted into the gap of the clamping spring 150 to provide a guide for the spiral downward movement of the clamping spring 150. The number of supporting rollers 1120 and annular protrusions 1121 can be set as needed.

[0062] Illustratively, the clamping assembly 100 provided in this embodiment includes two support rollers 1120, each support roller 1120 is provided with two annular protrusions 1121 at intervals, and the positions of the annular protrusions 1121 of the two support rollers 1120 need to be configured according to the positional relationship between them and the gap between the clamping spring 150.

[0063] Of course, in other embodiments, the structure can also be used to realize the rotation and downward movement of the clamping spring 150, for example, the clamping spring 150 is installed in a cylindrical structure, a push-down member is set on the top of the clamping spring 150 to press the clamping spring 150 downward to make it move downward, and at least one rod-shaped structure is inserted into the gap of the clamping spring 150 to make the clamping spring 150 rotate and move downward in a spiral manner, etc. Of course, the push-down member and the rod-shaped structure can also be combined with the roller 190 and the support roller 1120 to realize the spiral downward movement of the clamping spring 150, which is not limited here.

[0064] The automatic clamping equipment for anodized workpieces with titanium alloy bolt surface treatment provided in this embodiment also includes an assembly component for assembling the support roller 1120. Specifically, the assembly component includes an assembly plate 1131 and two side plates 1132 that are U-shaped and arranged around the outer periphery of the support roller 1120. The assembly plate 1131 is hinged to one of the two side plates 1132 through an articulated structure such as a hinge, and is connected and fixed to the other through a clamping member 1133. The upper and lower sides of the assembly plate 1131 are fixed with a positioning plate 1134 through fasteners such as bolts. The support roller 1120 is arranged between the two positioning plates 1134 and is rotatably connected to the positioning plates 1134. This design allows equipment maintenance personnel to more conveniently check and replace the support roller 1120 to be suitable for clamping springs 150 with different pitches.

[0065] In this embodiment, the clamping member 1133 is an L-shaped clamping block, one end of which is hinged to the side plate 1132, and the other bent end is buckled on the assembly plate 1131. The clamping block is provided with buckling thrust by an elastic structure. Exemplarily, the clamping block can be rotatably connected to the side plate 1132 via a rotating shaft fixed to the side plate 1132, and the clamping block is kept buckled on the assembly plate 1131 by an elastic structure such as a torsion spring.

[0066] Of course, in other embodiments, other types of hinge structures and elastic structures may be used to achieve the above functions of the assembly component. For example, the hinge structure may be used to achieve the hinge connection between the clamping block and the side plate 1132, and an elastic structure such as a spring disposed on the side of the clamping block facing away from the side plate 1132 may be used to push the clamping block toward the side plate 1132, so that the clamping block remains in a buckled state.

[0067] Of course, in other embodiments, other forms of assembly components may be used to define the position of the support roller 1120. For example, the assembly plate 1131 and the two side plates 1132 are assembled and fixed by fasteners such as bolts. When the support roller 1120 is replaced or repaired, the assembly plate 1131 and the support roller 1120 can be removed by removing the bolts.

[0068] As a preferred solution, the titanium alloy bolt surface treatment anodized workpiece automatic clamping device provided in this embodiment also includes a sleeve 151, which is vertically arranged above the roller 190 and is used to contain the clamping spring 150, so that the clamping spring 150 above the roller 190 remains in an upright state. As a preferred solution, a notch is opened on the side of the sleeve 151 to facilitate observation of the position of the clamping spring 150.

[0069] In the clamping assembly 100 provided in this embodiment, the ejector includes a main body 1101, a clamp 110 and an ejector rod 111, wherein:

[0070] The clamp 110 is composed of two single clamps 1103 that can be opened and closed. Both single clamps 1103 are rotatably connected to the side plates 1102 arranged on both sides of the main body 1101 through structures such as rotating shafts. Specifically, one end of the two single clamps 1103 is rotatably connected to the upper and lower parts of the side plates 1102 respectively, that is, located on the upper and lower sides of the main body 1101, and the other end extends to the front end of the main body 1101. The two single clamps 1103 form a receiving cavity 1104 for accommodating the clamping bolts 180 through the grooves arranged on the adjacent side walls. The front end of the receiving cavity is a conical structure, and the front end of the receiving cavity 1104 is provided with an opening that passes through the clamp 110. The feeding air pipe 300 is fixed to the side of the main body 1101 and is connected to the receiving cavity 1104. The clamping bolts 180 are transported into the receiving cavity 1104 one by one through the feeding air pipe 300.

[0071] The push rod 111 is inserted from the main body 1101 and the rear end of the clamp 110 to the front end opening of the clamp 110, passes through the accommodating cavity 1104, and can move back and forth along the main body 1101 and the clamp 110. The push rod 111 can poke the clamping bolt 180 located in the accommodating cavity 1104 out of the front end opening of the accommodating cavity 1104, so that the clamping bolt 180 is squeezed into the gap of the clamping spring 150, and the two single clamps 1103 are pushed open by the clamping bolt 180 when the clamping bolt 180 is poked out.

