Description

Technical Field

[0001] The present invention relates to the technical field of automotive wire harness crimping, and particularly relates to a wire harness crimper. Background Art

[0002] An automotive wire harness refers to a component formed by bundling wire harnesses for connecting circuits. When crimping the wire harness, due to a large number of wire harness crimpings, it is necessary for workers to continuously insert the wire harness ends to be crimped into the crimping area of the wire harness crimper for crimping. However, there is no corresponding protective structure in this crimping area. To ensure that the part to be crimped is properly inserted into the crimping area, the position where the worker grasps the wire harness is relatively close to the wire harness end to be crimped. Long-term and large-scale crimping operations will also have a certain impact on the state of the worker, resulting in the hands of the worker who grasps the wire harness being easily touched or overly close to the crimping area during the crimping operation, causing hand injuries during subsequent crimping, and there are potential safety hazards; the existing wire harness crimper also cannot prevent non-workers from operating the wire harness crimper, resulting in non-workers being able to easily operate the wire harness crimper when the worker temporarily leaves or does not use it, leading to potential safety hazards such as crimping injuries. Summary of the Invention

[0003] In view of this, the present invention provides a wire harness crimper to solve the problem that there is no corresponding protective structure in the crimping area of the existing wire harness crimper, resulting in the hands of the worker being possibly injured during the crimping operation.

[0004] The present invention provides a wire harness crimper, which specifically includes: a base block, a top plate is provided directly above the base block, and the top plate and the base block are fixedly connected by two side support plates distributed symmetrically left and right; a set of electric cylinders are fixedly installed on the top surface of the top plate; a top pressing block is provided directly below the top plate, and the piston end of the electric cylinder penetrates through the top plate and is fixedly installed and connected to the top pressing block; a lower mating block is fixedly installed on the top surface of the base block corresponding to the position of the top pressing block; a lower crimping module is fixedly installed on the top surface of the lower mating block, and an upper crimping module that is crimping-mated with the lower crimping module is fixedly installed on the bottom surface of the top pressing block; two reset receiving grooves are symmetrically opened on the front surface of the lower mating block in a left-right symmetry, and a limiting insertion hole penetrating through the rear end surface of the lower mating block is opened at the central axis of the two reset receiving grooves; a protective cover plate is provided in front of the top pressing block and the lower mating block, and two limiting insertion columns are symmetrically fixedly connected to the lower side of the rear end surface of the protective cover plate; the two limiting insertion columns are respectively inserted and limited in the two limiting insertion holes, and at this time, the protective cover plate blocks the crimping gap between the lower crimping module and the upper crimping module.

[0005] Furthermore, two reset members are fixedly connected in a left-right symmetric manner at the lower side of the rear end face of the protective cover plate. The reset members are springs. The two reset members are respectively sleeved around the two limit insertion posts, and the rear ends of the two reset members are fixedly connected to the rear side faces of the inner ends of the two reset storage grooves respectively; when the reset members are in the extended state, the rear end face of the protective cover plate does not contact the front end face of the lower matching block.

[0006] Furthermore, a crimping fit opening penetrating through its rear end face is formed on the front end face of the protective cover plate, and the crimping fit opening corresponds to the position of the crimping gap between the lower crimping module and the upper crimping module.

[0007] Furthermore, an extension plate is fixedly installed on both the front end face and the rear end face of the base block, and two insertion hole positions penetrating through their bottom end faces are formed in a left-right symmetric manner on the top end faces of the two extension plates; a control box is fixedly installed on the top end face of the top plate, and the electric cylinder is electrically connected to the control box; an inner embedding groove is formed at the center of the front end face of the lower matching block, and a group of crimping control switches are fixedly installed on the rear side face of the inner end of the inner embedding groove. The crimping control switches are touch switches, the key ends of the crimping control switches face forward, and the crimping control switches are electrically connected to the control box.

[0008] Furthermore, when the reset members are in the extended state and the crimping control switches are also in the un-pressed and un-activated state, the front end face of the key end of the crimping control switch contacts the rear end face of the protective cover plate; when the crimping control switches are in the pressed and activated state, the crimping control switches feed back signals to the control box, and the control box controls the piston end of the electric cylinder to extend. When there is no signal feedback from the crimping control switches, the control box controls the piston end of the electric cylinder to retract.

[0009] Furthermore, a power supply opening and closing storage cavity is formed on the left side inside the base block, and a group of power supply opening and closing switches are fixedly installed on the right side face of the inner end of the power supply opening and closing storage cavity. The power supply opening and closing switches are touch switches, the key ends of the power supply opening and closing switches face left, and the power supply opening and closing switches are electrically connected to the control box; a locking storage groove in a circular groove structure is formed on the left end face of the base block at the position corresponding to the power supply opening and closing storage cavity, and a threaded through hole communicating with the power supply opening and closing storage cavity is formed at the axial center of the locking storage groove.

