[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-Figure 6 As shown, a plate chain unit includes a clamp assembly for clamping a workpiece conveyed on the plate chain unit, wherein the clamp assembly includes a locking seat 10 having a length direction and a clamp body 20 relatively sliding along the length direction of the locking seat 10;

[0031] A guide surface 101 is obliquely arranged at the lower part of the first end of the length direction of the locking seat 10, and the guide surface 101 is gradually inclined downward along the direction from the first end to the second end of the length direction of the locking seat 10; the first end of the length direction of the locking seat 10 and the second end of the length direction of the locking seat 10 are used to distinguish the two ends of the length of the locking seat 10. When the clamp assembly is used, it is generally used in pairs, and the guide surface 101 is arranged at the far end of a pair of clamp assemblies arranged opposite to each other;

[0032] The clamp body 20 includes a clamp main shell 201, a clamping middle rod 202 vertically arranged in the clamp main shell 201, and an elastic reset member 203; the clamping middle rod 202 can move up and down in the clamp main shell 201, the upper end of the clamping middle rod 202 extends upward from the clamp main shell 201, and a clamping piece 204 is arranged on the clamping middle rod 202 that extends upward, and a walking component 205 extending out of the clamp main shell 201 is arranged at the lower part of the clamping middle rod 202, and the side of the walking component 205 is against the guide surface 101, and the elastic reset member 203 is arranged in the clamp body 20 and is in a force storage state, giving the clamping middle rod 202 a tendency to move upward relative to the clamp main shell 201; the walking component 205 can be a round rod pile, a long strip, a block, a roller, etc., as long as it can contact with the guide surface 101 and slide on the guide surface 101;

[0033] When the clamp body 20 is moved from the first end to the second end along the length direction of the locking seat 10 by the first external force, the clamp main shell 201 is translated relative to the locking seat 10, and the walking part 205 is moved downward along the guide surface 101. At the same time, since the length of the clamping middle rod 202 is fixed, the clamping middle rod 202 can only overcome the resistance of the reset spring member and move downward relative to the locking seat 10 under the action of the first external force, driving the clamping piece 204 to be pressed downward; due to the special design of the clamp body 20 of the guide surface 101, when the clamp body 20 is subjected to the horizontal first external force from the first end to the second end along the length direction of the locking seat 10, the clamping piece 204 can be pressed downward when the translation clamp body 20 is translated as a whole; in actual use, the two clamp assemblies are relatively arranged on the two opposite sides of the workpiece, and the above-mentioned first external force is applied at the same time, so as to realize the clamping of the two opposite clamps and the upper and lower parts of the workpiece, and realize the effective fixation of the position of the workpiece.

[0034] Further, such as Figure 1-Figure 2 , Figure 5-Figure 6 As shown, one end of the guide surface 101 facing the first end in the length direction of the locking seat 10 is connected to an upper buffer surface 102, and one end of the guide surface 101 facing the second end in the length direction of the locking seat 10 is connected to a lower buffer surface 103, and the upper buffer surface 102 and the lower buffer surface 103 are arranged horizontally;

[0035] Specifically, when the walking component 205 is on the upper buffer surface 102, the clamping piece 204 is at the highest point. When the clamping body 20 is subjected to a first horizontal external force from the first end to the second end along the length direction of the locking seat 10, the walking component 205 reaches the lower buffer surface 103 from the upper buffer surface 102 via the guide surface 101. When the walking component 205 is on the lower buffer surface 103, the clamping piece 204 is at the lowest position, that is, the position where the workpiece is clamped; that is, the height difference between the upper and lower ends of the guide surface 101 is the travel distance of the clamping piece 204 downward movement. By limiting the height of the lower end of the guide surface 101, that is, the lower buffer surface 103, different degrees of clamping of the workpiece can be achieved. Of course, it is also possible that the position of the guide surface 101 does not match the expected clamping position of the workpiece, resulting in the workpiece being clamped when the walking component 205 is still on the guide surface 101.

