DETAILED DESCRIPTION

[0028] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0029] like Figure 2-Figure 4 As shown, the embodiment of the utility model provides a comb tooth clamping mechanism, including two groups of clamping components 100 and a rotating mechanism 200 arranged opposite to each other on the left and right.

[0030] Each clamping assembly 100 includes a rotating support member 110 , a rotating member 120 , a clamping member 130 and a fine-tuning mechanism 140 .

[0031] The rotating member 120 is rotatably mounted on the rotating support member 110 . The rotating axes of the rotating members 120 of the two sets of clamping members 130 are coaxial. A fine-tuning slide rail 121 is disposed on the rotating member 120 . The axis of the fine-tuning slide rail 121 is perpendicular to the rotating axis of the rotating member 120 .

[0032] The clamping member 130 is slidably mounted on the fine-tuning rail 121 , and the comb blank 300 is positioned between the clamping members 130 of the two sets of clamping assemblies 100 . The center plane of the comb blank 300 in the thickness direction is parallel to the fine-tuning rail 121 and is located on the rotation axis of the rotating member 120 .

[0033] In this embodiment, a positioning seat 131 is provided on the clamping piece 130 of one group of clamping assemblies 100, and a positioning groove 1311 is provided at the side end of the positioning seat 131, and a first ejector pin 1312 is provided in the positioning groove 1311; a connecting seat 132 is provided on the clamping piece 130 of another group of clamping assemblies 100, and a second ejector pin 1321 is provided at the side end of the connecting seat 132; a first connecting block 310 and a second connecting block 320 are provided at both ends of the comb blank 300, respectively, the first connecting block 310 is positioned in the positioning groove 1311, a first positioning hole is provided on the first connecting block 310 for positioning with the first ejector pin 1312, and a second positioning hole is provided on the second connecting block 320 for positioning with the second ejector pin 1321.

[0034] In this embodiment, the comb blank 300 can be processed into Figure 4As shown in the shape, when the comb blank 300 is clamped and positioned, the first push pin 1312 and the second push pin 1321 are respectively pushed into the first positioning hole and the second positioning hole at both ends of the comb blank 300, so that it is convenient to clamp and position the comb blank 300, ensuring that the comb blank 300 is accurately installed between the clamping members 130. At the same time, the first connecting block 310 on the comb blank 300 is inserted into the positioning groove 1311 on the positioning seat 131, which can ensure that the comb blank 300 is clamped between the clamping members 130 and will not rotate. After the teeth of the comb blank 300 are opened, the first connecting block 310 and the second connecting block 320 at both ends can be cut off.

[0035] Preferably, a first mounting hole 1313 is provided in the positioning seat 131, one end of the first mounting hole 1313 extends into the positioning groove 1311, a first ejector pin 1312 is adapted to the first mounting hole 1313, and a spring 1314 is provided between the inner end of the first ejector pin 1312 and the inner end of the first mounting hole 1313. When the comb blank 300 is installed, in the initial state, the tip of the first ejector pin 1312 is pushed out of the positioning groove 1311 by the spring 1314, so that it is easy to align the first positioning hole at one end of the comb blank 300 with the tip of the first ejector pin 1312. When the first connecting block 310 at one end of the comb blank 300 is inserted into the positioning groove 1311, the first ejector pin 1312 will be pushed into the first mounting hole 1313, so that the first connection will not be hindered from being inserted into the positioning groove 1311.

[0036] In addition, a second mounting hole 1322 is provided at the end of the connecting seat 132, and the second ejector pin 1321 is adapted in the second mounting hole 1322. The side of the connecting seat 132 is provided with a through groove extending along the second mounting hole 1322 and connected to the side of the connecting seat 132. The side of the second ejector pin 1321 is connected to a push rod 1323 passing through the through groove, and a locking screw 1324 capable of tightening the second ejector pin 1321 is threadedly connected to the connecting seat 132. When installing the comb blank 300, first place the tip of the first thimble 1312 against the first positioning hole at one end of the comb blank 300, and then move the second thimble 1321 through the push rod 1323 so that the tip of the second thimble 1321 is against the second positioning hole at the other end of the comb blank 300. After the second thimble 1321 presses the comb blank 300, tighten the locking screw 1324 to lock the second thimble 1321 in the connecting seat 132, so that the comb blank 300 can be fixedly installed. After the teeth of the comb blank 300 are opened, loosen the locking screw 1324, and retract the second thimble 1321, and the comb can be removed.

[0037] The fine-tuning mechanism 140 is used to drive the clamping member 130 to slide along the fine-tuning slide rail 121. In this embodiment, the fine-tuning mechanism 140 includes a micro-motor 141, a gear 142 and a rack 143. The micro-motor 141 is installed on the rotating member 120, and the gear 142 is coaxially installed on the output shaft of the micro-motor 141. The rack 143 is fixed on the clamping member 130, and the gear 142 and the rack 143 are meshed. In this way, controlling the micro-motor 141 to drive the gear 142 to rotate can drive the clamping member 130 to slide along the fine-tuning slide rail 121.

[0038] The rotating mechanism 200 is used to drive the rotating members 120 of the two groups of clamping assemblies 100 to rotate synchronously. In this embodiment, the rotating mechanism 200 includes a rotating motor 210, which is installed on the rotating support member 110 of a clamping assembly 100 and is used to drive the rotating member 120 of the clamping assembly 100 to rotate. The front parts of the rotating members 120 of the two groups of clamping assemblies 100 are connected by a connecting rod 220, so that when the rotating motor 210 drives the rotating member 120 of one group of clamping assemblies 100 to rotate, the rotating member 120 of the other group of clamping assemblies 100 will be driven to rotate through the connecting rod 220, thereby ensuring that the rotating members 120 of the two groups of clamping assemblies 100 rotate synchronously.

[0039] In order to realize the rotation connection between the rotating member 120 and the rotating support member 110, a connecting sleeve 122 is provided on one side of the rotating member 120, and the connecting sleeve 122 is installed on the rotating support member 110 through a bearing 121. In order to realize the driving of the rotating member 120 by the rotating motor 210, the output shaft of the rotating motor 210 is drivingly connected with the connecting sleeve 122 of a corresponding group of clamping assemblies 100.

[0040] For comb teeth whose arc tooth roots are not in a straight line, since the center of each arc tooth root is different, when the comb blank 300 is fixed between the clamping members 130 of the two groups of clamping assemblies 100, it is impossible to make the center of the arc tooth root of each comb tooth on the rotation axis. The present application can drive the comb blank 300 clamped between the two clamping members 130 to slide relative to the rotating members 120 on both sides through the fine-tuning mechanism 140, so that when each comb tooth is opened, the center of the corresponding arc tooth root can be adjusted to the rotation axis. In this way, when the comb blank 300 is driven to rotate by the rotating mechanism 200, the cutting disk can cut the comb teeth with arc tooth roots on the comb blank 300. Therefore, the present application facilitates the adjustment of the position of the clamped comb blank 300 to meet the requirements of comb tooth cutting processing whose arc tooth roots are not in a straight line.