[0010] Further, a locking driving block body in the shape of a circular block is inserted into the locking storage groove. A pressing stud is fixedly connected to the central position of the right end face of the locking driving block body, and the pressing stud is in threaded connection with the threaded through hole. The thickness of the locking driving block body is less than the depth of the locking storage groove. When the left end face of the locking driving block body and the left end face of the base block body are in the same vertical plane, the right end face of the pressing stud does not contact the key end of the power on / off switch at this time. When the right end face of the locking driving block body contacts the right inner side face of the locking storage groove, the right end face of the pressing stud contacts the key end of the power on / off switch, and the power on / off switch is in the pressed and started state at this time.

[0011] Further, a locking driving cooperation groove is provided at the central position of the left end face of the locking driving block body. The locking driving cooperation groove is in the shape of an elliptical groove. A locking driving cooperation block matching its structural dimensions is inserted into the locking driving cooperation groove, and a locking twisting member in the shape of a ring is fixedly installed at the central position of the left end face of the locking driving cooperation block.

[0012] The wire harness press provided by the present invention has the following beneficial effects

[0013] 1. Through the cooperative setting of the protective cover plate, the present invention can shield the crimping gap between the lower crimping module and the upper crimping module for realizing wire harness crimping, ensuring that during wire harness crimping, contact is blocked through the protective cover plate, thereby preventing the operator's hand from touching the upper crimping module and the lower crimping module, and thus maximizing the prevention of accidental hand injury to the operator during wire harness crimping operation to ensure operation safety.

[0014] 2. Through the pressing cooperation between the protective cover plate and the crimping control switch, on the basis of realizing crimping protection, by the operator's hand contacting and pressing the protective cover plate, the wire harness can be inserted between the lower crimping module and the upper crimping module through the crimping cooperation opening, and at the same time, the cooperative crimping of the lower crimping module and the upper crimping module can be controlled, so as to automatically realize the wire harness crimping operation without additional pressing control, and the operation is more convenient.

[0015] 3. Through the concealed design of the power on / off switch, the connection and disconnection of the power supply of the present invention need to be controlled through the pressing cooperation between the pressing stud and the power on / off switch. With the special structure design of the locking driving cooperation groove, without the cooperation of the locking driving cooperation block, non-staff cannot adjust the position of the pressing stud, so as to ensure that when the operator does not use or temporarily leaves, non-staff cannot start and use the wire harness press of the present invention to avoid the occurrence of safety accidents.

The reset members 203 are springs. The two reset members 203 are respectively sleeved around the two limit insertion posts 202, and the rear ends of the two reset members 203 are respectively fixedly connected to the rear side surfaces of the inner ends of the two reset receiving grooves 1012; in the extended state of the reset members 203, the rear end surface of the protective cover plate 2 does not contact the front end surface of the lower fitting block 108; a crimping and fitting opening 201 penetrating its rear end surface is opened on the front end surface of the protective cover plate 2, and the crimping and fitting opening 201 corresponds to the position of the crimping gap between the lower crimping module 1010 and the upper crimping module 109.

[0035] Wherein, extension plates 101 are fixedly installed on both the front end face and the rear end face of the base block 1, and two plugging hole positions 102 penetrating through the bottom end face are symmetrically arranged on the top end faces of the two extension plates 101. When the base block 1 is fixedly installed, fasteners such as screws can penetrate through the plugging hole positions 102 and be fixedly connected to the installation end face to realize the fixed installation of the base block 1; a control box 105 is fixedly installed on the top end face of the top plate 103, and the electric cylinder 106 is electrically connected to the control box 105; a built-in groove 1013 is arranged at the center of the front end face of the lower fitting block 108, and a set of pressing control switches 1014 are fixedly installed on the rear side face of the inner end of the built-in groove 1013.

When there is no signal feedback from the pressing control switches 1014, the control box 105 controls the piston end of the electric cylinder 106 to retract.