[0036] Further, such as Figure 1 , Figure 6 As shown, a horizontal push component 206 is provided on the lower side of the clamp main shell 201, and the lower end of the horizontal push component 206 exceeds the lower edge of the walking component 205 and the locking seat 10. The first external force can directly act on the horizontal push component 206 to realize the horizontal movement of the clamp body 20 (the locking seat 10 does not move at this time), and will not interfere with the movement of the locking seat 10 and the clamp body 20;

[0037] Specifically, in actual use, the first external force pushes the clamp bodies 20 on a row of plate chain units as a whole through the horizontally movable positioning and adjustment frame, and the horizontal push component 206 can be a horizontal push cylinder or a roller, and while being pushed by the positioning and adjustment frame, it can also move along the positioning and adjustment frame with the transmission of the plate chain unit;

[0038] Preferably, the walking component 205 includes a first roller with a horizontal axis, and the first roller rolls along the guide surface 101; the pushing component 206 includes a second roller with a vertical axis. By arranging the rollers, the resistance and wear of the locking seat 10 and the clamp body 20 to the positioning and adjustment frame when the plate chain unit rotates are reduced.

[0039] Further, such as Figure 1 , Figure 5 , Figure 6 As shown, the locking seat 10 is provided with a whole pushing component 105 close to the second end of the length direction of the locking seat 10, and the lower end of the whole pushing component 105 exceeds the lower edge of the second end of the length direction of the locking seat 10, and the clamp main shell 201 is provided with a pulling hole 209 facing the second end of the length of the locking seat 10, and a tensioning member 104 is hooked on the pulling hole 209, and the other end of the tensioning member 104 is connected to the second end of the length of the locking seat 10; the tensioning member 104 connects the locking seat 10 and the clamp main shell 201, and the tensioning member 104 is an elastic member such as a tensioning spring, a tensioning rubber band or an angle spring, which gives the clamp body 20 a tendency to move from the first end of the locking seat 10 to its second end;

[0040] Specifically, the clamping member is a tension spring. In actual use, generally two relative clamp assemblies are moved simultaneously. The second external force acts on the whole pushing member 105 to realize the movement of the locking seat 10. At the same time, because the tension spring has a minimum length when not subject to external force, it can simultaneously drive the horizontal movement of the clamp body 20, thereby realizing the adjustment of the minimum spacing between the two clamp bodies 20; at this time, the first external force is continuously applied to the horizontal pushing member 206 to make the tension spring longer. The degree of the first external force is different, and the length of the tension spring changes differently, so that the specific relative fine adjustment between the two relatively arranged clamping pieces 204 can be carried out according to the length change of the tension spring (this relative fine adjustment is relative to the moving range of the locking seat 10), thereby realizing the clamping and release of the workpiece;

[0041] In actual use, under the condition of using two relatively two clamping components, a groove is set on the circumference of the positioning and adjusting frame, and the whole pushing component 105 is a slider or a roller sliding in the groove. At this time, the distance between the two locking seats 10 is relatively fixed; a flange is set on the side of the aforementioned positioning and adjusting frame, and the thickness of the flange is thicker at both ends and the lower side of the length of the positioning and adjusting frame. The flat pushing component 206 slides along the flange to realize the position of the clamp body 20 and the change of the length of the tensioning member 104; when the flat pushing component 206 slides on the upper side of the flange, the position between the two clamping bodies 20 is the shortest, and the clamping bodies 20 are pulled closer to each other by the tensioning member 104, and the walking component 205 moves downward along the guide surface 101 at the same time, between the two clamping sheets 204 and the clamping The middle rods 202 are close to each other to clamp the workpiece, while the clamping plates 204 press down to clamp the workpiece; when the push component 206 moves to the two ends of the flange, due to the increase in the thickness of the flange, the clamp body 20 is pushed outward by the thicker edge of the flange, that is, it slides upward along the guide surface 101, and the distance between the two clamping middle rods 202 increases, loosening the two sides of the workpiece, and at the same time the clamping plate 204 moves up to loosen the upper surface of the workpiece, thereby releasing the workpiece, that is, the clamp assembly of the present invention cooperates with the specially designed positioning and adjustment frame to realize automatic clamping and release of the workpiece; it should be noted that, in order to cooperate with the change in flange thickness, the clamping shaft 2021 can be rotated in the clamp main shell 201 to ensure that the push component 206 is in good contact and fit with the flange.

