[0028] Referring to Figures 1 to 5 , the following embodiments are made for the dart fixture workstation of the present utility model:

[0029] A dart fixture workstation includes: a turntable device 100 and a self-clamping fixture 200.

[0030] The turntable device 100 has a rotatable turntable 110. The number of the self-clamping fixtures 200 is multiple. The multiple self-clamping fixtures 200 are circumferentially and evenly distributed on the upper side of the turntable 110 around the turntable 110. The self-clamping fixture 200 includes: clamping jaws 210 and an opening mechanism 220. The clamping jaws 210 are arranged in pairs facing each other, and the two clamping jaws 210 arranged in pairs are elastically abutted against each other facing each other. The opening mechanism 220 is used to drive the two clamping jaws 210 to move away from each other.

[0031] During actual use, the turntable 110 of the turntable device 100 rotates, so that the multiple self-clamping fixtures 200 thereon can move synchronously in a cycle. The self-clamping fixture 200 clamps and fixes the dart rod through the clamping jaws 210 that are clamped facing each other, so that the dart rod can move along with the self-clamping fixture 200 along the cyclic path to realize assembly processing. The opening mechanism 220 can drive the two clamping jaws 210 arranged in pairs to open, facilitating the loading and unloading of the dart rod.

[0032] The turntable 110 is in a disc shape. The turntable device 100 includes a rotation driving member 120, and the rotation driving member 120 is in transmission connection with the turntable 110 and rotates the turntable 110 around its own rotation axis.

[0033] In this embodiment, the rotation driving member 120 includes: a rotation driving unit 121 and a speed reducer 122. The speed reducer 122 has a rotation driving end connected to the turntable 110. The rotation driving unit 121 is in driving connection with the speed reducer 122. Considering the convenience of controlling the rotation speed and start-stop accuracy of the turntable 110, the rotation driving unit 121 in this embodiment adopts a servo motor. In some other embodiments, the rotation driving unit 121 can be a rotation driving element such as a stepping motor or a pneumatic motor.

[0034] In a further embodiment, the rotation driving end is in a ring shape, and the rotation driving end is coaxially and fixedly connected to the turntable 110. A fixed shaft 123 is coaxially and rotatably penetrated through the rotation driving end. A fixed disk 130 fixedly connected to the upper end of the fixed shaft 123 is arranged on the upper side of the turntable 110.

[0035] When the rotation driving end drives the turntable 110 to rotate, the fixed shaft 123 and the fixed disk 130 can remain stationary. The fixed disk 130 provides an installation and support basis for the assembly processing mechanism, so that the central space surrounded by the cyclic movement paths of the multiple self-clamping fixtures 200 can be utilized.

[0036] Further, both the fixed disk 130 and the fixed shaft 123 are coaxially provided with a pipeline channel 140 that penetrates up and down. Specifically, the fixed shaft 123 is in a cylindrical shape, the outer side of the fixed shaft 123 is rotationally connected to the rotary drive unit 121, and the pipeline channel 140 is arranged inside the fixed shaft 123. During actual use, the pipeline channel 140 can facilitate wire routing, enabling the assembly mechanism provided on the fixed disk 130 to be conveniently wired and preventing the rotation of the rotating disk 110 and the self-clamping fixture 200 from being affected.

[0037] The self-clamping fixture 200 includes: a fixture base 230. The fixture base 230 has guide posts 231. Both of the two jaws 210 are slidably connected to the guide posts 231. The two jaws 210 have clamping grooves 211 arranged facing each other.

[0038] In this embodiment, the guide posts 231 extend in the horizontal direction and are perpendicular to the radial direction of the rotating disk 110. The guide posts 231 are in a cylindrical shape. Preferably, the number of the guide posts 231 is more than two, and multiple guide posts 231 can prevent the jaws 210 from flipping while sliding.

[0039] One end of the jaw 210 facing the rotation axis of the rotating disk 110 is slidably sleeved on the guide post 231, and the clamping groove 211 is arranged at the other end of the jaw 210. By the two clamping grooves 211 arranged in pairs tightly abutting against both sides of the dart shaft, the clamping and positioning of the dart shaft are realized.

[0040] To clamp the dart shaft, the cross-section of the clamping groove 211 is in a semi-circular arc shape and axially extends in the up and down direction. Further, the fixture base 230 has a positioning groove 232, and the positioning groove 232 is arranged below the clamping groove 211. Specifically, a positioning block is provided at the outer end of the fixture base 230. The positioning groove 232 is arranged at the upper end of the positioning block. During actual use, through the clamping grooves 211 of the two jaws 210 clamping and positioning each other, the end of the dart shaft can be embedded in the positioning groove 232. The positioning groove 232 provides support and limits the end of the dart shaft, preventing the dart shaft from deflecting or axially moving during the assembly and processing. In addition, during the feeding of the dart shaft to the self-clamping fixture 200, the positioning groove 232 can position the end of the dart shaft, facilitating the unified clamping position of the jaws 210.