[0072] The automatic clamping equipment for anodized workpieces with surface treatment of titanium alloy bolts provided in this embodiment also includes a material pushing power assembly 1110, which includes a base plate 1111, a slide rail 11111 arranged on the base plate 1111, and a first slider 1112 and a second slider 1113 arranged on the slide rail 11111; wherein the clamp 110 is arranged on the second slider 1113, and the push rod 111 is arranged on the first slider 1112.

[0073] A first guide rod 1114 is arranged between the first slider 1112 and the second slider 1113. The first guide rod 1114 is fixedly connected to one of the first slider 1112 or the second slider 1113 and is slidably inserted on the other; or, the first guide rod 1114 is slidably inserted between the first slider 1112 and the second slider 1113; a raised stopper (not shown) is arranged at the sliding end of the first guide rod 1114; a first buffer spring 11141 is wound around the outside of the first guide rod 1114 located between the first slider 1112 and the second slider 1113, and the first buffer spring 11141 is in a compressed state.

[0074] During the operation of the device, the first slider 1112 can be in the power device, such as Figure 4 As shown in the figure, the lifting cylinder 1116 moves forward under the push of the telescopic rod 11161 fixed on the base plate 1111, and under the pushing action of the first buffer spring 11141, the second slider 1113 and the clamp 110 are pushed forward; when the second slider 1113 stops moving under the abutment of the stopper 11131 fixed on the base plate 1111, the telescopic rod 11161 of the lifting cylinder 1116 pushes the first slider 1112 to squeeze the first buffer spring 11141 and continue to move forward until the lifting rod 111 pokes the clamping bolt 180 out from the front end of the clamp 110.

[0075] Among them, the block 11131 is as follows Figure 6 As shown, it can be composed of a fixed block 111311 fixed on the bottom plate 1111 and a blocking rod 111312 arranged on the fixed block 111311. The blocking rod 111312 can be fixed to the fixed block 111311; preferably, the blocking rod 111312 can be slidably inserted in the fixed block 111311, and protruding blocking blocks are arranged at both ends of the blocking rod 111312, and a compression spring (not shown) is arranged between the fixed block 111311 and the blocking block at one end of the blocking rod 111312 close to the second sliding block 1113.

[0076] The first slider 1112 can move backward under the pull of the power device, and when the distance between the first slider 1112 and the second slider 1113 reaches the maximum value, that is, when the stopper at the slidable end of the first guide rod 1114 abuts against the first slider 1112 and / or the second slider 1113, the first guide rod 1114 pulls the second slider 1113 backward to the initial position through its fixed end or the stopper. In the initial position state, the accommodating cavity 1104 is empty, waiting for the clamping bolt 180 to be transported into it by the feeding air pipe 300. As a preferred solution, the ejection power assembly 1110 further includes a second guide rod 1115 and a second buffer spring 11151, wherein one end of the second guide rod 1115 is slidably inserted in the first slider 1112, and the other end is connected to the power device, and is pulled forward and backward by the power device; a raised stopper is provided at the slidable end of the second guide rod 1115; the second buffer spring 11151 is provided between the power device and the first slider 1112; and the second buffer spring 11151 is in a compressed state. The second buffer spring 11151 is used for buffering between the power device and the first slider 1112.

[0077] Of course, in other embodiments, the displacement of the clamp 110 and the push rod 111 can also be achieved by other existing methods. For example, the clamp 110 and the push rod 111 can be pushed forward by cylinders respectively, and the time and sequence of pushing the displacement of the two can be set; for example, the clamp 110 and the push rod 111 can be pushed forward by an electric push rod, or the clamp 110 and the push rod 111 can be pushed forward by a worm gear structure push rod driven by a motor, etc.

[0078] As a preferred solution, the automatic clamping equipment for anodized workpieces with titanium alloy bolt surface treatment provided in this embodiment also includes a support block 130, which is arranged on the opposite side of the clamping spring 150 to the ejector, and provides support force for the clamping spring 150 in the clamping operation by abutting; the height of the ejector is configured to be higher than the ejector, avoiding the position when the clamped clamping bolt 180 is rotated to this side; the support block 130 can be close to or away from the clamping spring 150. Furthermore, the side of the support block 130 facing the clamping spring 150 is concave, and the concave surface is adapted to the size of the clamping spring 150, so as to simultaneously play a role of circumferential limit to the clamping spring 150.

[0079] As a preferred solution, the automatic clamping device for anodized workpieces with titanium alloy bolt surface treatment provided in this embodiment also includes an expansion clamp 120, which is arranged upstream of the spiral line of the clamping position of the ejector and is composed of two jaws that can be opened and closed. The expansion clamp 120 can open the spring gap of the clamping spring 150 at the clamping position by opening and closing the two jaws, so that the clamping bolt 180 poked out from the clamp 110 can be more easily inserted into the gap of the clamping spring 150. It is worth noting that the gap of the clamping spring 150 after being opened by the expansion clamp 120 is still smaller than the diameter of the clamping bolt 180, and the front end thickness of the expansion clamp 120 after closing is smaller than the gap of the clamping spring 150.