[0042] Further, such as Figure 1-Figure 6 As shown, the clamping middle rod 202 includes a clamping pull plate 208 arranged outside the clamp main shell 201 and a clamping shaft 2021 vertically arranged on the upper surface of the clamping pull plate 208, and the clamping shaft 2021 is provided with a reset connector 207 located in the clamp main shell 201, and the clamping sheet 204 is arranged on the portion of the clamping shaft 2021 extending out of the clamp main shell 201, and the elastic reset member 203 is arranged between the reset connector 207 and the inner wall of the clamp main shell 201, and the reset connector 207 can be a compression spring or a tension spring. When it is a compression spring, such as Figure 4The upper part of the clamp main shell 201 is shown as being provided with an installation cavity, and the clamping middle rod 202 is arranged in the installation cavity, including an axial screw 2022 installed on the clamping pull plate 208, and a clamping shaft rod 2021 threadedly connected to the axial screw 2022, and the upper part of the clamping shaft rod 2021 is provided with a retaining spring protrusion, and a reset connecting member 207 using a compression spring is arranged between the retaining spring protrusion and the bottom wall of the installation cavity; similarly, when the reset connecting member 207 is a tension spring, the retaining spring protrusion is changed to a retaining spring hole, and the position of the retaining spring hole is set to the lower part of the clamping shaft rod 2021, and the tension spring is connected between the upper end of the installation cavity and the retaining spring hole; the walking component 205 is arranged on the clamping pull plate 208; the clamping piece 204 can be round, square or irregular in shape, and is specifically adjusted according to the matching conditions of the actual workpiece.

[0043] Further, such as Figure 1 , Figure 5-Figure 6 As shown, the clamp assembly further includes a clamp guide body 11, the clamp guide body 11 extends in the length direction of the locking seat 10, the clamp guide body 11 is provided with a first horizontal slideway 111 and a second horizontal slideway 112, the locking seat 10 is horizontally provided with a first slide bar 113 that is slidably matched with the first slideway 111, and the clamp main shell 201 is horizontally provided with a second slide bar 114 that is slidably matched with the second slideway 112, the clamp body 20 and the locking seat 10 can be arranged on the same side or the opposite side of the clamp guide body 11, as long as the specific position does not affect the walking component 205 walking on the guide surface 101 and the action of the tensioning member 104;

[0044] Specifically, the clamp guide body 11 includes a guide body with a length direction and a conductor hole 115 arranged in the length direction of the clamp guide, and guide body mounting holes are arranged at both ends of the guide body; the conductor hole 115 is through-through from top to bottom, the first slide 111 is arranged on the opposite sides of the outer periphery of the guide body, and the second slide 112 is arranged on the opposite sides of the inner wall of the conductor hole 115, and accordingly, the number of the first slide bar 113 and the second slide bar 114 are both two, and they are respectively located on the long sides of the locking seat 10 and the clamp main shell 201, the clamp body 20 is slidably connected in the conductor hole 115, and the locking seat 10 is slidably connected outside the guide body; due to the use of two first slides 111 and the second slides 112 arranged relatively to each other, a stable connection of the long sides of the locking seat 10 and the clamp body 20 is achieved, so that the locking seat 10 and the clamp body 20 are more stable when moved by external force.

[0045] Further, such as Figure 1As shown, the plate chain unit further includes a chain plate body 12, a long hole 121 is opened on the chain plate body 12, the clamp guide body 11 is correspondingly installed at the lower side of the long hole 121, the clamp main shell 201 moves in the long hole 121, the clamping middle rod 202 extends upward along the long hole 121, and the clamping piece 204 is arranged above the long hole 121;

[0046] Specifically, the entire clamp assembly is installed on the lower side of the chain plate body 12 through the guide body installation hole of the clamp guide body 11, thereby realizing the overall installation of the clamp assembly, which is convenient and quick.

[0047] The present invention also provides a transmission plate chain, comprising a plate chain unit as described in any one of the above;

[0048] Specifically, after the workpiece is placed from one end of the transmission plate chain, the workpiece can be automatically clamped and automatically released at the other end of the transmission plate chain through the cooperation of the clamp assembly and the positioning adjustment frame. The workpiece in transmission can be reliably fixed on the transmission plate chain, and will not be displaced when the transmission plate chain is paused or other equipment is processing the workpiece, thereby ensuring the processing accuracy, enabling high-quality transmission and processing of the workpiece, and indirectly improving production efficiency.
