[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0029] As shown in the figure, the utility model discloses a riveting clamp for a terminal block, which comprises:
[0030] The base 1 is a flat plate structure, which supports the entire riveting fixture;
[0031] A detachable clamp base 2 is arranged on the base, and positioning pieces 9 for limiting the terminal cover are symmetrically arranged on the clamp base, and a limiting groove 10 for accommodating the terminal cover is formed between the two positioning pieces, and an avoidance groove 91 for avoiding the protrusion of the terminal cover is provided on one side of the positioning piece;
[0032] The pressing head assembly 5 is located above the connection between the terminal cover and the pressing plate placed on the fixture base, and includes a replaceable pressing head 51, which can be replaced according to the type of the pressing plate, and uses the impact force to press the pressing plate 4 into the limit slot of the terminal cover 3, and at the same time presses the tensile cylindrical step next to the through hole of the pressing plate into the hole of the terminal cover;
[0033] The driving component 6 applies force to move the pressing head along the riveting direction of the pressing plate and the terminal cover. The driving component can be electric or manual. The present application takes manual as an example.
[0034] The entire fixture base can be replaced according to the different terminal covers and pressure plates that need to be riveted, and because the terminal cover is in an I-shape as a whole, it directly relies on two relatively arranged positioning pieces, which are used together with the terminal cover to form a positioning, and can achieve precise loading. At the same time, the avoidance groove design on one side of the positioning piece can avoid the protrusions on the inner side of the terminal cover, making the installation faster and also having a fool-proof effect.
[0035] An inclined surface 92 is provided on one side opposite to the two positioning members, and the two are arranged relative to each other to form an installation opening, which is connected to the limiting groove. The installation opening gradually narrows from top to bottom and finally matches the width of the limiting groove, thereby facilitating the terminal cover to be installed into the limiting groove.

[0037] The upper end of the support plate is provided with a relatively arranged elbow clamp mounting plate 8, and the driving assembly is fixedly arranged on the elbow clamp mounting plate. The design of the elbow clamp mounting plate can make the support plate away from the clamp base position to avoid the support plate affecting the placement of the terminal cover and the pressure plate, which is convenient for operation.
[0038] The driving assembly includes a mounting frame 61 with a guide hole 611, a manual pressure rod 62 rotatably arranged on the mounting frame, a movable rod 63 movably arranged in the guide hole, and a connecting rod 64 connecting the manual pressure rod and the movable rod. One end of the manual pressure rod is pivotally connected to the mounting frame, the connecting rod is pivotally connected to the middle position of the manual pressure rod, and the manual pressure rod can drive the movable rod to move along the axial direction of the guide hole through the connecting rod.

[0040] The connecting plate is a “)” type connecting plate.
[0041] The manual pressure rod drives the movable rod to move up and down, thereby realizing the riveting action of the pressure head on the pressure plate.
[0042] The manual pressure rod and connecting rod can be replaced with a motor or hydraulic rod to achieve automatic riveting.
[0043] The pressure head is connected to the bottom of the movable rod through the pressure head positioning block 52, and the pressure head positioning block is fixedly connected to the movable rod to limit the position of the pressure head.
[0044] The pressure head includes a pressing surface 511 matched with the pressing plate and a protrusion 512 arranged perpendicular to the pressing surface. The protrusion is located on the outside of the pressing surface and can play a protective role.
