Description

Technical Field

[0001] The utility model relates to the technical field of rivet pressing tooling, in particular to a metal substrate rivet pressing tooling. Background Art

[0002] When riveting the rivet to the metal substrate, a pressing tool is required for auxiliary work. The rivet is fixed on the chuck and sent to the metal substrate for riveting by an air pump. For example, in the patent number "CN216656208U" and the patent name "Rivet Pressing Jig", the workpiece to be processed is first placed on the workbench, and then the rivet is placed in the rivet groove of the rivet fixing chuck. The magnet absorbs the rivet or the anti-slip ball supports the rivet through the rear end spring. The hand-held part of the pressure rod is held and moved to the required riveting position, that is, the rivet is just above the rivet mounting hole of the workpiece to be processed, and then the pressure rod is pressed downward and quickly pressed to the bottom at one time. At this time, the bottom surface of the counterweight block contacts the plane of the riveted part, and the rivet is pressed into the mounting hole. Since the rivet and the mounting hole are interference fit, when the rivet is pressed into the mounting hole, the pressure rod is lifted, the rivet is separated from the rivet groove, and a rivet pressing operation is completed. However, the above structure still has the following problems during actual use:

[0003] However, when the rivet fixing chuck is used for too long or needs to fix rivets of different sizes, it needs to be replaced. The above-mentioned rivet fixing chuck is fixed by screws, and tools need to be used for replacement when replacement is needed. The replacement process is complicated and time-consuming, and inconvenient to use.

[0004] Therefore, we proposed that the metal substrate rivet press-in tooling can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a metal substrate rivet pressing tool to solve the problem raised by the above background technology that the rivet fixing chuck on the current market is fixed by screws, and when it needs to be replaced, tools need to be used for replacement, the replacement process is complicated and time-consuming, and it is inconvenient to use.

[0006] To achieve the above object, the utility model provides the following technical solution: a metal substrate rivet pressing tool, comprising a base, a column is welded and fixed to the upper surface of the base, and the top of the column is fixed to the top plate;

[0007] It also includes: a cylinder is vertically fixed through the middle of the top plate, a mounting head is fixed at the lower end of the cylinder, a rivet clamp is clamped inside the mounting head, and a clamping hole is opened on the outer side of the rivet clamp;

[0008] A clamping rod is clamped inside the clamping hole, and the clamping rod is slidably connected to the mounting head via a reset spring, and two ends of the reset spring are respectively fixed to the clamping rod and the mounting head.

[0009] Preferably, two groups of the clamping rods are provided, and the lower surfaces of the inner ends of the clamping rods are provided with an inclined structure.

[0010] Preferably, a pressure rod is fixed to the outer side surface of the mounting head, and the lower surface of the outer end of the pressure rod is in contact with the force-bearing rod, and the outer end of the force-bearing rod is fixed to the gear rod.

[0011] Preferably, the lower end of the gear rod penetrates into the base, and a gear is meshed on the inner side of the gear rod, and a rotating shaft is fixed in the middle of the gear, and the front and rear ends of the rotating shaft are connected to the base bearing.

[0012] Preferably, a torsion spring is sleeved on the outer side surface of the rear end of the rotating shaft, and a pull rope is wound around the outer side surface of the front end of the rotating shaft, and the other end of the pull rope is fixed to the clamping plate.

[0013] Preferably, the clamping plate is slidably connected to the base via a pressure spring, and two ends of the pressure spring are respectively fixed to the base and the clamping plate.

[0014] Preferably, two groups of the clamping plates are provided, and the clamping plates are arranged in a "7"-shaped structure.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the metal substrate rivet is pressed into the tooling, which not only does not need to be replaced with other tools, saving time and effort, but also facilitates the clamping of the metal substrate, thereby achieving the effect of limiting, avoiding the movement of the metal substrate during riveting, and conveniently releasing the clamping limit of the metal substrate, and then the metal substrate can be removed. The specific contents are as follows:

[0016] (1) The rivet chuck squeezes the clamp rod, causing the clamp rod to slide outward. When the rivet chuck drives the clamp hole to move parallel to the clamp rod, the elastic force of the reset spring drives the clamp rod to reset, thereby fixing the rivet chuck. No other tools are required for replacement, saving time and effort.

[0017] (2) By pulling the clamping rod, the clamping rod is moved outward, so that the inner end of the clamping rod is separated from the clamping hole, and then the rivet clamp can be separated from the installation head, and the rivet clamp can be replaced;

[0018] (3) The gear rod drives the meshing gears to rotate together, thereby causing the rotating shaft to rotate together, so that the rotating shaft reels the pull rope, and the pull rope pulls the clamping plate downward, so that the clamping plate clamps the metal substrate, thereby achieving a limiting effect and preventing the metal substrate from moving during riveting;

[0019] (4) The cylinder drives the installation head downward, and the installation head drives the rivet chuck downward, and the rivet chuck drives the rivet close to the metal substrate, thereby achieving the riveting effect;

[0020] (5) The elastic force generated by the torsion spring drives the rotating shaft to reverse, which not only stops the pull rope from being wound up, but also drives the gear to reverse. The pull rope no longer generates tension on the clamping plate. The elastic force of the pressure spring drives the pressure spring to reset, thereby releasing the clamping limit on the metal substrate, and the metal substrate can then be removed.