[0036] Among them, a power-on / off storage cavity 1016 is provided on the left side inside the base block 1, and a group of power-on / off switches 1017 are fixedly installed on the right side surface of the inner end of the power-on / off storage cavity 1016. The power-on / off switch 1017 adopts a touch switch. The button end of the power-on / off switch 1017 faces the left side, and the power-on / off switch 1017 is electrically connected to the control box 105; a locking storage groove 1011 in the shape of a circular groove is provided on the left end surface of the base block 1 at the position corresponding to the power-on / off storage cavity 1016, and a threaded through hole 1018 communicating with the power-on / off storage cavity 1016 is provided at the center of the locking storage groove 1011; a locking driving block 3 in the shape of a circular block is inserted into the locking storage groove 1011, and a pressing stud 301 is fixedly connected to the center of the right end surface of the locking driving block 3, and the pressing stud 301 is threadedly connected to the threaded through hole 1018; the thickness of the locking driving block 3 is less than the depth of the locking storage groove 1011; when the left end surface of the locking driving block 3 is in the same vertical plane as the left end surface of the base block 1, the right end surface of the pressing stud 301 does not contact the button end of the power-on / off switch 1017 at this time; when the right end surface of the locking driving block 3 contacts the right side surface of the inner end of the locking storage groove 1011, the right end surface of the pressing stud 301 contacts the button end of the power-on / off switch 1017 at this time, and the power-on / off switch 1017 is in a pressed and started state at this time; a locking driving cooperation groove 302 is provided at the center of the left end surface of the locking driving block 3, and the locking driving cooperation groove 302 is in the shape of an elliptical groove; a locking driving cooperation block 303 matching its structural dimensions is inserted into the locking driving cooperation groove 302, and a locking twisting member 304 in the shape of a ring is fixedly installed at the center of the left end surface of the locking driving cooperation block 303. Through the design of the ring structure, when the locking driving cooperation block 303 is carried by the staff, the locking twisting member 304 can be sleeved on a portable object such as a keychain, which is convenient for carrying around.

[0037] Specific usage method and function of this embodiment:

[0038] When the wire harness crimping is applied, the staff first insert the portable locking driving cooperation block 303 into the locking driving cooperation groove 302 and pinch and turn the locking twisting member 304 to synchronously drive the pressing stud 301 to rotate rightward along the threaded through hole 1018 until the right end surface of the pressing stud 301 presses the button end of the power-on / off switch 1017 to realize power-on.

[0039] The operator holds the wire harness to be crimped. When crimping, the end of the wire harness to be crimped is aligned with the crimping mating opening 201 and inserted. Since the crimping mating opening 201 corresponds to the position of the crimping gap between the lower crimping module 1010 and the upper crimping module 109, at this time, the end of the wire harness to be crimped is located between the upper crimping module 109 and the lower crimping module 1010 for realizing crimping. And at this time, the hand of the operator holding the wire harness can simultaneously press against the protective cover plate 2, so that the protective cover plate 2 moves backward. When the protective cover plate 2 moves backward, the two limit insertion posts 202 slide backward along the limit insertion holes 1015, and the reset member 203 is compressed. And at this time, the protective cover plate 2 will also press against the button end of the crimping control switch 1014. The crimping control switch 1014 gives a feedback signal to the control box 105, and the control box 105 controls the piston end of the electric cylinder 106 to extend. When the piston end of the electric cylinder 106 extends, it will drive the upper pressing block 107 and the upper crimping module 109 to move downward, so that the upper crimping module 109 and the lower crimping module 1010 jointly perform a crimping operation on the end of the wire harness to be crimped placed therebetween. And when the crimping contact is made, the operator only needs not to press against the protective cover plate 2 anymore. Without the pressing of the operator's hand, the reset member 203 in the compressed state quickly resets and rebounds, thereby automatically pushing the protective cover plate 2 back to its original position. And at this time, without the pressing of the protective cover plate 2 against the button end of the crimping control switch 1014, the button end of the crimping control switch 1014 will also automatically reset. Without the signal feedback of the crimping control switch 1014, the control box 105 will also control the piston end of the electric cylinder 106 to retract. At this time, the operator can take out the crimped wire harness to perform the crimping operation on the next wire harness; Further, the present invention shields the crimping gap between the lower crimping module 1010 and the upper crimping module 109 through the protective cover plate 2, ensuring that when the wire harness is crimped, the operator's hand will not touch the upper crimping module 109 and the lower crimping module 1010, thereby ensuring that the operator's hand will not be accidentally crushed and ensuring the operation safety;

[0040] And when the operator does not use or temporarily leaves, in order to avoid safety accidents such as being crushed caused by non-operator operation, the operator can pinch and turn the locking and twisting member 304 to synchronously drive the pressing stud 301 to rotate leftward along the threaded through hole 1018, so that the right end face of the pressing stud 301 no longer presses against the button end of the power on / off switch 1017, thereby cutting off the power. And the locking drive fitting block 303 can be carried by the operator. And through the locking drive fitting groove 302 with an oval groove structure, without the insertion of the locking drive fitting block 303, it is impossible to drive the locking drive block 3 to rotate by inserting a common tool into the locking drive fitting groove 302, thereby preventing non-operators from starting the present invention when the operator does not use or temporarily leaves.

[0041] The above description is only an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
