[0001] The utility model relates to the technical field of clamps, in particular to an adaptive clamp for an ultrasonic welding head. Background Art
[0002] When an ultrasonic welding machine is processing a workpiece, the workpiece needs to be fixed. Conventional fixtures cannot be adapted to the fixation of workpieces of different specifications, thus affecting the stability of the workpiece fixation.
[0003] The existing patent CN216466246U is an ultrasonic welding machine for plastic processing. By pulling the fixing plates outward, the distance between the fixing plates is increased, and the connection between the mounting plates and the ultrasonic welding machine body is disconnected, so that the clamp can be removed conveniently. The distance between the two sets of fixing plates can be adaptively adjusted to meet different installation requirements. The elastic member telescopic spring allows the support plate to move up and down, so that the workpiece can be in close contact with the welding area of the ultrasonic welding machine body, thereby ensuring the quality of welding and increasing the use effect of the clamp.
[0004] However, in the process of using an ultrasonic welding machine for plastic processing according to an existing patent, since the two sets of fixed plates are connected only by connecting springs, although adaptive adjustment between the fixed plates can be achieved, the connection between the fixed plates and the ultrasonic welding machine body is prone to loosening, thereby affecting the welding accuracy of the workpiece. Utility Model Content

[0006] To achieve the above-mentioned objectives, the utility model provides an adaptive clamp for an ultrasonic welding head, comprising a base and a clamping device, wherein through grooves are provided on both sides of the base, the through grooves pass through the base, the clamping device is installed on the base, and also comprises a base fixing device, the base fixing device comprises a first fixing plate, a second fixing plate, a connecting spring, a first fixing rod, a second fixing rod and a locking assembly, the first fixing plate and the second fixing plate are respectively slidably installed on both sides of the base and respectively pass through the through grooves, the two ends of the connecting spring are respectively fixedly connected to the first fixing plate and the second fixing plate, the first fixing rod is fixedly installed on the first fixing plate, the second fixing rod is fixedly installed on the second fixing plate, and the locking assembly enables the first fixing rod and the second fixing rod to be locked with each other.
[0007] Wherein, the locking assembly includes a locking screw and a locking cylinder, the locking screw is fixedly mounted on the first fixing rod and is located at one end of the first fixing rod close to the second fixing rod; the locking cylinder is slidably mounted on the second fixing rod, and the second fixing rod passes through the locking cylinder.
[0008] Wherein, the base fixing device also includes a first anti-skid plate and a second anti-skid plate, the first anti-skid plate is fixedly mounted on the first fixing plate; the second anti-skid plate is fixedly mounted on the second fixing plate.
[0009] Wherein, the clamping device comprises an electric push rod and a clamping block, the electric push rod is fixedly mounted on the base; the clamping block is fixedly mounted on the output end of the electric push rod.
[0010] Wherein, the clamping device further comprises a third anti-slip plate, and the third anti-slip plate is fixedly mounted on the clamping block.
[0011] The utility model discloses an ultrasonic welding head adaptive clamp. When in use, the first fixing plate and the second fixing plate are pulled to both sides respectively. At this time, the connecting spring is subjected to the tensile force and is in a stretched state. Then, the first fixing plate and the second fixing plate are respectively in contact with both sides of the ultrasonic welding body. Then, the connecting spring drives the first fixing plate and the second fixing plate to be in close contact with both sides of the ultrasonic welding body under the action of its own elastic force. Then, the locking cylinder is driven to move along the second fixing rod toward the direction of the locking screw on the first fixing rod. When the locking cylinder approaches the locking screw, the locking cylinder is rotated so that the locking screw and the locking cylinder are thread-locked, so that the first fixing plate and the second fixing plate are pressed against the ultrasonic welding body, thereby avoiding looseness in the connection between the first fixing plate and the second fixing plate and the ultrasonic welding body, thereby ensuring the welding accuracy of the workpiece.

The first fixing rod 106 is fixedly mounted on the first fixing plate 103, and the second fixing rod 107 is fixedly mounted on the second fixing plate 104. The locking assembly enables the first fixing rod 106 and the second fixing rod 107 to be locked with each other. The cross-sections of the first fixing plate 103 and the second fixing plate 104 are both T-shaped. The two ends of the connecting spring 105 are welded to the first fixing plate 103 and the second fixing plate 104. The axes of the first fixing rod 106 and the second fixing rod 107 coincide with each other. When in use, by pulling the first fixing plate 103 and the second fixing plate 104 to both sides, the first fixing plate 103 and the second fixing plate 104 can be in close contact with both sides of the ultrasonic welding body under the elastic force of the connecting spring 105. At the same time, through the action of the locking assembly, the first fixing rod 106 and the second fixing rod 107 can be locked with each other, and further the first fixing plate 103 and the second fixing plate 104 are pressed against the ultrasonic welding body, thereby avoiding looseness of the connection between the first fixing plate 103 and the second fixing plate 104 and the ultrasonic welding body, thereby ensuring the welding accuracy of the workpiece.