DETAILED DESCRIPTION

[0028] 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 in 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.

[0029] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem in the prior art that the rivet fixing chuck is fixed by screws, and when it needs to be replaced, tools need to be used for replacement, and the replacement process is complicated, time-consuming, and inconvenient to use, the following technical scheme is disclosed, including a base 1, a column 2 is welded and fixed on the upper surface of the base 1, and the top of the column 2 is fixed to the top plate 3; it also includes: a cylinder 4 is vertically penetrated and fixed in the middle of the top plate 3, and a mounting head 5 is fixed at the lower end of the cylinder 4, and a rivet chuck 6 is clamped inside the mounting head 5, and a clamping hole 7 is opened on the outer side of the rivet chuck 6; a clamping rod 8 is clamped inside the clamping hole 7, and the clamping rod 8 is slidably connected with the mounting head 5 through a reset spring 9, and the two ends of the reset spring 9 are respectively fixed to the clamping rod 8 and the mounting head 5, and two groups of clamping rods 8 are provided, and the lower surface of the inner end of the clamping rod 8 is arranged as an inclined structure;

[0031] By pulling the clamping rod 8, the clamping rod 8 is moved outward, so that the inner end of the clamping rod 8 is separated from the clamping hole 7, and then the rivet clamp 6 can be separated from the installation head 5, and the rivet clamp 6 can be replaced, and then the new rivet clamp 6 is directly connected to the installation head 5. At this time, the clamping rod 8 is squeezed by the rivet clamp 6, so that the clamping rod 8 slides outward, so that the rivet clamp 6 can continue to slide into the installation head 5. When the rivet clamp 6 drives the clamping hole 7 to move parallel to the clamping rod 8, the elastic force of the reset spring 9 drives the clamping rod 8 to reset, so that the inner end of the clamping rod 8 is clamped with the clamping hole 7 again, thereby fixing the rivet clamp 6, and no other tools are needed for replacement, which saves time and effort;

[0032] Embodiment 2: Different from Embodiment 1, this embodiment realizes clamping of the metal substrate. Figure 2 and Figure 5-Figure 6 A pressure rod 10 is fixed to the outer side of the mounting head 5, and the lower surface of the outer end of the pressure rod 10 is in contact with the force rod 11, and the outer end of the force rod 11 is fixed to the gear rod 12, the lower end of the gear rod 12 penetrates into the base 1, and the inner side of the gear rod 12 is meshed with a gear 13, and a rotating shaft 14 is fixed in the middle of the gear 13, and the front and rear ends of the rotating shaft 14 are connected to the bearings of the base 1;

[0033] When the cylinder 4 drives the mounting head 5 downward, the mounting head 5 also drives the pressure rod 10 downward. The pressure rod 10 moves downward, and the pressure rod 10 presses the force-bearing rod 11 downward, and the force-bearing rod 11 drives the gear rod 12 to slide downward. The gear rod 12 slides downward, and the gear rod 12 drives the meshing gear 13 to rotate together. The gear 13 rotates, and the shaft 14 rotates together. The shaft 14 rotates, and the shaft 14 winds up the pull rope 16, and the pull rope 16 pulls the clamping plate 17 downward, and the clamping plate 17 clamps the metal substrate, thereby achieving a limiting effect to prevent the metal substrate from moving during riveting.

[0034] Embodiment 3: Different from Embodiment 2, this embodiment facilitates the release of the clamping limit of the metal substrate. Figure 5-Figure 6 A torsion spring 15 is sleeved on the outer side surface of the rear end of the rotating shaft 14, and a pull rope 16 is wound around the outer side surface of the front end of the rotating shaft 14, and the other end of the pull rope 16 is fixed to a clamping plate 17, and the clamping plate 17 is slidably connected to the base 1 through a pressure spring 18, and the two ends of the pressure spring 18 are respectively fixed to the base 1 and the clamping plate 17, and two groups of clamping plates 17 are provided, and the clamping plates 17 are arranged in a "7" shape;

[0035] When the cylinder 4 drives the mounting head 5 upward, the pressure rod 10 will no longer generate pressure on the force-bearing rod 11. At this time, the elastic force generated by the torsion spring 15 drives the rotating shaft 14 to reverse. The reversal of the rotating shaft 14 not only makes it no longer reel in the pull rope 16, but also drives the gear 13 to reverse, so that the gear 13 drives the meshing toothed rod 12 to slide upward, so that the toothed rod 12 drives the force-bearing rod 11 to reset for the next use. The pull rope 16 no longer generates tension on the clamping plate 17. At this time, the elastic force of the pressure spring 18 drives the pressure spring 18 to reset, thereby releasing the clamping limit of the metal substrate, and then the metal substrate can be removed.