[0041] The opening mechanism 220 includes a jacking member 221. The jacking member 221 is slidably connected to the fixture base 230. The sliding direction of the jacking member 221 is perpendicular to the axial direction of the guide post 231. In this embodiment, the jacking member 221 is slidably arranged along the radial direction of the rotating disk 110.

[0042] The ejecting member 221 has an ejecting slot 222 disposed obliquely, and the clamping jaw 210 is in driving connection with the ejecting slot 222. The extending direction of the ejecting slot 222 is inclined at an angle of 45 degrees to both the sliding direction of the ejecting member 221 and the sliding direction of the clamping jaw 210. The clamping jaw 210 has a driving end slidably embedded in the ejecting slot 222. When the ejecting member 221 slides relative to the jig base 230, the clamping jaw 210 can be driven to slide relative to the jig base 230 through the ejecting slot 222.

[0043] To synchronously drive the sliding of two pairs of the clamping jaws 210, the ejecting slots 222 are arranged in pairs, and the paired ejecting slots 222 extend in mutually perpendicular directions, so that the two clamping jaws 210 slide in opposite directions along the guide post 231, realizing the clamping of the two clamping jaws 210 approaching each other or the loosening of the two clamping jaws 210 moving away from each other.

[0044] To enable the two clamping jaws 210 to elastically abut against each other, the ejecting member 221 or the clamping jaw 210 is elastically connected to the jig base 230, so that the two clamping jaws 210 can elastically abut against each other.

[0045] In this embodiment, the ejecting member 221 is elastically connected to the jig base 230. One end of the ejecting member 221 is sleeved with a spring. The two ends of the spring are elastically abutted against the ejecting member 221 and the jig base 230 respectively, so that the ejecting member 221 has a tendency to slide relative to the jig base 230 under the action of the elastic force, thereby enabling the two clamping jaws 210 to elastically clamp each other. When the ejecting member 221 is driven by an external force to overcome the elastic force and move, the two clamping jaws 210 move away from each other and open under the drive of the ejecting slot 222.

[0046] In some other embodiments, the clamping jaw 210 is elastically connected to the jig base 230. A spring is sleeved outside the guide post 231, and the two ends of the spring are elastically abutted against the clamping jaw 210 and the jig base 230 respectively.

[0047] Further, to avoid manually operating to push the ejecting member 221 and realize the automation of the opening and closing of the clamping jaw 210, the opening mechanism 220 further includes an opening driving unit 223. The opening driving unit 223 has a telescopic opening driving end for driving the ejecting member 221 to move relative to the jig base 230. In this embodiment, the opening driving unit 223 is a cylinder. The opening driving unit 223 is fixedly installed on the upper side of the fixed disk 130. The opening driving unit 223 is arranged along the radial direction of the rotating disk 110. In some other embodiments, the opening driving unit 223 can also adopt linear driving members such as an electric push rod, a hydraulic push rod or a screw nut driving assembly.

[0048] Referring to the accompanying drawings, in this embodiment, the self-clamping fixture 200 is arranged in pairs in a double-station form. The two self-clamping fixtures 200 arranged in pairs are arranged side by side flush with each other.

[0049] When assembling and processing darts using the dart fixture workstation of the present utility model: The rotary drive unit 121 drives the rotating disk 110 to rotate through the speed reducer 122, so that a plurality of the self-clamping fixtures 200 thereon can rotate synchronously and reach different processing stations in sequence for assembly and processing. Among them, two of the processing stations are respectively a loading station and an unloading station. The two opening drive units 223 are respectively arranged towards the loading station and the unloading station. When the self-clamping fixture 200 rotates to the loading station, the opening drive unit 223 extends to push the ejecting member 221 to move, so that the two jaws 210 move away from each other to achieve opening. At this time, the dart shaft is placed between the clamping grooves 211 of the two jaws 210, and the end of the shaft is embedded in the positioning groove 232. Then, the opening drive unit 223 retracts and resets, the ejecting member 221 resets under the action of the spring, and the two jaws 210 elastically abut against each other, clamping the dart shaft between the two clamping grooves 211. The rotary drive member 120 adjusts the rotation of the rotating disk 110, so that each of the self-clamping fixtures 200 can rotate to each processing station in sequence after loading until reaching the unloading station, and then the two jaws 210 are driven to open by the opening mechanism 220, and the processed shaft is unloaded.
